MATelec HydroWHIZ FPC-63120-A Mild Steel Three Phase 0.75 kW Variable Speed Single Pump Controller

Providing single-pump variable-speed control for water transfer, stormwater and sewage pump-out applications, the HydroWHIZ FPC-63120-A operates with level, pressure and temperature control modes. Its 0.75 kW VSD rating runs from a three-phase 400 Vac supply, adjusting motor speed to match system demand.

Proportional speed control adjusts motor output for level or temperature applications, while PID control responds to pressure changes. Pressure-control algorithms include Sleep Assist Boost and Pipe Fill to reduce pump cycling and gently build pipe pressure during startup. Pumps are started and stopped in sequence to reduce excessive current draw and minimise water surge or hammer during changes in demand.

Housed in an IP44-rated powder-coated mild steel enclosure with integral ventilation, thermostatically controlled fan and removable gland plate, the panel includes pump circuit breakers, a padlockable mains isolator and a colour touchscreen HMI. The touchscreen provides system and individual pump status, operating modes, logged information, historical faults, run hours, pump starts, trend graphs and diagnostic functions. A volt-free common fault relay provides BMS signalling, and Modbus RTU RS485 supports SCADA integration.

Configurable protection functions include high and low level, pressure or temperature limits, no-flow and feedback-signal fault protection. VSD and system protection functions monitor operating conditions and provide configurable responses to faults such as overload, pressure, level, temperature, no-flow and feedback-signal conditions.

Features

• Pipe Fill gently builds pipe pressure during startup
• External padlockable mains isolator switch allows the incoming power supply to be physically isolated during servicing and maintenance
• Sleep Assist Speed Minimise gradually reduces pump speed to help the system enter sleep sooner
• Configurable low-pressure and no-flow protection
• 4-20mA analogue input compatible with level, pressure or temperature transducers
• Up to eight 24Vdc digital inputs for backup float switches, pressure switches or thermostats
• Pump anti-seize protection runs pumps periodically during low use to help prevent seizing
