SOLA 4000 - PCB Description
1 UPS Control Logic
1.4 Bypass
The bypass static switch control logic consists of two PCBs.
IF/PS - S Bypass monitoring and power supply
•bypass electronic power supply
•mains voltage sensing
CPHC16 - S Bypass control
•switching control of the static bypass switch SSB
•interface with the inverter or multiple inverters
•mains frequency monitoring
•mains voltage and phase rotation monitoring
•generation of synchronisation signal
•interface with multiple static bypasses
•UPS output voltage monitoring
•majority control for multiple static bypasses (parallel and hot standby systems)
•synchronisation monitor: mains - UPS output
