Single Set Point Load Control with PH-3A Power Cell Monitor PFR-1550V W/PH3A

The PFR-1550V Single Set Point with PH-3A Power Cell brings together the fast response protection of the PFR-1550 and the ultra-fast true power sensing of the PH-3A — delivering a focused, high-sensitivity load control solution purpose-built for variable frequency drive applications where a single configurable trip point is all that's needed. 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.
