Transfer Panels
Technical Data Sheet
Full load rated
Bypass Breaker
¼ cycle transfer time including sensing
Automatic synchronizing with normal AC power
Automatic lockout provision for non-sync condition
Phase detector that:
- Disconnects the synchronization line from the inverter if the bypass frequency deviates from 60Hz by more than 2Hz
- Prevents high speed transfer if the system is not synchronized with the bypass line
AC ammeter and voltmeter
Automatic or manual transfer to bypass
Manual retransfer to inverter
Service switch c/w bypass isolation switch to enable servicing all parts of the UPS while maintaining the loads on bypass power
Mode of operation Indicators:
- Inverter available
- Bypass available
- Load on inverter
- Load on bypass
- Bypass out of sync
Terminals for connection of the inverter AC, bypass AC, load AV, and all UPS interconnected alarms
Front access to all equipment
Optional slow-speed transfer with 50 ms transfer break time to allow complete seperation of the inverter from power line interference.
