This multi-functional DIN rail electronic energy meter, designed for monitoring energy usage, has multiple advantages, which include excellent reliability and ease of installation. The units are lightweight (the one-phase module is only 18mm wide). This compact meter can withstand currents up to 100-amps and can double that if used in conjunction with an appropriate current transformer. This meter is also available in a three-phase unit. Both the one-phase and three-phase models can support RS485 communication.
