194DR MFM Meter

The 194DR MFM Meter is an extension of the 194 series panel-mounted multifunction meter with a 1.6″ dot matrix LCD screen that displays characters in multiple languages (English is the default).

The 35mm Din-rail mount is ideal for use in outdoor switchgear and protective enclosures. The 194DR Multifunction Power Meter has four direct access keys for easy operation in 3P3W or 3P4W LV installations. All monitored data can be accessed through a digital RS485 communication port using Modbus Protocol.

The 194DR multifunction power meter gathers data for intelligent power distribution or plant automation systems, measuring harmonics and providing multi-tariff records for accounting. It monitors advanced electrical parameters and up to the 51st harmonic for an improved understanding of electrical grid quality.
