Crydom Adds 4 New High Power DC Output SSRs

Crydom Inc. announced additions to its D1D and D2D series of FET output dc solid state relays formerly rated up to 40A at 100Vdc and 12A at 200Vdc, now includes new models rated at 60, 80 and 100A at 100Vdc, as well as 40A at 200Vdc.

The new models which are offered in the industry standard "hockey puck" SSR package, add to Crydom’s present offer which includes the D06 rated to 100A at 60VDC, D2D & D4D series rated to 12A and D5D models rated to 10A at 200, 400 and 500Vdc respectively.

The new D1D relays feature a low on-state resistance FET output capable of carrying 60, 80 or 100A when the SSR is mounted on an appropriately rated heat sink. Likewise, the new D2D40 features a similar FET design rated to 40A with appropriate heat sink. Control for these Crydom dc output SSRs is by a transformer isolated 3 to 32Vdc logic compatible input providing 2500Vac input to output isolation. The outputs are diode protected and specified to operate up to 1 kHz.

Crydom dc output SSRs are suitable for heating and lighting control as well as motor control in commercial, industrial, medical, aerospace, rail and automotive applications.
