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.
