iVS8 Series 4920 Watt Configurable AC-DC Power Supplies


The iVS8 series is a 3-phase AC input to DC output configurable power system consisting of a microprocessor-controlled PFC front end providing 14 individual 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 4,920 watts and with up to 42 isolated outputs, the iVS8 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.
