PS-305D communication maintenance power supply


PS-305D 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. 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.
