Two Set Point Load Control with PH-3A Power Cell Monitor PFR-1750V W/PH3A

The PFR-1750V Two Set Points with PH-3A Power Cell brings together the fast response protection of the PFR-1750 and the ultra-fast true power sensing of the PH-3A — delivering a complete, high-sensitivity load control solution purpose-built for variable frequency drive applications. Using true power sensing rather than current alone, the PFR-1750V 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 two independent set points configurable for either high or low trip conditions, the PFR-1750V gives engineers the flexibility to tailor protection precisely to their application — whether monitoring conveyors, mixers, material handling equipment, CNC spindles, or other VFD-driven industrial motors where fast, reliable protection is non-negotiable.
