HBCPS-646/1286W Variable frequency constant pressure water supply controllerDetailed product description：

1、 Function Overview of HBCPS-646/1286W 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 1286W model can control up to 8 water pumps, and can automatically send fault alarms to mobile phones through an external modem. The pump configuration is flexible, and the instrument can be easily set to achieve common and dedicated water supply modes Timed rotation control ensures balanced working time of each pump, effectively preventing pump rust and sleep function, and auxiliary small pump function, saving energy and reducing consumption, and extending equipment service life

Boiler water replenishment control and pressure relief valve pressure interval control, with control values set arbitrarily, and overpressure and underpressure in the pipeline network; Inverter malfunction; Water shortage (low water level) alarm in the pool
Multiple input and detection protections improve the safety of the water supply system, effectively protect equipment, provide fault handling functions, and ensure the supply of water for daily life and firefighting even in the event of equipment failures
PI fuzzy control, fast response, stable control, minimal impact on the pipeline network during pump switching, zero and full point correction of sensors, adjustable analog output gain, digital filtering, using switch power supply, can effectively eliminate the interference of frequency converter on the controller. All analog and digital signals are optically isolated, comprehensively improving electromagnetic compatibility. Manual and automatic disturbance free switching can be used to debug and maintain any pump

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