AJAX PSU 220VAC for HUB2 and HUB2+ Power Supply

The AJAX PSU 220VAC is a power supply unit for the AJAX HUB2 and HUB2+ alarm hubs. It belongs to the Alarm Systems category and sits in the Control Panels sub-group, which groups the central units that manage an AJAX wireless security system.
An alarm hub needs a stable power source to keep the system running. This 220VAC supply is intended to power the hub from a standard mains outlet rather than relying on other sources. Its place in the AJAX range makes it a natural companion to the HUB2 and HUB2+ units.
