Four New High Power DC Output SSRs

Crydom's D1D and D2D series of FET output DC Solid State relays formerly rated up to 40 A at 100 Vdc and 12 A at 200 Vdc, now includes new models rated at 60, 80 and 100 A at 100 Vdc, as well as 40 A at 200 Vdc. The new models which are offered in the industry standard "hockey puck" SSR package, adds to Crydom's present offer which includes the D06 rated to 100 A at 60 Vdc, D2D & D4D series rated to 12 A and D5D models rated to 10 A at 200, 400 and 500 Vdc, respectively.

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

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