MATelec HydroWHIZ FPC-63120-I Mild Steel Three Phase 15 kW Variable Speed Single Pump Controller

For single-pump water transfer, stormwater and sewage applications, the HydroWHIZ FPC-63120-I delivers variable-speed regulation with level, pressure and temperature operating modes. Its 15 kW VSD rating runs from a three-phase 400 Vac supply, matching motor speed to demand.

The control module features algorithms that regulate the pump using configurable proportional and PID parameters. Sleep Assist Boost and Pipe Fill reduce pump cycling and gently build pipe pressure during startup, supported by proportional speed control for level or temperature and PID control for pressure with adjustable integral values. Pumps are started and stopped in sequence to reduce excessive current draw and minimise water surge or hammer.

Constructed 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 with comprehensive diagnostics. 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.
