PRODUCT CHARACTERITICS

Intelligent human
-machine interface

large-size color touch screen makes human-machine operation more convenient.

Intelligent monitoring system

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.

Redundant design

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.

Long service life

Uses the battery of well-known brand, and the service life is up to 100,000 hours (1500 times).

High stability

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.

High reliability

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.
