Marine DC UPS Power Supply

Marine DC UPS Power Supply Application

Power supply adopts the control mode of pulse width modulation, power supply has the advantages of small size, high efficiency, stable output waveform, etc.

Marine DC UPS Power Supply has the characteristics of general UPS power, while considering the characteristics of the ship and the environmental requirements, the power supply products according to ABS and CCS specifications for design, meet the standards of marine electric.

Marine DC UPS Power Supply Features

1)Complete range of input voltage
a) single line single phase AC AC220V
b) two line single phase AC AC220V
c) three phase 380VAC

d) direct current DC24V

2)advanced battery management: three step charging,float charging,equalizing charge can be automatic converted, improved the battery protection.

3)perfect protection measures: output short circuit, overload protection, the whole machine overheat protection; the input DC protection and the protection of DC over voltage protection.

4)When the AC power out,the power supply can be switched to the input DC power supply (or battery power supply) uninterruptedly,so as to ensure uninterrupted output,out put no flush.
