HBCPS-646 Variable Frequency Constant Pressure Water Supply Controller

6 working modes, providing typical electrical diagrams to meet different occasions and user needs

The 646 model can control up to 4 water pumps

The pump configuration is flexible, and the instrument can be easily set to achieve common and dedicated water supply modes

◆ Regular rotation control ensures balanced working time of each pump, effectively preventing pump rusting

◆ Sleep function and auxiliary small pump function, energy-saving and consumption reducing, extending equipment service life

Boiler water replenishment control and pressure relief valve pressure range control, with control values set arbitrarily

Overpressure and underpressure in the pipeline network; Inverter malfunction; Water shortage (low water level) alarm in the pool

◆ Multiple input and detection protections to improve water supply system safety and effectively protect equipment

◆ Fault handling function, can still ensure domestic and fire water supply even if the control equipment has faults

PI fuzzy control, fast response, stable control, and minimal impact on the pipeline network during pump switching

Sensor zero and full point correction, adjustable analog output gain, digital filtering

◆ Powered by a switch mode power supply, it can effectively eliminate the interference of the frequency converter on the controller

Both analog and digital signals adopt optoelectronic isolation to comprehensively improve electromagnetic compatibility

◆ Manual and automatic disturbance free switching, can debug and maintain any pump

◆ Suitable for various brands of frequency converters, can be equipped with general pressure transmitters and remote pressure gauges
