Special electric on-line UPS
Special electric on-line UPS is a new energy specially designed for power station and converting station,an online, zero delay the conversion function,mainly applied in the place where the load on a high demand.such as electric telemechanics, RTU, DCS system, the electric carrier, monitor etc.
Principle:
when city electricity normally, single-phase 220V AC(or three-phase 380V) through isolation,provides power for inverter; if AC input failure,l the power system of direct passing, remember to keep the change and to swim against the power supply,then past the output from the power supply to provide power for important load.if DC screen electricity failure,AC input still provide power;if the inverter failure,then the static switch turn sideway to provide power.
Features
using Standard Screen Cabinet with Power Design
Zero-delay conversion between utility electric Supply / DC inverter power,inverter bypass ≤4ms
AC input,DC input and AC continuous output between complete isolation
Using DSP digital control technology, intelligent detection and monitoring capabilities
High-speed IGBT drive inverter
Passive monitoring of contacts and RS232/485.
With overvoltage, low voltage, overcurrent, short circuit protection functions
Big-screen English LCD display interface
