MATelec HydroWHIZ FPC-63120-H Mild Steel Three Phase 11 kW Variable Speed Single Pump Controller

Single-pump control in water transfer and pressure boosting applications with fluctuating load profiles calls for the HydroWHIZ FPC-63120-H, offering variable-speed regulation with level, pressure and temperature operating modes. Its 11 kW VSD rating runs from a three-phase 400 Vac supply, reducing excessive current draw during pump starting and stopping.

The single-pump configuration adjusts speed between minimum and maximum limits to maintain constant system pressure or level. Sleep Assist Boost and Pipe Fill algorithms reduce pump cycling and gently build pipe pressure during startup. Pumps are started and stopped in sequence to reduce excessive current draw and minimise water surge or hammer.

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 colour touchscreen provides system and individual pump status, historical alarms, logged events and analogue feedback trends. A volt-free common fault relay provides BMS signalling, and Modbus RTU RS485 supports SCADA integration.

Protection functions include configurable high and low limits, no-flow detection, feedback signal faults and pump cycle protection. 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.
