1 、 Emergency power supply: when the power supply is interrupted or abnormal, the 220V/380V 50HZ AC can be automatically supplied. Standard type is 90 minutes, according to customer needs can be long, short, pure sine wave output.
2, Automatic switching, unattended. When the power grid is in power, it is in static state without noise. When there is no city power, it is less than 55DB, and the switching time between the power supply and the EPS power supply is 0.1 to 0.25S (when the fast switching device is added, it can reach 10ms or less).
3 、 High reliability, strong carrying capacity and stable performance. The company adopts advanced technology and redundant design, centralized control by CPU, product selection of high quality components, stable performance, high reliability. Adopting SPWM high frequency inverter technology, the power supply quality is high, which is suitable for equipment with inductive, capacitive and comprehensive load, such as elevators, pumps, fans, office automation equipment, emergency lighting and so on.
4,For some large power facilities, such as: fire pump, air blower, EPS can be directly connected with the motor starting, then enter the normal operation state, can save a motor soft starter and control box and other equipment.
5 、Protection and improvement, with excellent output overload protection, short-circuit protection, battery reverse protection, over discharge protection, anti misuse ability.
6 、 Friendly interface, LCD display working state, city power, voltage, output voltage, battery voltage, current, frequency, load rate, fault and other information. And there are sound and light fault alarm, indicating the type of fault and fire linkage.
