The shipping container should contain the following items: power supply, HV output cable, male 15-pin "D" remote control connector and operator's manual. Examine the items immediately for damage. Locate the serial number label on the side of the power supply and verify the model number, the input voltage rating and the output voltage rating and polarity. In the event of any damage promptly notify the transportation company and the Lambda EMI Customer Service Manager.
The PFC version connection is shown in Figure 3-2. Connect the input voltage line wires to L2 and COM terminals. WARNING: 152A and 202A PFC Models are only available with 220 VAC Nominal. For 152A Models Suffix 110 at 110-120 VAC must be operated with the internal fuses F1 and F2 (on the Inverter Board) replaced by copper bus provided with the supply. Use external 30A UL/VDC Approved Fuse/Circuit Breaker. NOTE: For Application At less than 10 Hz Please see section 5.7.
POTENTIAL LETHAL VOLTAGE Ensure that the power supply is off and disconnected from the input power and never operate the power supply without a load cap. Make sure that all load capacitors are discharged and shorted to ground before making any connections. Lambda EMI recommends the use of safety dump switches in high voltage discharge circuits. Never handle the HV cable during operation. This power supply is designed to operate with a capacitive load.
3.6.1 GROUNDING OF INPUT LINE The supply is grounded through the ground terminal of the input connector. A protective ground connection by the way of the grounding conductor in the input terminal is essential for safe operation. 3.6.2 OUTPUT GROUND CONNECTION It is important that there be a ground connecting the supply to the load as shown in Figure 3-3. See Figure 2-1 and 2-2, for grounding cable configuration. Figure 3-3 Output Ground Connection 3.6.
The Series 500A/102A/152A/202A is easily controlled through the remote connector on the input panel of the unit. Only the ENABLE/RESET, V PROGRAM and GND signals are required for operation. The remaining signals are provided for status monitoring and fault diagnosis. A schematic diagram showing the suggested interface circuit is shown in Figure 4-1. This table is for a standard configuration.

& LETHAL VOLTAGES PRESENT ONLY QUALIFIED PERSONNEL TRAINED IN THE SAFETY ASPECTS OF HIGH VOLTAGE SHOULD PERFORM INITIAL CHECKOUT PROCEDURES. The power supply should have no visible damage or defects and the cover should be securely fastened. Properly connect the input power (Section 3.5), control connector (Sec. 4.1) and HV output (Sec. 3.5, and 3.6).
For clarification and further technical assistance specific to your application, please contact Lambda EMI. The ratings of these supplies are as follows: 500A - 500 J/s, 102A - 1000 J/s, 152A 1500J/s, 202A-2000J/s average charge rate. Although the measure of Joules/sec equates to Watts, Stored Energy per unit time is more convenient when working with energy storage capacitors. The peak charge rate determines the capacitor charge time.
Figure 5.2 Output Current Measurement A series terminating resistor (or series inductor or clamp diode) must be added as shown if the average value of the peak current exceeds 110% of the normal output current. When choosing Rs, ensure it can withstand the full output voltage across it as well as the power dissipation caused by discharging Co (see Table 5.1) and Cc (20pF/ft) (65.62 pf/m) each cycle as well as conducting the normal output current.
WARNING: EXTREME CAUTION MUST ALWAYS BE EXERCISED WHEN TAKING ANY HIGH VOLTAGE MEASUREMENTS. IT SHOULD BE DONE ONLY BY QUALIFIED PERSONNEL WHO ARE TRAINED IN THE SAFETY ASPECTS OF WORKING WITH HIGH VOLTAGE. A sample of the output voltage is available in the REMOTE connector. If it is desired to measure the HV output externally, care must be taken to understand the accuracy of the measurement.
Figure 5.3 HV Bias Measurements IL = P V L P F EFF IL = Line current P = Average output power VL = Line voltage PF = Power factor (.65 min) EFF = 0.85 Ex: A 152A operating from 115V - 10% and delivering 1000W average. IL = 1000 0.9 = 17.5A (115)(.65)(0.85) When charging very large capacitor banks requiring many seconds or minutes to reach end-of-charge, the power supply will display a load fault and go into a 50% duty cycle protection mode.
! ' ( It is advised that you consult the factory if this type of operation is required. On supplies with active Power Factor Correction there is a limit to the length of the charge time. With all capacitor charging supplies, the peak output power capability is twice the joule per second rating. At pulse rates greater than approximately 20Hz, the internal filter capacitors can average the power drawn from the power factor correcting circuit.
ONLY QUALIFIED PERSONNEL TRAINED IN THE SAFETY ASPECTS OF HIGH VOLTAGE SHOULD PERFORM CALIBRATION. The calibration steps described in this section require operation of the power supply with the cover removed. Proceed with extreme caution as hazardous voltages are exposed throughout the unit. Safety glasses must be worn to prevent serious injury in the event of a component failure (e.g., power transistors readily explode during fault conditions).
