22.5mm DIN Rail Solid State Relays handle up to 95A

Crydom announced the new NOVA22 ac and dc output solid-state relays. NOVA22 solid-state relays (SSRs) are available in both DIN rail (DR22 series) and Panel mount (PM22 series) packages. NOVA22 solid-state relays feature: DIN rail models rated up to 35A and panel mount models rated up to 95A; 22.5mm wide package; 4- to 32-Vdc, 90- to 280-Vac/dc or 18- to 52-Vac/dc input control options; Relay or contactor layout configuration; Innovative "Elevator" screw for easy connection of ring terminals; LED input indicator; Overvoltage protection; Zero voltage or instantaneous turn-on output; 100kA Short Circuit Current Rating; and Maximum I2t value of 8320 A2sec.

These features make NOVA22 SSRs unique in the market, outperforming competing products on each front with a broader working temperature range (-40 to +80 degrees C), and higher resistance to surge current (1290A x 20 msec). High I2t models (8320 A2S) allow use of the solid state relay in conjunction with circuit breakers instead of fuses allowing short circuit protection in Type 2 Coordination per IEC 60947-4-1. Contactor configuration models include a plug-in connector for the control input, available in either standard “screw” or “spring” terminals.

The DR22 series is available in either ac output voltage (48 to 600Vac) or dc output voltage (1 to 200Vdc). Current rating at standard 40 degrees C is 20A, 30A and 35A (only for ac output) and high I2t value (8320 A2S), making NOVA22 the only 22.5mm DIN rail mount solid state relay with 35A at 40 degrees C.

The PM22 series is available with ac output voltage (48- to 600-Vac). Current ratings include 25A, 50A and 95A and high I2t value (8320 A2S) making NOVA22 the only 22.5mm panel-mount solid-state relay with 95Amps on the market. Crydom also offers the new HSP-7 thermal pad available for purchase as an accessory or already assembled on the solid state relay to facilitate installation.
