MATelec HydroWHIZ FPC-63121-B Mild Steel 1.5 kW Variable Speed Single Pump Controller

Managing single-pump water transfer, stormwater pump-out and sewage applications, the HydroWHIZ FPC-63121-B provides variable-speed regulation with level, pressure and temperature operating modes. The system utilises single-phase 230 Vac input to generate three-phase 230 Vac output, with a 1.5 kW VSD rating reducing excessive current draw during pump starting and stopping.

Control logic allows selection between level, pressure or temperature modes, with speed adjusted according to system demand. Sleep Assist Boost and Pipe Fill reduce pump cycling and gently build pipe pressure during startup. Proportional speed control responds to level or temperature changes, while PID control maintains steady pressure.

The IP44 mild steel cabinet includes integral ventilation, a thermostatically controlled fan and removable gland plate. Interfaces include a colour touchscreen HMI with comprehensive diagnostics, pump circuit breakers and a padlockable isolator. A volt-free common fault relay provides BMS signalling, and Modbus RTU RS485 supports SCADA integration.

Configurable protection includes 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

• Pipe Fill gently builds pipe pressure during startup
• Thermostatically controlled fan provides enclosure ventilation
• Colour touchscreen HMI for monitoring, diagnostics and alarm logging
• Circuit breaker protected low-voltage control and input circuitry
• Padlockable mains power isolator switch allows the incoming power supply to be physically isolated during servicing and maintenance
• Modbus RTU RS485 communication protocols for SCADA integration
• Sleep Assist Speed Minimise gradually reduces pump speed to help the system enter sleep sooner
