Description

VPT’s SVR Series of DC-DC converters deliver a qualified power solution for your next LEO, MEO, GEO, deep space, and launch programs. Rad hard, qualified to MIL-PRF-38534 Class K on DLA SMDs, and designed for TOR compliance, these modules help you get your system off the ground fast. View VPT’s space program heritage.

Combine our extensive family of DC-DC converters for space with VPT’s point of load converters for space and EMI filters for space to create a light weight, extremely efficient, space-qualified distributed power system.

This 8A point of load converter delivers extremely efficient, non-isolated, power at your load.
