Installation Location, Mounting, and Ventilation Figure 2.
Installation Location, Mounting, and Ventilation Figure 2.3 Mounting the Power Supply in the Rack With Support Rails1 (6000 W shown) Ventilation Allow cooling air to reach the ventilation inlets on the front of the unit and allow 4 in. (10 cm) of unrestricted air space at the rear of the unit for the fan exhaust. Ventilation inlets are located on the top and sides; they are not required, however, and may be blocked, if required.
Installation AC Input Power AC Input Power WARNING Disconnect AC power from the unit before removing the connector cover. Live line voltages may be exposed when the cover is removed. WARNING A safety ground wire must be connected to the unit as shown in Figure 2.4 and Figure 2.6 to ensure operator safety. ! CAUTION When the power switch is turned on, output voltage or current previously set may be applied to loads, depending on the supply configuration.
Installation AC Input Power AC Input Wire The manufacturer recommends the AC input wire specified in Table 2.2 and Table 2.3. This must be permanently connected to an approved AC distribution box with suitably rated over-current protection. If you require a special cord, contact the manufacturer. Table 2.2 AC Wire Specification for 6000 Watt units AC Input Voltage Range Wire 190–242Vac, 47–63Hz, 3-phase, 4 wire (standard) 4 x 10 AWG (3 wire plus safety ground), stranded copper, 60°C minimum, 300V, 0.
Installation AC Input Power 6. Route the AC wires to the input terminal block by connecting the red, black, and white wires to the remaining 3 cable clamp connectors. There is no set order for connecting the wires. Any of the 3-phase wires can be connected to any of the 3 line input connectors. To connect each wire, loosen the terminal screw, insert the stripped wire 0.55 in. (14mm) into the terminal, and tighten the screw securely. 7.
Installation AC Input Power AC Wire Input See Figure 2.6, on page 44. Connection for 12000 W To connect the 12000 W AC input wires: 1. Ensure that the AC input cord is de-energized, and that the power switch on the front of the power supply is OFF. 2. Strip approximately 2.75 in. (70 mm) from the jacket of the AC wire. Strip 0.55 in. (14 mm) at the end of each wire. 3.
Installation AC Input Power left terminal: Ground Connection 3 right terminals: 3-Phase Terminal Block Connectors AC input cover plate Figure 2.
Installation Basic Checks or Self-Tests Basic Checks or Self-Tests WARNING The factory setting for Power ON is 0V and 0A with the output OFF. These settings can be customized by end users. If you suspect that the power supply has been used by someone else since it was received from the factory, be prepared for the unit to power ON with a live DC output.
Installation Basic Checks or Self-Tests Power ON To complete the power on check: Check 1. Ensure that the AC power switch is OFF. 2. Connect the unit to an AC outlet. 3. Turn the front panel AC power switch to ON. After a short power-on delay, the front panel digital meters and the CV annunciator illuminate. Both voltmeter and ammeter displays should read zero. Check the front panel annunciators. If OUT ON is illuminated, press OUT ON/OFF to disable the output.
Installation Basic Checks or Self-Tests 4. Slowly turn the Current knob clockwise 1 or 2 turns. Slowly turn the Voltage knob clockwise and observe both the front panel voltmeter and the DVM. Do not exceed 10V. 5. Compare the DVM reading with the front panel voltmeter reading to verify the accuracy of the internal voltmeter. Both readings should be the same within the accuracy of the meters. The minimum control range is from zero to the maximum rated output for the power supply model.
Installation Load Wiring Load Wiring When connecting load wiring to the power supply, consider the following factors: • • • Current carrying capacity of the wire Maximum load wiring length for operation with sense lines Noise and impedance effects of the load lines Current As a minimum, load wiring must have a constant capacity greater than the output Carrying current rating of the power supply. This ensures that the wiring will not be damaged Capacity even if the load is shorted. Table 2.4.
Installation Load Wiring Load Wiring Length for Operation with Sense Lines For applications using remote sensing, or for improved voltage regulation at the load, you must limit the voltage drop across each load line. We recommend that you use the larger load wiring to ensure a smaller voltage drop (1V maximum), although units will compensate for up to 5V drop in each line with the remote sense lines connected.
Installation Load Connections Load Connections WARNING Exercise caution when operating the power supply. High energy levels can be stored at the output terminals on a power supply in normal operation. In addition, potentially lethal voltages exist in the power circuit and on the output and sense connectors of a power supply with a rated output greater than 40V. Filter capacitors store potentially dangerous energy for some time after power is removed.
Installation Load Connections Single Load To connect a single load to the DC output bus bars (10–150V outputs): 1. Ensure that the power supply is powered OFF. 2. Place a bolt in the connecting hole of the negative bus bar, and fasten the negative wire or bus bar, a washer, and a nut to the bolt. 3. Using a wrench, turn the bolt until it is secure at approximately 25 foot-pounds (34Nm). 4. Fasten the positive wire or bus bar to the positive bus, using a bolt, washer, and nut. 5.
Installation Load Connections Multiple To connect multiple loads in parallel: Loads • Follow the “Single Load” procedure with the following exception: • To minimize interaction between loads, bring the wiring for each load directly back to the supply output. When each load to the power supply is wired separately, the loads will see only the precisely regulated output from the supply. If 2 loads share a single cable, the fluctuation in current to one load will cause the voltage to vary on the others.
Installation Load Connections Output Strain See Figure 2.8 and Figure 2.9 for installation of the output cover. Use this cover to Relief/Cover protect users from accidental contact with the bus bars and to clamp output cables in place. Figure 2.8 Output Bus Bar Cover for 6000 Watt units (Low and Medium Voltage) Figure 2.9 Output for 12000 Watt units (Low and Medium Voltage) Release 3.
Installation Load Connections Figure 2.
Installation Load Connections Figure 2.11 Output for 12000 Watt units (High Voltage 300–600V) Release 3.
Installation Remote Sensing Remote Sensing The power supply regulates the output voltage at the output connectors in its normal configuration without remote sense lines connected. Remote sensing lets the power supply track and regulate the output voltage at the load, and thereby compensate for the voltage drop in the load lines. The power supply will only compensate within the limitations of its voltage rating, to a maximum of 5V per load line.
Section 3. Operation Overview Once you have installed the power supply and connected both the AC input power and the load as explained in Section 2, the power supply is in its default configuration and is ready to operate in local control mode. Section 3 begins by explaining how to power on and power off the power supply. It then provides information about configuring the power supply, and also gives procedures for operating the supply via the front panel controls and menu functions.
Operation Power Supply Operating States Powering From the front panel, the safest method for shutting down the power supply is: OFF the Step # Do This You Will See Power Supply 1 2 ON OUT OFF Switch the AC power to OFF. The OUT OFF annunciator illuminates; Ouput V and I are 0. The AC OFF alarm, and then the unit fades to black.
Operation Power Supply Regulation Modes Power Supply Regulation Modes The power supply has 3 regulation modes while in the Normal Operation State: • • • Constant Voltage (CV) Constant Current (CC) Constant Power (CP) The CV, CC, and CP annunciators indicate the regulation mode. Constant In this mode, the supply’s output voltage is constant while the current and power Voltage (CV) vary with the load.
Operation Remote Control Modes Remote Control Modes A number of control interfaces are available. You can control the power supply remotely using 0–5V or 0–10V signals via the remote analog programming interface or from a remote terminal using a remote digital interface. A remote digital interface following RS-232 protocol is standard. An optional remote digital interface following IEEE 488.2 (GPIB) protocol is also available.

Remote Operation SCPI Commands for Digital Interfaces Status Byte The Status byte register contains the STB and RQS(MSS) messages as defined in 488.1. The user can read the status byte register using a 488.1 serial poll or the 488.2 *STB? common command. If the user sends a serial poll, bit 6 will respond with Request Service (RSQ). The value of the status byte is not altered by a serial poll.
Remote Operation SCPI Commands for Digital Interfaces Questionable Status Register Summary (QSR) This bit is TRUE when a bit in the Questionable Event Status Register is set and its corresponding bit in the Questionable Status Enable Register is TRUE. Message Available (MAV) This bit is TRUE whenever the power supply is ready to accept a request by the Digital Programming Interface to output data bytes. This message is FALSE when the output queue is empty.
Remote Operation SCPI Commands for Digital Interfaces Status In the following sections is a value from 0 to 32767 representing a Register 15-bit register mask. Commands SCPI Status Commands Preset Status Configures the status data structures to ensure that certain events are reported at a higher level through the status-reporting mechanism. These events are summarized in the mandatory structures, the Operation Status Register, and Questionable Status Register.

Remote Operation SCPI Commands for Digital Interfaces Service Request Enable Register The Service Request Enable Register allows the user to select the reasons for the power supply to issue a service request. The Service Request Enable Register allows the user to select which summary messages in the Status Byte Register may cause service requests. To clear the Service Request Enable Register send "*SRE 0.
Remote Operation SCPI Commands for Digital Interfaces Status Byte The status byte query will return the contents of the status byte register and the MSS (Master Summary Status) message. The response is in the format of a weighted decimal value representing the status byte register and the MSS message (bit 6). Thus, the response to *STB? is identical to the response to a serial poll except that the MSS message appears in bit 5 in place of the RQS message. (See “Status Byte” on page 155 for details.

Section 5. Current Sharing (6000 Watt only) Overview The current sharing function is only available for 6000 Watt units. Power supplies can be equipped with the optional CANbus interface to allow current sharing between units connected in parallel. Current sharing can use a maximum of 5 supplies. All power supplies must be the same model. Every unit must have a unique address. See “Multichannel Operation (6000 Watt only)” on page 113. Figure 5.
Current Sharing (6000 Watt only) Overview Configure Current sharing may be configured either by SCPI commands sent via a remote Current interface or by using the Front Panel. The current sharing modes available are: Share • No sharing • Master: sets up the unit as the master controller. • Slave: sets up the unit as the controlled slave. Front Panel In addition to selecting the current share mode, the master may be set up to display the summed current from all units.
Current Sharing (6000 Watt only) Overview SCPI Select whether the unit will operate as a master or slave unit: SOURCE:COMBine:CSHare:MODE [MASTer | SLAVe | OFF] To query the total output current of all current sharing units, use the SCPI command: MEAS:CURR? SUM The current share subregister (CSHare) will show whether the master or slave is operating. STAT:OPER:CSH:COND? See Table 4.14, “Current SHare Sub-Register,” on page 148 for a description of the bits in this register.
Current Sharing (6000 Watt only) Operation Operation Once a current sharing network is setup, you may adjust the voltage setpoint on the master. The master will automatically adjust the setpoints of the slave units to equalize the current output of all units. You may also disable or enable the output of the master, automatically disabling or enabling the output of all slaves. You may use local or remote (RS-232, GPIB, multichannel or analog) control to operate the master.
