The new 'switchable' 12V dc / 24V dc switch mode range of power supplies has been designed for access control, CCTV and general purpose applications that require the use of a standby battery. 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 relay. There are two enclosures available to house either 12V 7Ah or 17Ah batteries. The products use energy efficient switch mode technology and therefore have a universal mains supply input (90-264V ac).
On installation the units can be setup to provide either 13.8V or 27.6V dc by a simple PCB selection switch. They are available in three power variants with multi-fused output models if required.
Three power variants available are:
