Description

Description Background

The EDF-96A/B Automatic Water Level Controller is an intelligent liquid level control device designed for automatic water supply and drainage control in water tanks, reservoirs, wells, and water towers. It supports automatic water filling, drainage, water shortage protection, and combined upper and lower water level control. Equipped with high-sensitivity stainless steel probes and precision liquid level detection technology, it provides accurate and stable level monitoring across a wide range of 1 cm to 20 m.

The upgraded EDF-96A features an isolated transformer and low-voltage 10V DC probe detection for enhanced safety and reliable operation. Its industrial-grade MCU control system provides stronger anti-interference performance and greater long-term stability than traditional IC circuits. With a high-power 30A relay output and manual/automatic mode switching, the controller is suitable for residential, commercial, industrial, and agricultural water level control applications.

Features
