Product Description
CUHD-D Series Marine DC Uninterruptible Power Supply
Features
This series of products meets the specifications and standards of domestic and international shipbuilding industry related electrical equipment.
Comprehensive protection functions: input undervoltage, overvoltage protection, output overvoltage protection, short circuit and overtemperature protection.
Multi-channel alarm passive dry contact output, can monitor all possible states during UPS operation.
Built-in voltage regulator and charging power modules are both CCS type approved, digital control, parallel design, convenient expansion.
Built-in independent voltage regulator and charging module, humanized battery maintenance: constant current equalization charging - constant voltage equalization charging - floating charge trickle charge three-stage automatic cycle, extending the service life of lead-acid batteries.
Positive maintenance design, testing, and maintenance are more convenient.
This series of products can provide full customization of functions, sizes, and installation methods.
The full range of DC UPS power supplies have been approved by China Classification Society.
