GPS®-501 Three-phase uninterruptible power supply with Type LCD function

Quietly with IGBT device control. Three-phase uninterruptible power supply GPS®-501 type, which looks bright even in the dark with advanced LCDs, uses LCD for display and allows UPS to operate even in dark installations. It’s a high-performance, high-performance product that you can check.

Overview

This product is an IGBT-type UPS manufactured using a state-of-the-art power  element in a non-pure synchronous cutting  method, and the rectifier on the input side consists of 6 Pulse or 12 Pulse. The inverter configuration adopts the angular phase control method so that the load ratio of each phase can be adjusted, and the operating frequency is 20㎑, so there is very little noise during operation, and it is designed to have various protection functions. When the inverter stops operating, the output power is made to power the load with a non-stop  bypass power, which is detected by the micro-processor and stored automatically. In addition, the operation status of each  part can be  easily read by displaying the operation status in Logic, and at the same time, the LCD can check voltage, current, frequency, DC voltage, etc. with one-touch method, making it a very easy-to-operate UPS.

Operation’s description

When Main-2
is supplied – Main-2 supplies AC power to the rectifier with commercial power, and the rectifier converts the net to automatically charge the battery in case of a power failure. The  inverter part consists of the  IGBT Full Bridge method and detects and controls each phase, so there is no voltage deviation in the unbalance load.

Main-1
Supply – Bypass Power Supply is used as a load protection reserve during initial operation and during equipment failure and is not eligible for power failure.

EMERGENCY S/W
– This device is added to maintain the UPS without disconnecting load power in the  event of an inverter failure.

In the case Overload and inverter failure – In the event of an overload, the inverter stops automatically and automatically cuts off without turning off. The  auto-cutter is cut to Main1 and automatically restored to the inverter when the overload condition is released.

Display Channel
– It displays all the operation-status through VFD and switches between Invertor On/OFF mode.
– Automatic rectifier-part
– Synchronous switching part
– Battery part
– Three-phase inverter part
– VFD Display part
– Maintenance part
