MATelec HydroWHIZ FPC-63443-(AA-D) Mild Steel IP56 Inner Door 3PH 1.6-13A DOL Four Pump Controller

For systems requiring four three-phase pumps, the MATelec FPC-63443-(AA-D) HydroWHIZ provides 400Vac control with configurable pump staging and protection. This panel incorporates a pad-lockable mains power isolator switch, a protective inner door, a removable gland plate for cable routing, and DIN-rail terminals. An integrated duty sharing routine alternates the lead pump position automatically based on operating run hours, equalising pump run hours.

Operating on a standard 400Vac supply, the controller feeds the pump contactors and control circuitry. Overcurrent protection utilizes thermal overload protection adjustable from 1.6-13A. The main control module and float inputs operate on a low-voltage 24Vdc control loop, backed by dedicated circuit-breaker protection.

HMI parameters configure the controller for level empty, pressure boost, or temperature control applications. Operational feedback is driven by a 4-20mA transducer and up to eight 24Vdc digital inputs for floats or thermostats. Staggered pump initiation separates starts by a 3-second delay to limit current draw, and stops pumps with a 1-second delay to limit water surge.

HMI features include a colour touchscreen displaying system event counts, pump run logs, date- and time-stamped faults, and trend plots. Visual strobe and audible buzzer indicators provide local fault warnings, with audible buzzer mute function. Standard connections include a volt-free common fault contact for BMS monitoring and Modbus RTU serial RS485 connections for SCADA. Standard software protections include high and low level and pressure protection, and a 7-day pump anti-seize cycle.

Features

• Removable inner door configuration that isolates high-voltage terminal wiring from HMI controls.
• Circuit-breaker protected low-voltage control circuitry operating on a dedicated 24Vdc supply loop.
• Enclosure ground bonding terminal blocks to provide electrical earthing of the panel assembly.
• Dedicated RS485 serial communication port enabling Modbus RTU telemetry to master PLC networks.
• Removable gland plate to facilitate simple site conduit wiring access.
• Integrated real-time clock backed by an onboard coin-cell battery for precise timestamping of system events.
• DIN-rail mounted terminal blocks for neat and organized connection of input sensors and motor cables.
