Murata DMR20 AC or DC Voltage Panel Meter

Murata DMR20 nanoMETER Series includes DMR20-1-ACV Self-Powered 85 to 264Vac LED Display Line Monitor and DMR20-10-DCM 2-Wire Self Powered Auto-Ranging DC Voltage Monitor.

DMR20-1-ACV measures and displays the true-rms voltage of AC power systems. The unit can also measure distorted AC power sources. AC voltages are displayed with 0.1V resolution.

DMR20-10-DCM measures and displays the outputs of the most popular DC power systems. DC voltages are displayed with 0.01V resolution in the LO range (below 51V) or 0.1V resolution in the HI range (above 51V).

DMR20-1-ACV and  DMR20-10-DCM are housed in  rugged, round polycarbonate cases and feature an operating temperature range of -25 to +60ºC. The large 0.30"/7.6mm LED displays can be read from 10 feet away (3 meters). IP67/NEMA 6 protection is provided with hardware supplied with both units.
