Practical Control Solutions has released their CP3 range of three phase solid relay assemblies. These assemblies are designed to replace electromechanical contactors in applications involving frequent switching such as ovens, kilns, plastic extruders, dryers, and printing and packaging equipment.
With no moving parts within the switch these assemblies offer a much longer service life than their electromechanical counterparts, as well as silent and vibration free operation.
The CP3 assembly is comprised of an extruded aluminium heatsink, solid state relays, cooling fan, over temperature switch, acrylic cover and optional protection fuses. Standard current ranges are 45, 70, 95 and 120 amps.
Available control signals are 4-32V DC or 90-280V AC/DC.
