The Slimpack is an AC/DC converter and battery charger/rectifier for stand-alone use. It is a switchmode power supply designed for battery charging and supplying high quality DC power to telecom equipment and similar applications. Switchmode technology with soft switching and high switching frequency is used to minimize volume and weight and to obtain fast output voltage regulation. The module accepts large variations in the input voltage and draws sinusoidal current with a soft start power-up. The controller card contains a mains sense circuit, battery contactor, reverse battery polarity protection and battery current limit circuit. Modern, yet well-proven technology makes the Slimpack a compact and reliable power supply. In addition, a wide range of features are integrated.

Typical applications:

The rectifier is used for all DC power requirements where a N+1 solution is not required.
