Relay & อุปกรณ์จ่ายไฟ
Solid state relays and power switching devices for industrial control panels. Solid state relays switch AC loads with no moving parts — no contact wear, silent operation, and far longer service life than mechanical relays under frequent switching. Zero-crossing types reduce electrical noise, and photoelectric isolation keeps control and load circuits separate. Suited to heater control, temperature systems, and any application cycling too often for mechanical contacts. Prices exclude VAT.
