Power supply D12-20-AC220
Power supply (charge device) D12-20 is intended for the feed of devices on vessels, by voltage 12 V at a current to 20 A (charging of accumulator) from the network of alternating curren (50 Hz), also for the feed of any other apparatus by the voltage 20 V.
Power supply is certificated in Register of navigation the Ukraine – №STS-32-3-044-09.
Distinvtive features of the product:
- battery can automatic charge and subcharge with the U/I characteristic ;
- controlled from distance signaling (dry contacts) of presence of entrance network and output voltage;
- pointer indication of output voltage, current of charge (digit) of battery;
- instantaneous switching of burden on the output voltage from an accumulator and return to the power supply accordingly at disappearance and appearance of input voltage.
