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.
- 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.
- 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.
