Marine AC UPS Power Supply
Marine AC 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 AC 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 AC UPS Power Supply Features
1)pure sine wave output: the effect of AC input harmonics on the load can be completely be inhibited,and it can always provide a full range of protection and high quality sine wave power supply.
2)the input AC voltage range is 176-264VAC, the input frequency is 45HZ-65HZ. Output DC DC20-32V.
3)advanced battery management: three step charging,float charging,equalizing charge can be automatic converted, improved the battery protection.
4)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.
5)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.
