We have found applications for various forms of power supplies and surge protection. Different supplies are available to power LEDs in buildings or control panels, motor speed control, relay control, LED strip lightingand general low/high current customer needs. Most of the power supplies use transformer accessory voltage with input up to 22 VAC. An onboard potentiometer is provided on the variable versions to set the specific voltage output. Alternate output voltages are available by requestto support your application. Still got questions? Drop me an email.
