Mini desk-top UPS provides a 12VDC output in the event of an AC mains failure

Powersolve has introduced a desk-top 'mini' uninterruptable power supply (UPS) that provides a 12VDC output in the event of an AC mains failure. The PUPS22-12 works from a 12VDC input using an AC-DC adaptor such as the company's ESA36-12 and simply plugs in between the adaptor and the load. The PUPS22-12 is seen as ideal for powering networking devices such as routers and other low-power devices. The UPS incorporates three 3.7V Lithium batteries to provide an output capacity of 22.2W hours and a maximum output current of 2A. Charging is via a constant current / constant voltage, trickle charge battery management system. Features include discharge voltage protection and protection against charging over-voltage and input over-current. LEDs indicate charging and charged states. Input is via a 5.5mm x 2.1mm socket while output is via a 5.5mm x 2.5mm socket which will suit most applications. The PUPS22-12 measures 56 x 39 x 26mm and weighs in at 198g, says the company.
