YIHUA 303D DC Power Supply


Feature

303D communication maintenance power supply is a single line output of stabilized high accuracy

DC stabilized power supply. The output voltage and current can be adjusted continuously within the

 rated range. The load current has MA conversion with two settings: 0-3A and 0-99 mA. Constant

voltage and constant current (CV/CC), automatic switching of working modes. Double digital display

shows output voltage and current independently. Several protection functions include current

 limitation, voltage reduction, short circuit protection, over-temperature protection, etc. The design

 is applied to production line of the plant, maintenance, laboratories and is also a necessary device

for the communication industry.

Principle description of constant voltage/constant current CV/CC

The operation mode of constant voltage/constant current can be automatically switched depending

on the comparison result of the load current and limited current value.

  1. a) Constant voltage CV

When the existing current value is smaller than the set output limit current value, the power supply

 is working under the constant voltage mode. The CV indicator light on the front panel is on, the

output voltage is controlled and it will be the same as the set value. Current changes with the load.

  1. b) Constant current mode (CC)

When the current value exceeds the limit value of the output current, the equipment will work in

the CC mode. The CC indicator light on the front panel is on, the output current value is controlled

 to the set value. Since the limited output power cannot be overloaded, the output voltage can be

lower than the set value. When the output current is lower than the set value, the equipment will

automatically change to CC mode.
