Main features

1. Wide input range

Large fluctuation range of mains voltage 285V-475V rectifier works normally to extend battery life

2. Output isolation transformer

The low-voltage terminal current has large harmonics, which has no effect on the input terminal and the power grid, and the zero-ground voltage is less than 1V

3. The inverter adopts three single-phase independent full-bridge architecture
Ensure the impact resistance of the whole system, strong overload capacity, allowing 100% imbalance of the three-phase load, and the three-phase voltage error is less than 1V

4. The battery is directly connected to the bus

Can absorb, voltage flicker/drop, motor load when the reverse current

5. Cold start

AC and DC can start UPS to meet the needs of emergency

6. Perfect man-machine communication scheme

Using large-screen touch LCD as the main display interface, the display content can be selected and set in Chinese/English, and the running status, operating procedures, data acquisition, fault detection, 256 pieces of historical records and other contents are clear at a glance.

7. Intelligent battery management function

Adopt rectifier/charger integrated design, according to the battery configuration capacity, through the operation interface to set the parameters, and the software automatically adjust the charging current, but also according to the grid security conditions set the battery automatic detection and charge/discharge interval time, extend the battery life

8. Rich communication function interface

Built-in RS232/RS485 communication port and a variety of dry contact signal interface, truly realize multi-purpose communication and remote monitoring

9. Complete protection function

It is equipped with a variety of system protection functions to detect and alarm abnormal states such as overvoltage, undervoltage, overcurrent, overload, short circuit, etc., and has reliable protection functions and strong environmental adaptability.
