Murata Power Solutions' new DMR20 Series 'nanoMeters' are the first digital panel meters designed specifically for mounting in industry standard 30.5mm / 1.2 inch round panel cutouts. A rugged, one-piece polycarbonate housing, combined with an EPDM rubber gasket and hex nut, provides excellent resistance to both shock and vibration, as well as moisture ingress protection to IP67/NEMA 6 levels.

The initial product releases are two, self-powered, 2-wire voltmeters. The DMR20-10-DCM is an auto-ranging DC voltmeter with a measurement range of 6 to 75Vdc. The DMR20-1-ACV is a self-powered, true-rms responding, AC voltmeter with a measurement range of 85 to 264Vac (50-60Hz). Both models feature bright, easy-to-read LED displays and ultra-low power consumption. Panel knockout punches and tooling are also available.
