5. Description
The LABPS3005D is a highly accurate, DC-regulated power supply with an adjustable output. This output
can be used for constant voltage (C.V.) and constant current (C.C.).
The output voltage can be adjusted between 0V and 30V when the device is in the constant voltage
mode. The current-limiting point can be set arbitrarily in this mode.
The output current can be adjusted continuously between 0A and 5A in the constant current mode.
The output current and voltage are indicated on the LED displays.
Refer to the illustrations on page 2 of this manual.

6. Operation
Switching the Power Supply On or Off
1. Connect the included power cord to the back of the device [23] and plug the other end into a
suitable, earthed power socket.
Always connect the device to an earthed power socket.
2. Press the Power button [19] to switch the power supply on.
The power supply automatically recalls the settings from memory 1. (See Setting Voltage and
Current for more information.) The display shows the existing settings, the M1 indicator [13]
lights.
At this moment, there is no output voltage or current on the output terminals.
3. Press the Power button [19] to switch the power supply off.
