MATelec HydroWHIZ FPC-63420-F Mild Steel Three Phase 5.5 kW Variable Speed Four Pump Controller

Speed regulation for water transfer, stormwater and sewage with four pumps is delivered by the HydroWHIZ FPC-63420-F, providing variable-speed regulation with level, pressure and temperature operating modes. Its 5.5 kW VSD rating runs from a three-phase 400 Vac supply, with speed adjusted according to system demand.

The control module executes duty sharing, rotation and staging as demand changes, with bumpless transfer for smooth transitions. Additional pumps are brought into operation as demand increases to maintain the selected setpoint, then removed from service when they are no longer required. Sleep Assist Boost and Pipe Fill reduce pump cycling and gently build pipe pressure during startup, with staggered start-stop delays reducing water surge.

Proportional speed control responds to level or temperature signals, with PID control managing pressure. Housed in an IP44 mild steel cabinet with integral cooling 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 events and diagnostic functions.

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

• Integrated thermostatically controlled fan provides enclosure ventilation
• Pipe Fill gently builds pipe pressure during startup
• Dedicated BMS volt-free common fault relay output for remote system warning signals
• Padlockable mains power 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
• Colour touchscreen HMI provides immediate access to diagnostic pages and parameter configuration
• Sleep Assist Boost temporarily increases pressure before sleep, allowing a longer sleep period and reducing pump cycling
