Sensitron is capable of supplying custom design Solid State Power Products and Remote Power Controllers  that satisfy many unique electrical and mechanical requirements. The Solid State Power Controller (SSPC) and Remote Power Controllers (RPCs) are microcontroller based Solid State Circuit Breakers designed to be used in varous hi-reliability applications. Sensitron's line of Solid State Relays can be used wherever hi-reliability is a necessity but non-hermetic pricing is a project requirement. Both standard and custom products are available and can include features such as photovoltaic optical isolation and power MOSFET output, providing extremely low on-resistance.
