It is powered from 120 VAC, 50\/60 Hz, and provides relay contacts rated for 10 A resistive at 115 VAC, with the sensing input able to accept 120\/240\/480 VAC for single- or three-phase systems. The PS-127A uses a locking-bushing potentiometer to set the switching point, includes a small differential of about 5% between turn-on and turn-off to prevent chatter, and a built-in LED indicates when the relay is energized; the sensing terminals tolerate up to 600 V overvoltage. Operating temperature range is -10°F to 135°F (-23°C to 57°C).\u003c\/p\u003e\u003c\/div\u003e","brand":"Autotech","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51660395839790,"sku":null,"price":1298.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_c442793e-46e3-477d-b58c-64eb75cd359f.jpg?v=1769537315","url":"https:\/\/plgautomation.com\/products\/autotech-corporation-ps-127a-zero-speed-switch","provider":"PLG Automation ","version":"1.0","type":"link"}
