Using true power sensing rather than current alone, the PFR-1550V detects overloads, jams, obstructions, sudden load changes, loss of load, missing tools, and misplaced parts the instant they develop — responding faster than conventional current-based protection and triggering alarms or automatic shutdowns before equipment damage occurs. The included PH-3A Power Cell Transducer is purpose-built for machine tool and VFD motor monitoring, delivering ultra-fast response to spindle load changes, tool breakage, and overload conditions with no PTs or CTs to install — making it the ideal sensing partner for fast-changing, variable frequency environments. With a single set point configurable for either a high or low trip condition, the PFR-1550V provides straightforward, reliable protection precisely tuned to the application — whether monitoring conveyors, mixers, material handling equipment, CNC spindles, or other VFD-driven industrial motors where fast, dependable protection without complexity is the priority.\u003cbr\u003e\u003c\/p\u003e","brand":"Load Controls LLC","offers":[{"title":"Default Title","offer_id":48893823058155,"sku":"PFR-1550V Single Set Point W\/PH3A","price":1615.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0815\/4474\/1099\/files\/PFR-1550VSingleSetPointWPH3A_66076594-de8c-4e4f-a398-b3c7b95007b4.png?v=1782901218","url":"https:\/\/loadcontrols.com\/products\/single-set-point-load-control-with-ph-3a-power-cell-monitor-pfr-1550v-w-ph3a","provider":"Load Controls ","version":"1.0","type":"link"}
