Ajax 6V PSU | Power Supply Unit for Hub 2 & Hub 2 Plus | Low-Voltage External Battery Operation
Summary
The Ajax 6V PSU (type A) is an alternative power supply unit designed to enable Ajax hubs and range extenders to operate from 6V portable battery sources. This electronic board replaces the standard 110/230V power supply unit inside the device enclosure, allowing for extended autonomous operation in locations without mains electricity.
With the 6V PSU installed, an Ajax hub or range extender can operate on an external battery for up to 30 months without connecting to a facility’s power grid. Combined with Ajax wireless devices that operate on pre-installed batteries for 2 to 10 years, this solution enables complete 24/7 property monitoring and protection in facilities lacking stable electricity supply.
The 6V PSU (type A) is ideal for protecting summer houses during winter months, empty properties vulnerable to illegal occupation, warehouses with unstable power, and construction sites with valuable materials and equipment. Installation must be performed by a qualified electrician following general electrical safety rules.
