SPECIFICATION

YIHUA-302D/303D DC power supply is a single output precision DC power supply. Its output voltage and current are continuously adjustable within the rated range. The load current with MA conversion is divided into two grades such as 0-2A / 0-3A and 0-999 mA. The two grades with constant voltage constant current can automatically convert the work mode.

This power supply unit has dual digital display screen to independently display the output voltage and output current. It has a variety of protection functions, for example, current limiting, short circuit protection, over-temperature protection, and the like. Therefore, our power unit can be used for production lines, maintenance, and debugging in factories. Also, it can be applied in laboratories or other places. The DC power supply is the essential instrument of the communications industry.

 

Main Function

1. Output constant current adjustable.

2. Output constant voltage adjustable.

3. LCD voltage and current display.

4. Constant voltage and current operation in individual.
5. Over current protection.
