Product Description
Outline of the GP31 series UPS

Frequency double-conversion online GP31 series is an intelligent frequency on-line UPS for the Chinese power grid environment and load system in order to meet the high reliability power requirements well-designed.GP31 system is on-line double conversion topology architecture design, completely eliminates all kinds of interference from the power grid, so that the output of the UPS to frequency stabilization, filter out noise, interference from power fluctuations, low distortion of pure sine wave power.The GP31 series is the latest international hardware, the most advanced software combines crystallization, to provide highly reliable power protection for today's centralized services room, network management and computing centers of large medical equipment, production control equipment. Capacity from 6KVA to 40KVA.

Key Features

1. High reliability design concept
GP31 intelligent frequency on-line UPS uses good DSP control technology and perfect protection circuit stability, power devices using imported 1GBT module design, with superior overload and impact resistance capability, built-in output isolation transformer anti-interference ability, load compatibility is good.
Wide range of applications
Wide voltage input range of 304 ~ 456V avoid frequent switching to battery power, while extending the battery life and reduce battery maintenance times.This machine designed wide input frequency range to ensure in the case of absence of electricity,access to fuel generators can stable work.
Comprehensive and reliable protection function
This series UPS has turned self-diagnosis function, to avoid the risk of failure due to UPS risks that may arise, having an AC input over / under voltage protection, output overload, short circuit protection, inverter over-temperature protection. Battery voltage warning / protection, greatly ensure the exchange of stability, reliability, overload at 110% / 125% / 150% overload can Maintain 10min / 1min / 300ms.
