The compact DMR20-10-DCM ‘nanoMeter’ auto-ranging DC voltmeter is designed for mounting in an industry-standard 30 and 30,5 mm round panel cutout. Occupying minimal space, the round voltmeter has a 7,6 mm four-digit LED display and is self-powered.
Connection to the +6 to +75 V d.c. supply to be monitored is all that is required for full operation. Since no additional components or separate power supply are required for the DMR20, it is straightforward to add into virtually any equipment using a DC supply or batteries. A user configurable jumper provides voltage display to a fixed 0,1 V resolution (input +6 to +75 V) or to a 0,01 V resolution when the input is below +51 V.
The voltmeter is packaged in a rugged plastic housing that has been designed to provide protection to IP67/NEMA 6 specifications for water ingress. It is supplied with an EPDM rubber gasket and plastic hex nut ready to mount in the industry standard panel cutout. Tooling is readily available to drill and punch the cutout, and can also be ordered with the DMR20.
