GE300 Constant Pressure Water Supply Controller (Capable of controlling up to four pumps)
1.1 Controller Features
This product is a newly launched high-performance microcomputer-based water supply controller developed in response to widespread user demand. It is manufactured using high-quality components and materials, incorporating the latest control technologies. When combined with a frequency converter, it forms a microcomputer-based variable frequency speed control constant pressure water supply system suitable for civil, industrial, fire protection, and other applications.
l Utilizes fuzzy control principles, automatically optimizes without needing to adjust controller parameters, offers fast response, high precision, and minimal pipeline impact during pump switching.
l Features automatic timed pump rotation and timed startup/shutdown settings to extend the average service life of pumps.
l The system provides an energy-saving sleep mode.
l When pressure is insufficient and an additional pump is needed, the variable frequency pump automatically reduces speed to minimize switching impact.
l Added boiler water replenishment and pressure relief valve pressure range control options.
l In case of frequency converter failure, it can automatically switch to power frequency operation.
l Functions such as one-in-use one-standby, one-in-use one-supplementary, two-pump, three-pump, four-pump cyclic soft start, etc., to meet various user needs.
l Simplified keyboard menu-style setting and adjustment of operating status.
l Online parameter programming for ease of use.
l Designed with switching power supply, featuring wide voltage range and strong anti-interference capability.
l Components use advanced SMT (Surface Mount Technology) process for high reliability.
l Comprehensive protection and alarm functions, including frequency converter failure, remote pressure gauge open circuit, short circuit fault, undervoltage timeout, low water level alarm indication.
l Complete password functionality.
