Sensata announces Crydom DR45 Series solid state relay


Next >>

Sensata Technologies (ST) announced it has added the Crydom DR45 Series solid state relay (SSR) to its NOVA22 family for use in industrial machinery, HVAC&R and railway vehicles. This DIN rail mount SSR offers power density up to 60 Amps at 40°C in a 45mm package and is a solid state relay capable of accepting output wires up to 3 AWG with an IP20 protection rating.

The SSR has integrated heat sinks designed to provide the appropriate thermal resistance for the application without the need for calculations. Cage clamp output connections provide a finger touch-safe IP20 protection rating and allow for installation of large wires directly to the SSR, without the need for lug terminals or other accessories. Input connection options include standard ‘screw’ or ‘spring’ cage terminals for design into a variety of applications.

Designed for thermal performance, the DR45 solid state relay also features optional built-in overvoltage protection, contactor configurations and either AC or DC control. The SSR is available in an AC output voltage range of 48 to 600 VAC and holds C-UL-US, VDE, CE and RoHS approvals.
