UPS Uninterruptible Power Supply system

Description

CYU series UPS adopts high performance DSP microprocessor real-time closed-loop control work for UPS, directly involved in the internal control of the important parameters, makes the UPS is in the best working condition all the time, greatly improving the UPS every performance of the machine.


Main Features

1. High level battery reliability:

  • Automatic battery test

  • Battery care, Battery life span can be increased approximately by 20% more

2. Back feed protection: to avoid energy feeding back into the mains supply

3. Bypass may be deactivated to allow operation as a frequency converter (at 50 or 60 Hz), or as stabiliser

4. Easy to maintain (front access)

5. Reliable, filtered, stabilised and regpated sine wave output (double on-line concersion technology VFI according to EN50091-3 specifications) with filters for atmospheric disturbance suppression

6. High reliability: IGBT technology, fpl microprocessor control with no-break static and manual bypass

7. High level diagnostics: event log with 128 messages, states, measurements and alarms-available from the built-in LCD in several languages

8. The UPS may be configured with the RS232 serial port (flash upgradable )
