SSC21
12V DC Power Contactors
The SSC21-100, SSC-150, and SSC200 are part of InPower’s second-generation family of high current solid-state DC contactors.These single-channel power switches are rated at a continuous current rating of 100, 150, and 200 amps respectively. Low on-resistance solid-state switches and high current flyback diodes provide not only outstanding surge current capability for starting high in-rush current loads but also maximum voltage spike suppression for loads.
