ABL METERL External Load Management Module L

Manage up to 16 EV charging points with dynamic load management via RS485 Modbus RTU. The ABL METERL External Load Management Module L optimizes power distribution for ABL eMH1, eMH3, eMH2, and eMC2 charging stations, preventing overloads and reducing energy costs.

Overview

The METERL is an external load management module designed for dynamic load management in EV charging installations. It measures three-phase current via external current transformers and communicates with charging stations over RS485 (Modbus RTU) to balance the load across up to 16 charging points. This ensures the available power capacity is used efficiently without exceeding the main supply limit.

What stands out

• Supports up to 16 charging points for scalable installations.
• RS485 Modbus RTU interface for reliable communication.
• 3-phase current measurement via external CTs (100A, 250A, 400A, 600A compatible).
• DIN rail mounting (4 modules) for easy integration into distribution boards.
• Wide operating temperature range: -25 °C to +50 °C.
