UPS

on-line interactive UPS-----CR series (UPS)

it has AVR function;
it can protect against overload,short-circuit and it starts up gradually;
it is able to connect an external battery and work for a long time;
it is suitable for impactive loads,such as lighting, TV set,fans,refrigerator and air-conditioning etc.
Three-phase UPS

*True intelligent UPS with the mini-processor control.
*True online UPS, pure sine wave output.
* Using the latest power unit IGBT to make the UPS more efficient and reliable.
*When three phases output on 100% unbalanced load, operate continuously.
*Unique output short circuit protection, jump-free main switch.
* It is safe and reliable with the isolation transformer.
* Whole protection agai
OFFLINE UPS ——CR SERIES

online interactive ups

Ouyad new design series----on-line normal frequency UPS adopt on-line sine wave design. Completely controlled by CPU, the voltage and frequency of output sine wave is stable and reliable. It can be used for driving impactive loads, such as air-conditioning and refrigerator, and then enables the UPS work in the circumstance where the power supply is unstable and meet your most strict requirement.
