MATelec HydroWHIZ FPC-63343-S18.5 Mild Steel IP56 Inner Door 3PH 18.5kW Soft Start Triple Pump Controller

The FPC-63343-S18.5 brings 18.5kW soft-start capability to each of three pump outputs on a three-phase 400Vac HydroWHIZ controller. Adjustable soft start and stop operation provides controlled motor acceleration and deceleration while the HydroWHIZ system manages the pumps according to the selected control mode.

Its IP56-rated powder-coated mild steel enclosure includes an inner door and removable gland plate. Protection includes a pad-lockable mains power isolator switch, circuit breaker protected low-voltage control and input circuitry, individual pump isolation, contactor and thermal overload protection of pump motors, and DIN rail-mounted terminal connections. Visual strobe and mutable audible buzzer alarms are provided.

A 4–20mA input supports level, pressure or temperature transducers, while up to 8 digital 24Vdc inputs provide connections for low, stop, start, standby start and high float switches, pressure switches or thermostats, system enable/disable and low flow functions. Thermal switch inputs are available for each three-phase pump.

Duty, duty-assist and standby arrangements coordinate the three pumps, with adjustable duty sharing and alternation using bumpless transfer. Pump limiting restricts maximum flow or power requirements, while staging and destaging manages additional pump operation. Manual control, anti-seize, maximum run, pump cycle, no flow, feedback signal fault, pump overload, thermal switch and high/low level, pressure and temperature protection are provided. Temperature control includes sleep operation.

The system enable input enables or disables the system in automatic mode and can be used for auxiliary tank level protection. The colour touchscreen HMI provides time and date-stamped alarms, logged data, trend graphs and diagnostics. Standard interfaces include common fault, 0–10V analogue output mirroring the analogue input and Modbus RTU Serial RS485 for SCADA.
