Smarter energy monitoring with DOLD’s RL9405
24 February 2025
DOLD’S NEW RL9405 Energy Meter, part of the trusted VARIMETER PRO series, provides real-time insights into energy consumption, helping businesses identify inefficiencies and optimise performance.

Designed for energy-intensive applications, from production line machinery to data centres, the 35mm-wide RL9405 is compact and easily installed in both new and existing control panels. It continuously monitors voltages and currents in single and 3-phase mains systems with an earthed neutral conductor, ensuring precise energy tracking to support proactive efficiency improvements.
With a galvanically isolated Modbus TCP/RTU interface, it integrates seamlessly with existing control systems for remote monitoring. Energy data is securely stored even during power outages, ensuring no valuable insights are lost.
Key Features:
- Continuous single & 3-phase voltage and current monitoring
- Comprehensive power and energy measurement
- No separate auxiliary voltage required
- Compatible with standard current transformers
- Simple Modbus configuration.
