APM-5MR (194DR) Digital Multifunction Power Meter

APM-5MR (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, the 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.
