EU-401N PWM - Solar differential controller with graphic display

Product overview

The EU-401N PWM controller is a straightforward and reliable solar controller specifically designed for modern solar thermal systems. This device monitors and controls the temperature difference between the collector and the storage tank.

The integrated graphic display enables intuitive operation and provides a clear overview of the system status at all times. Ideal for anyone looking for simple yet effective control of their system.

How the differential control works

The device's main function is to compare the collector temperature with that of the storage tank. Once the predefined temperature difference is exceeded, the controller switches on 230V at the output. This ensures efficient operation of the connected appliances.

In addition, a potential-free contact is activated, which allows further devices to be integrated into the system. This makes the control system a flexible component in a comprehensive energy management system.

Main functions in detail

The pump is controlled automatically and precisely, ensuring optimal use of solar energy. At the same time, the control system protects against overheating or freezing components, thus extending the lifespan of your system.

An integrated anti-stop function prevents malfunctions and ensures uninterrupted operation. The potential-free contact allows for flexible switching of additional components, enabling individual system expansion.

Advantages and easy assembly

A key advantage of this solar controller is its ease of use. Thanks to its few, but essential functions, the device can be quickly installed and put into operation even by less technically experienced users.

The compact design, combined with the clear graphic display, allows for quick and easy assembly, reducing installation time and costs. This means you'll be ready to go in no time.

Graphic display and ease of use

The user-friendly graphic display provides all relevant information clearly and in real time. This enables easy monitoring of temperatures and system performance without the need for additional devices or external control components.

Thanks to the clearly structured display, you can see important system parameters at a glance and react immediately if necessary. This contributes significantly to the optimal efficiency of your solar system.

Application areas and expansion possibilities

The EU-401N PWM controller is ideally suited for use in residential and commercial solar systems, especially where precise temperature control and reliable protection against extreme weather conditions are required.

The potential-free contact allows you to integrate additional devices into your energy management system. Whether for controlling further consumers or for integration into a more complex system – this control offers you a wide range of applications.

Summary

The Master DE.315/EU-401N PWM solar controller combines ease of use with reliable monitoring of the temperature difference between the collector and storage tank. Thanks to its integrated graphic display and versatile integration options, the device is ideally suited for modern solar thermal systems.

With its robust functionality and integrated safety features, this controller enables efficient operation of your solar power system.Benefit from quick assembly and the sustainable expandability of your system – for an energy-efficient and future-proof solution.
