It runs off 230 VAC and is rated to switch approximately 1.5 A, enabling it to act as a high‑pressure cutoff or safety interlock in refrigeration, air‑conditioning, and other pressurized systems. As a PS3-series device with a fixed switch-point, the PS3-AJR provides repeatable operation at the moment the sensed pressure reaches the configured threshold, making it suitable for protecting compressors, condensers, and related equipment from overpressure without field adjustment. Typical applications include industrial HVAC refrigerant circuits and other systems where a robust, pre-set protection point is required; its Alco Controls lineage is recognized for durable performance in demanding environments.\u003c\/p\u003e\u003c\/div\u003e","brand":"ALCO","offers":[{"title":"New","offer_id":51657194537262,"sku":null,"price":232.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_261f8789-ad29-4752-b0a0-5fdfc70d1033.jpg?v=1769466741","url":"https:\/\/plgautomation.com\/products\/alco-controls-ps3-ajr-pressure-controller-switch","provider":"PLG Automation ","version":"1.0","type":"link"}
