Detailed Description

GE300 Constant Pressure Water Supply Controller (controls up to four pumps)

1.1     Controller Features

This product is the latest 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 adjusting controller parameters, features fast response, high precision, and minimal pipeline impact during pump switching.

l        Equipped with automatic timed pump switching 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, and four-pump cyclic soft start meet the needs of different users.

l        Simplified keyboard menu-style setting and adjustment of operating status.

l        Online parameter programming greatly facilitates 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, and low water level alarm indication.

l        Complete password functionality.
