Being ‘switchable’ allows the installer to simply select the output voltage to either 13.8V dc or 27.6V dc when installing the PSU by operating a PCB switch. When in ‘12V Mode’ it will charge a single 12V battery, and when in ‘24V Mode’ it will charge two in series. Offering both 12V and 24V dc minimises stock for the installer whilst covering power for a range of applications.

The models are currently available in 3 power variants,13.8V dc 8A / 27.6V dc 4A G1224-84 range, 13.8V dc 6A / 27.6V dc 3A G1224-63 range and 13.8V dc 4A / 27.6V dc 2A G1224-42 range.

All models possess a mains fail relay output and an independent ancillary relay that can be used for applications such as a fire door release. Other key features include switchable 13.8V / 27.6V dc output available in 3 power variants, energy efficient switch-mode technology which reduces running costs and extends lifespan, mains fail relay output, independent ancillary relay and a 3 year manufacturer’s warranty.
