4. Overview

Refer to the illustrations on page 2 of this manual.

#	Function	Description
1	voltage display	indicates the output voltage
2	current display	indicates the output current
3	+ output	used for the connection of the load's positive terminal
4	- output	used for the connection of the load's negative terminal
5	on-off switch
6	current knob	rotary switch for the adjustment of the output current
7	voltage knob	rotary switch for the adjustment of the output voltage

5. Operation

• If you want to use the unit as a stable voltage supply, set the current knob on maximum clockwise. Then switch on the unit and set the voltage knob to the required voltage.
• If you want to use the unit as a stable current supply, turn the unit on, set the voltage knob to the maximum clockwise and the current knob to the minimum counter clockwise. Connect the load and set the current knob to the required current.
• If you want to use the unit as a stable voltage supply, you can set the protection point of the current limit randomly. Set the current knob on the minimum counter clockwise. Then, short-circuit the output terminals and set the current knob clockwise.
• Set the output current to the required limited current point.
• For more accuracy, connect an external high-accuracy meter.

Notes

• This unit is short-circuit protected. If a short circuit should occur, turn the power supply off and solve the problem.
• The unit can get very hot when you are using a high-power output.
• If the unit is defective, the output may rise over the maximum rated voltage. Always keep an eye on the load to prevent damage.
