MATelec HydroWHIZ FPC-63120-G Mild Steel Three Phase 7.5 kW Variable Speed Single Pump Controller

Managing single-pump water transfer, stormwater pump-out and sewage applications, the HydroWHIZ FPC-63120-G provides variable-speed regulation with level, pressure and temperature operating modes. Its 7.5 kW VSD rating runs from a three-phase 400 Vac supply, with pump speed adjusted according to system demand.

Control logic allows selection between level, pressure or temperature modes, adjusting speed precisely to match demand. In pressure-control modes, Pipe Fill builds line pressure, while jacking pump control brings Pump 1 out of sleep first, with the main pumps starting when it can no longer keep up with demand. Proportional speed control responds to level or temperature changes, with PID control maintaining steady pressure. Pumps are started and stopped in sequence to reduce excessive current draw and minimise water surge or hammer.

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

Configurable protection covers 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. Manual operation is available for both the system and individual pumps, with a 10-minute timeout returning the controller to automatic operation.

Features

• Sleep Assist Speed Minimise gradually reduces pump speed to help the system enter sleep sooner
• Circuit breaker protected low-voltage control and input circuitry
• Dedicated BMS volt-free common fault relay output for remote system warning signals
• External padlockable mains isolator switch allows the incoming power supply to be physically isolated during servicing and maintenance
• Individual pump circuit breaker protection helps isolate a fault with an individual pump or cable
• Removable gland plate
• Pipe Fill gently fills empty lines and shuts down if pressure cannot be built within 10 minutes
