Industrial Uninterruptible Power Supply Systems
5kVA to 100kVA
The E20 UPS system is designed as a cost effective industrial product and utilises the latest in power conversion switching technology to provide all types of critical loads with absolute power security and isolation from power line disturbances and interruptions.
This active-on-line UPS system provides the critical load at all times with stabilised voltage and frequency from its high performance PWM inverter. The modular and flexible design makes use of IGBT inverter, rectifier and static switch modules which enable us to configure systems to suit the individual needs of customers.
The E20 UPS system is provided with digital or analogue metering and a mimic panel is provided to show the operational status and alarm conditions. Serial interfaces are available for remote monitoring of the UPS and, upon request, supervisory software is available for monitoring by computer.
