MATelec HydroWHIZ FPC-63320-H Mild Steel Three Phase 11 kW Variable Speed Three Pump Controller

Water transfer and pressure boosting applications with three pumps are managed by the HydroWHIZ FPC-63320-H, providing variable-speed regulation with level, pressure and temperature operating modes. Its 11 kW VSD rating runs from a three-phase 400 Vac supply, with speed adjusted according to system demand.

With automatic duty rotation and bumpless transfer, the controller balances run hours across the three pumps. Additional pumps are brought into operation as demand increases to maintain the selected setpoint, then removed from service when they are no longer required. In pressure-control modes, Pipe Fill builds line pressure while jacking pump control wakes Pump 1 first, activating additional pumps when demand increases.

Proportional speed control responds to level or temperature signals, with PID control managing pressure using configurable proportional and integral values. The IP44 powder-coated mild steel cabinet includes integral ventilation and a removable gland plate.

System monitoring and configuration are handled through a colour touchscreen HMI, with Modbus RTU RS485 providing connectivity to SCADA systems. The touchscreen provides system and individual pump status, operating modes, logged information, historical faults and trend graphs. A volt-free common fault relay offers remote alarm signalling.

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. Manual operation is available for both the system and individual pumps, with a 10-minute timeout returning the controller to automatic operation.

Features

• Configurable low-pressure and no-flow protection
• 4-20mA analogue input compatible with level, pressure or temperature transducers
• Thermostatically controlled fan provides enclosure ventilation
• Colour touchscreen HMI simplifies on-site commissioning and alarm tracking
• Jacking pump control brings Pump 1 out of sleep first, with the main pumps starting when it can no longer keep up with demand
• Sleep Assist Speed Minimise gradually reduces pump speed to help the system enter sleep sooner
• Circuit breaker protected low-voltage control and input circuitry
