Solid-state relays from a dependable source

Hongfa's solid-state relay range includes models with control circuits that can be driven by low-voltage DC (3-32V) or AC (18-36 or 90-280V) at low wattages. Panel-mount single-pole types are available with AC outputs up to 100A at 530V and DC outputs including 100A at 30V and 12A at 500V. Three-phase panel-mounting models feature AC outputs up to 60A at 440V AC with the option of phase loss protection. Panel-mounting dual relay types - which include two complete and independent relays in a single package, each capable of handling AC loads up to 50A 440V - are also included, as are a selection of PCB devices with AC outputs up to 5A 280V and DC outputs of 2A 100V. All models are fully RoHS-compliant.

Simon Dugdale, Applications Engineer at Hawco, comments: "Solid-state relays can replace electromechanical relays or contactors in many applications. With no moving mechanical parts to wear out or arcing contacts to deteriorate, they are extremely reliable with a very long service life."

Typical applications include: heater controls; food equipment; industrial lighting; fire and security systems; dispensing and vending machines; production equipment; traffic control equipment; medical devices; instrumentation systems; motor control panels; and manufacturing machinery.
