MVDC Circuit Breakers Interrupt Full Load Currents in Microseconds

April 28, 2013 by Jeff Shepard

Diversified Technologies, Inc. has introduced compact, solid-state medium voltage DC (MVDC) circuit breakers for use in commercial micro-grids and military dc power distribution systems. DTI PowerMod™ Solid-State MVDC Circuit Breaker Modules open in 3 kV) in the event of a fault. Featuring > 99.7% switching efficiency, these modules can also switch power around a fault for high uptime applications such as maintaining power levels in a micro grid.

Capable of supporting a range of alternative sources and storage systems, including wind- and solar-power, battery storage, and flywheels, with a range of voltages, frequencies, and power levels, DTI PowerMod Solid-State MVDC Circuit Breaker Modules operate fully-on or -off. At 10 kV, a 50A dc module measures 12" x 5" x 3" and is stackable for switching up to 100 kV.

DTI PowerModâ„¢ Solid-State MVDC Circuit Breakers are priced from $9,995.00 and provide > 1 million hours predicted reliability per MIL-HDBK-217F.
