MATelec HydroWHIZ FPC-63120-E Mild Steel Three Phase 4 kW Variable Speed Single Pump Controller

When single-pump water transfer, stormwater and sewage applications demand reliable variable-speed control, the HydroWHIZ FPC-63120-E delivers with level, pressure and temperature operating modes. Its 4 kW VSD rating runs from a three-phase 400 Vac supply, with speed adjusted according to system demand.

Control logic allows selection between level, pressure or temperature modes, adjusting speed precisely to match demand. For pressure-control applications, Sleep Assist Speed Minimise gradually reduces pump speed to help the system enter sleep mode sooner, while Sleep Assist Boost temporarily increases pressure before sleep to allow a longer sleep period and reduce pump cycling. These are 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.

Housed in an IP44 mild steel cabinet with integral cooling fan and removable gland plate, the panel includes a colour touchscreen HMI with logged event data and diagnostics, individual pump circuit breakers and a lockable isolator switch. Modbus RTU RS485 enables SCADA communication, and a volt-free common fault relay provides BMS signalling.

Configurable protection includes high and low limits, no-flow and feedback-signal fault 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.
