DC solid-state power controllers to replace conventional circuit breakers

Teledyne Relays in Hawthorne, Calif., is introducing a series of DC solid-state power controllers to replace conventional electromechanical circuit breakers to reduce component count, system weight, and cost, while increasing system reliability. The PC 150 solid-state power controllers switch, monitor, report status, and provide circuit protection for circuits from 2 to 25 amps within the voltage limits and conditions in MIL-STD-1275, company officials say. The devices feature current flow status, load voltage status, trip status signals, and built-in transient suppression. The PC 150 power controllers meet the requirements of computer-controlled power distribution systems by offering the control options of solid-state technology while retaining protection of traditional circuit breakers. Additional design features include surge-tolerant short-circuit protection and optical isolation. For more information contact Teledyne Relays online at www.teledynerelays.com.
