NPM20
Intelligent High-frequency
DC Power Supply System
A brand new power supply system integrating digital control, protection and management to provide stable operating power for DC circuits.
NPM20 series intelligent high-frequency DC power supply system is mainly used in power grid, power generation and other fields. As a DC uninterrupted power supply for all automatic electric power systems, communication systems, remote execution systems, switch opening and closing, relay protection, automatic devices and signaling devices of high-voltage circuit breaker.
large-size color touch screen makes human-machine operation more convenient.
The system is equipped with RS485/RS232 communication interface and adheres to Modbus-RTU protocol, which can be accessed to the back-end system to realize intelligent monitoring.
High-frequency DC power supply module adopts N+1 redundant design and high-frequency resonant soft-switching technology, reducing the loss and extending the service life.
Uses the battery of well-known brand, and the service life is up to 100,000 hours (1500 times).
he rectifier module utilizes advanced soft-switching conversion technology and built-in CPU technology, with low voltage distortion, high efficiency, high accuracy of voltage and current stabilization and low ripple coefficient.
The charging module can be hot-swapped, which greatly reduces the average maintenance time, so that the device is able to monitor the insulation of the system in real time to ensure system and personal safety.
