FAQ
How much current can it supply?
1.5 A total at 24 VDC nominal. Each of the three power-limited outputs can supply up to 1.2 A; with all three equally loaded, the maximum is 500 mA per circuit.
What batteries does it hold?
The cabinet has space for two 12 V 12 Ah batteries. For larger standby capacity the VBC-001 battery cabinet is required.
Which faults does it report?
Two Form C relays, remote and local, transfer on AC input loss, low AC input voltage, loss of battery voltage, or a short on any DC output.
Can it be installed outdoors?
No. It is intended for indoor, dry use only.
