MATelec HydroWHIZ FPC-63220-F Mild Steel Three Phase 5.5 kW Variable Speed Two Pump Controller

Two-pump water transfer, stormwater and sewage applications call for the HydroWHIZ FPC-63220-F, which delivers variable-speed regulation with level, pressure and temperature operating modes. Its 5.5 kW VSD rating runs from a three-phase 400 Vac supply, reducing excessive current draw during pump starting and stopping.

Control logic allows selection between level, pressure or temperature modes, with staggered pump starting reducing excessive current draw and water surge or hammer. Adjustable duty sharing and alternation allow operating responsibility to be rotated between pumps, while bumpless transfer helps maintain smooth operation when the duty pump changes. Sleep Assist Boost and Pipe Fill reduce pump cycling and gently build pipe pressure during startup, with smooth bumpless transitions between active drives.

Housed in an IP44 mild steel cabinet with integral cooling fan and removable gland plate, the panel includes a colour touchscreen HMI with comprehensive diagnostics, individual pump circuit breakers and a padlockable isolator. The touchscreen provides system and individual pump status, logged events and trend graphs. 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 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.

Features

• Eight auxiliary 24Vdc digital inputs for backup float switches and pressure switches
• Modbus RTU RS485 supports SCADA integration
• Dedicated pump circuit breakers ensure physical electrical isolation for each individual drive
• Pipe Fill gently builds pipe pressure during startup
• Jacking pump control brings Pump 1 out of sleep first, with the main pumps starting when it can no longer keep up with demand
• 4-20mA analogue input compatible with level, pressure or temperature transducers
• Volt-free common fault output relay for building automation feedback
