Getting started and operation

a) Connection and Start-Up

• Place the lab power supply on an sturdy and even surface.
• Initially, the on/off switch (5) should be in the "OFF" position.
• Plug the IEC connector of the supplied power cord into the power input (14) on the back of the unit and plug the power cord into a 230 V/AC, 50 Hz AC outlet.
• Now switch on the lab power supply by pressing the on/off switch (5) ("ON" position).
• The two LED displays (1 and 2) will be lit showing the currently set current value and the voltage value.
• Depending on the position of the "CURR Coarse" knob (9), which limits the output current, either the "CV" LED display (12) for the output voltage control or the "CC" LED display (11) for the output current control will light up.
• The lab power supply is now ready and you can set the output voltage and the current limit.

b) Setting the output voltage

The output of the lab power supply must be in the voltage-controlled state in order to set the correct output voltage.

• Turn the "CURR Coarse" knob (9) clockwise from the left stop to the output current limit until the current limit LED display "CC" (11) turns off and the voltage control LED "CV" (12) goes on.
• Check the "VOLT Fine" knob (3) for fine voltage adjustment. This control knob should be in the mid-position.
• Turn the "VOLT Coarse" knob (10) to roughly the desired output voltage. The "V" LED display (1) shows the currently set voltage. Voltage increases, when the knob is rotated CW and decreases when the knob is rotated CCW.
• The output voltage is then adjusted to an exact value with the "VOLT Fine" knob (3).

If you need to turn the "VOLT Fine" knob (3) all the way to the stop, move it back to the middle position and adjust the voltage using the "VOLT-Coarse" knob (10). Then adjust further by means of the fine adjustment.

c) Setting the current limit

Read section "d) Connecting loads" before attempting to set any current limits. You have to switch on a connected load and the lab power supply to be able to set the exact current limit.

You can only read the current limit value, which is shown in the "A" LED display (1), during operation.

Adjust first the permissible operating voltage of the load to be operated with the two voltage controls "VOLT Coarse" (10) and "VOLT Fine" (3) (see chapter "b) Setting the output voltage").

• Check the "CURR Fine" knob (4) for fine current adjustment. This control knob should be in the mid-position.
• With the "CURR Coarse" knob (9) adjust the output current limit roughly to the desired current strength.
• The current value increases, when the knob is rotated CW and decreases when the knob is rotated CCW.

If both voltage adjustment knobs (3 and 10) are turned all the way to the left, the voltage display shows "00.0" volts. The lab power supply is in the current-controlled state if after that also the output current limit knobs "CURR Coarse" (9) and "CURR Fine" (4) are turned all the way to the left.

d) Connecting the loads

Make sure that the total power of all loads together is not exceeding the maximum power of the lab power supply.

• The loads must be switched off when connecting the loads to the lab power supply. If this is not the case, possible sparking can damage the output sockets and also the plugs.
• Turn the lab power supply off.
• Connect the positive terminal (+) of the load to the red positive terminal (8) of the lab power supply and the minus terminal (-) of the load to the black negative terminal (6) of the lab power supply. For this you should use adequately dimensioned cables with 4 mm banana plugs or standardized lab cables.
• You can attach cable strands using screw terminals. To this end, the socket heads can be screwed on.
• Use the dedicated ground connection (7) of the lab power supply to earth the load.

- Then switch on the lab power supply and the load.

As soon as voltage is applied to the output sockets and the load is switched on, the current values for current limit and voltage will be shown on the LED displays (1 and 2). Depending on the operating mode of the lab power supply (current- or voltage-controlled), the "CC" LED display (11) for current limit or the "CV" LED display for voltage control (12) will be lit.

• If necessary, you can also readjust the current limit or the value for the voltage control, if the output sockets are disconnected from the mains.
  • Always switch off loads and lab power supply before disconnecting the loads.

The lab power supply has a protection circuit which will limit the current in the event of a short circuit. Always switch off the lab power supply immediately in the event of a short circuit to avoid overheating and disconnect the loads. Let the lab power supply cool down and make sure that the air can circulate freely. The air outlet (13) should always be clean and dust-free; do not cover the openings of the housing.

The maximum uninterrupted operating time of the lab power supply is 24 hours. After that the lab power supply should be switched off until it has cooled down to ambient temperature.
