Submersible pump controller, 3-level float switch, overvoltage protection, overcurrent protection, automatic PZM-40 drive control EXT10000317

Intelligent submersible pump control – safety and automation in one

This submersible pump controller is a comprehensive solution for ensuring a reliable water supply. The device combines liquid level measurement, pump control and advanced protection functions, making it an ideal choice for both installers and end users. The controller works with three submersible probes (not included, SZH-01 probes recommended) and a float in the expansion tank, precisely monitoring the water level and starting the pump when needed.

Functionality and protection

The device not only automates the tank filling process, but also protects the pump and installation from damage. It has built-in protection against:

• Overvoltage: protects against the effects of sudden voltage increases in the network.
• Undervoltage: prevents the pump from running at too low a voltage, which could lead to its damage.
• Overcurrent: protects the pump motor from overload.
• Undercurrent: reacts to too little current draw, signaling potential pump problems.
• Auto-reset: automatic reset function after a failure, minimizing system downtime.

Additionally, a built-in 30A contactor ensures reliable switching of the pump on and off. The whole is enclosed in a housing providing durability and resistance to environmental conditions.

User comfort and easy installation

The controller is designed with simplicity of installation and operation in mind. The compact size makes it easy to mount in various locations, and the intuitive configuration allows for quick adaptation of the device to individual needs. Combining control, protection and execution functions in one module saves space and installation costs – a solution appreciated by professionals. Thanks to this, the system works efficiently and effectively for a long time, minimizing the risk of failure and ensuring continuous access to water.
