Control unit Wilo-EC-L-1x12A-DOL-MT34-WM-EMS 2543211

Intelligent pump control – reliability and installation protection

The Wilo-EC-L-1x12A-DOL-MT34-WM-EMS control unit is an advanced microcontroller designed for efficient management of a single submersible pump. Thanks to the ability to connect both analog and digital level sensors, this controller provides precise control and optimization of the pump's operation according to current needs. This is an ideal solution for both installers and end-users looking for a reliable and intelligent control system.

Functionality tailored to needs

This device offers a wide range of functions that increase the safety and efficiency of the installation. Two operating modes – “Drainage” and “Filling” – allow for flexible adaptation to various applications, from wastewater drainage to water tank filling. Built-in protections, such as overload protection, motor thermal control, and dry-running protection, minimize the risk of failure and extend the pump's life. Additionally, the periodic pump start-up function prevents it from blocking in case of prolonged inactivity.

• Versatility: Two operating modes (Drainage/Filling) allow adaptation to different application scenarios.
• Safety: Overload and dry-running protection protects the pump from damage.
• Diagnostics: Memory for 10 fault messages facilitates identification and troubleshooting.
• Communication: Remote access via ModBus enables monitoring and control of the device from a building automation system.
• Durability: A housing made of UV-resistant polycarbonate ensures durability even in harsh environmental conditions.

Installation and technical parameters

The device is characterized by a high degree of protection IP54, which guarantees its resistance to the ingress of solids and water, allowing installation in places exposed to moisture. The symbol-based menu and control button make configuration and operation easy even for less experienced users. Thanks to a wide range of supply voltage (220…400 V) and frequency (50/60 Hz), the controller is compatible with most standard electrical installations. The maximum rated power of 4 kW and the rated current of 12 A allow controlling pumps with high power.

The device operates at a supply voltage of 220…400 V and a frequency of 50/60 Hz. The degree of protection IP54 ensures resistance to the ingress of solids and water. The maximum rated power is 4 kW, and the maximum rated current is 12 A.

The device is designed to operate in an ambient temperature from -30°C to +50°C, which makes it suitable for applications both indoors and outdoors. However, remember that the device does not have explosion protection and should be used only outside potentially explosive areas.
