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.
