iMP8 Series 1000–1200 Watt Configurable AC-DC Power Supplies

iMP8
 

The iMP8 series is an AC input to DC output configurable power system consisting of a microprocessor-controlled PFC front end providing six slots that accept intelligent DC-DC converter modules with single, dual or triple outputs ranging from 2 V to 60 V. Single output modules come in four power ranges that can be mixed and matched and connected in parallel or series to obtain thousands of output combinations customized to any application. User-configurable functions include current limit and output sequencing, as well as input and output OK signals and indicators. Capable of delivering up to 1,200 watts and with up to 18 isolated outputs, the iMP8 series carries full medical safety approvals and is an extremely flexible and versatile multi-output power solution.

These digitally controlled power supplies feature a PMBus™-compliant I2C serial interface that enables parameters such as the voltage, current limit and enable/inhibit status of individual outputs to be programmed via an intuitive user GUI. The serial interface also allows remote monitoring of voltage, current and temperature.
