194DR Digital Multifunction Power Meter

194DR Digital Multifunction Power Meter

The 194DR Digital Multifunction Power Meter is the perfect choice for monitoring and controlling power distribution systems, with four direct access keys and a high-definition1.6″ dot matrix LCD screen showing all parameters of a 3P3W or 3P4W LV installation.

35mm Din-rail design makes this multifunction meter possible to install in various monitoring boxes and use in outdoor environments (-20~60°C) . The integrated advanced electrical parameter and logging function can replace the general power recorder to perform real-time online monitoring, with the advantages of improving system reliability making the on-site wiring convenient, and reducing system cost.

With the serial port, BJ-194DR digital multifunction power meter can connect with a PC or other host device; All monitored data can be accessed through a digital RS485 communication port using Modbus Protocol.
