Sensata | Crydom Solid-State Relay, 4 to 15V DC Control Voltage Range, 0.15 to 20A Load Current Range - TD2420Q

Need a switch that turn your machinery on and off without a hitch? Pick this solid-state relay from Sensata | Crydom. As the component has no moving parts, there's minimal wear for improved durability. The unit's SCR output gives it the muscle to handle heavy industrial loads. A snubber circuit design reduces voltage amplitudes and increases to curb power dissipation for more energy-efficient operation. You'll find this device useful for medical equipment, robotics and data acquisition systems.

• Wide operating temperature range between -40°C and +80°C for use in challenging conditions
• Broad control voltage range between 4 and 15V DC for use with numerous applications
• Light weight of 109g to place minimal strain on your equipment

What are the benefits of zero-cross switching?

This type of switching activates an application when the AC source reaches the zero-voltage point, which helps to boost efficiency and reduce noise.

How large is this SSR?

Thanks to its compact dimensions of 58.4 (L) x 21.6 (H) x 45.7mm (D), it's a sure fit for tight setups.
