Three Multi Dialog 60kVA UPS from Riello Galatrek have been chosen for the Cardiff branch of internet based banking operation ING Direct. Each UPS has its own 10 minute battery pack to provide protection from short duration mains failure and allow the roof top based 377kVA generator to start.
The Multi Dialog UPS are installed in parallel operation to provide N+1 redundancy. Should one of the UPS fail the other two systems can take over powering the installation, without any distruptions to the loads.
Each UPS was installed with an SNMP adapter to connect it to the ING Direct network using a TCP/IP port address. A wide range of UPS parameters can be monitored including load and battery performance for each and the combined power system.
