Desk-top mini DC UPS provides a 12VDC output
A desk-top mini UPS, from Powersolve, provides a 12VDC output in the event of an AC mains failure. The PUPS22-12 works from a 12VDC input using an AC-DC adapter such as Powersolve’s ESA36-12 and simply plugs in between the adaptor and the load. According to Powersolve, the UPS is suitable 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 5.5x2.1mm socket while output is via a 5.5x2.5mm socket which will suit most applications. The PUPS22-12 measures 56x39x26mm and weighs in at 198g.
