CUHD-D Marine DC uninterruptible power supply:
This series of products meet the specifications and standards of domestic and international marine industry related electrical equipment.
1. Comprehensive protection functions: with input undervoltage, overvoltage protection, output overvoltage protection, short circuit and overtemperature protection.
2. Multi-channel alarm passive dry contact output can monitor all states that may occur during UPS operation.
3. The built-in regulated power supply and charging power module have obtained CCS type approval, digital control, and parallel design for easy expansion.
4. Built-in independent voltage stabilization and charging module, user-friendly battery maintenance: constant current equalization charge-constant voltage equalization charge-float charge trickle charge three-phase automatic cycle to extend the service life of lead-acid batteries.
5. Front maintenance design, testing and maintenance are more convenient.
6. This series of products can provide all elements of function, size and installation.
7. All series of DC UPS power supplies have been approved by China Classification Society.
