The Fuji FRN100F1S-4DY is a FRENIC-ECO Pump (F1-DY) variable frequency drive rated for 100 HP on a 460 V three-phase supply. It's a current-production unit from Fuji's dedicated pump control series, meaning it ships with pump-specific features like flow compensation, multi-pump sequencing, and sleep/wake functions baked into the firmware — no separate PID controller or relay logic needed for basic pressure/level control.
Deployment context
This is a panel-mount drive sized for a 100 HP motor on a 460 V three-phase feed — think a 75 kW pump, a large fan, or a compressor. The FRENIC-ECO Pump firmware handles the control loop for constant-pressure or constant-level systems out of the box, so an integrator can skip programming a separate PID. Expect to land three power wires and a motor cable; the control terminals accept 24 VDC digital inputs and analog signals for setpoint feedback.
