Product Description
CUHD-A Series Marine UPS Single-input single-output Power Supply
Features
This series of products complies with the specifications and standards of domestic and international shipbuilding industry related electrical equipment.
Online double conversion design provides excellent power supply quality and protection for the load.
DSP digital control technology is adopted, with fast control response speed and high reliability.
Built-in isolation transformer design, strong impact resistance, can effectively suppress high-frequency noise, ensure reliable operation of the load; isolate dangerous voltage to ensure personnel safety.
The structure adopts front airflow and top airflow, front maintenance design, and testing and maintenance are more convenient.
Intelligent heat dissipation design: The fan automatically matches the speed with the load size, effectively reduces noise, and prolongs the service life of the fan.
Multi-channel passive dry contact output can monitor all possible states during UPS operation.
All-round protection function: with input over-voltage and under-voltage, phase loss, output overload, short circuit, battery over-voltage and under-voltage, over-temperature and other protection functions.
Rich intelligent communication interfaces: RS232, RS485, SNMP intelligent slot.
This series of products can provide full customization of functions, sizes, and installation methods.
The entire series of AC UPS power supplies have been type approved by China Classification Society.
