Power special UPS power supply mainly has the following characteristics
1, input, output fully isolated double transformation pure online design, high-speed static switching.
2, the intelligent digital control technology of three high-speed microcontrollers and programmable logic devices is used to achieve circuit control, parameter setting, operation management, advanced self-test and self-detection functions, which can self-test and fault analysis of all independent circuit connections on the circuit board.
3, Highly efficient IGBT (Insulated Gate Bipolar Translator) inverter technology, the sixth generation IGBT module device has lower saturation voltage drop, higher efficiency of the inverter, better impact resistance, higher reliability, fully meet the jump from 0 to 100% load, Without switching to bypass.
4, humanized large screen touch screen LCD Chinese and English display, intuitive LED status indication, workflow status indication at a glance.
5, with input and output over and under voltage protection, input surge protection, phase sequence protection, output overload and short circuit protection, high temperature protection and other perfect system protection and alarm functions.
6, optional input harmonic filter or 12-pulse rectifier, can effectively suppress the input harmonic pollution, improve the UPS input power factor, reduce the interference of high order harmonics to the control system.
7, advanced intelligent detection function:
The microprocessor of the system detects all power supply status, circuit breaker status, fuse status and all circuit working status online from time to time, and immediately protects and alerts the administrator if there is a fault.
8, the UPS DC input is directly connected to the DC screen bus bar through the check diode, the UPS itself can be without charging and battery components, because the DC screen in the power system station is responsible for maintenance, reliability is greatly improved.
9, industrial UPS design, in the wiring, power distribution, color code, process, safety protection and other aspects of the use of power industry specifications and standards. With power frequency, dual conversion, pure online, zero interruption, dual isolation and other features, the UPS with automatic bypass and manual maintenance bypass, improve the availability of UPS system.
10, the appearance size of the power special UPS panel is fully designed with reference to the power standard panel cabinet, the number and capacity of the output feeder circuit, etc., can be designed and manufactured in full accordance with user requirements.
11. In order to improve the safe power supply capacity of the power supply system and strengthen the safety and quality of the power supply under the fault/maintenance bypass operation mode, the isolation regulator is added on the bypass, and the bypass circuit can be selected as 220V or 380V two-wire system.
12, the output switch and feeder switch are generally with alarm contacts, failure to provide alarm signals to DCS and monitoring system.
