Sensata | Crydom Solid-State Relay, Zero-Cross Switching Type, 3 to 32V DC Control Voltage Range - CMR48 Series - CMRD4855

For reliable switching of heavy-duty loads, make the change to this solid-state relay from Sensata | Crydom. A hefty current rating of 55A means it's just the thing for heavy-duty applications. An integrated heatsink ensures the unit keeps its cool for efficient performance. It's a zero-cross switching type that turns on when the voltage is near zero to minimise electrical noise. This device has your back in applications such as robotics systems and medical equipment.

Features & Benefits

• Performs reliably at temperatures between -40°C and +80°C for use in demanding environments
• Green LED indicator lets you know the input status at a glance
• Clips onto a DIN rail for installation in a snap
• Screw terminals for a secure electrical connection without the need for special tools
• Wide operating voltage range of 48 to 530V AC for versatility

How large is this SSR?

This SSR has compact dimensions of 109.2 (L) x 76.2 (W) x 44.5mm (D). This helps to maximise space on a crowded DIN rail.
