Ordering information

UPS function supports two VRLA batteries up to 24Ah capacity

Up to two 24Ah VRLA batteries can be connected to the battery terminals of the power supply PCB. This power supply will automatically float-charge the battery to capacity, providing continuous uninterrupted power from the battery if mains power is unavailable.

Batteries are not included. This unit can be used with or without batteries fitted.

Mains failure signalling

If the mains-input power is not detected for approximately 30 seconds, the mains-fail relay will change-over. The delay helps prevent false triggering during common power fluctuations within the national grid. The clean normally open-circuit (N/O) & normally-closed-circuit (N/C) relay contacts can be used to switch or signal other systems.

Low-battery signalling

Should the connected VRLA battery be nearing depletion, the Low Vol relay will change-over. The clean N/O & N/C relay contacts can be used to switch or signal other systems.

Aluminium chassis

Precision-made from aluminium, this mounting plate is ideal for installing within existing equipment with the ability to secure as required.

Input 230V AC @ 50Hz (+/- 10%)

These power supplies accept a standard mains voltage input of 230V AC at 50Hz (+/- 10%).
