MATelec HydroWHIZ FPC-63120-F Mild Steel Three Phase 5.5 kW Variable Speed Single Pump Controller

For single-pump speed regulation in water transfer, stormwater and sewage applications, the HydroWHIZ FPC-63120-F offers variable-speed control with level, pressure and temperature operating modes. Its 5.5 kW VSD rating runs from a three-phase 400 Vac supply, reducing excessive current draw during pump starting and stopping.

The integrated control module features advanced algorithms that regulate the pump using configurable proportional and PID parameters. Pressure-control functions include jacking pump support, Pipe Fill and Sleep Assist Speed Minimise, with proportional speed control for level or temperature and PID control for pressure ensuring stability. 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, historical alarms and trend graphs. A volt-free common fault relay provides BMS signalling, and Modbus RTU RS485 supports SCADA integration.

Protection features include high and low limits, no-flow and feedback-signal faults. 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

• Individual pump circuit breaker protection helps isolate a fault with an individual pump or cable
• 4-20mA analogue input accepts hydrostatic level or pressure transducers
• Pipe Fill gently builds pipe pressure during startup
• Volt-free common fault relay terminal provides remote signalling of active controller alarms
• Sleep Assist Speed Minimise gradually reduces pump speed to help the system enter sleep sooner
• Eight auxiliary 24Vdc digital inputs for backup float switches and pressure switches
• Serial RS485 terminal block supporting Modbus RTU for SCADA integration
