Product Description

Overview
The ABB HiPerGuard MV UPS is a high-performance high-efficiency UPS system that ensures protection
from power quality events, enabling the continuous conditioned power supply to sensitive and critical
loads.
Based on the ZISC (Impedance Isolated Static Converter) architecture, the HiPerGuard MV UPS uses a
special coupling reactor combined with PEBB120 inverter modules to interface from the utility to the
load. The reactor acts as a barrier, preventing grid disturbances to reach the load and improves the
power factor seen from the grid side.
It is used to protect sensitive loads from the full spectrum of utility voltage events and combined with a
wide range of energy storage solutions ABB's ZISC provides autonomies from seconds to many minutes.
The equipment is connected to the medium-voltage network through the MV switchgear. The input
breaker connects the power supply to the MV UPS, which also has an active role in the normal operation.
The output breaker connects the MV UPS to the load, and a bypass breaker is connected between the
whole MV UPS system, as shown in the single line diagram.
