The digital panel voltmeter DMS-20PC-DCM series of self-powered, positive-reading, DC voltage monitors are great replacements for older, hard-to-read, analogue panel meters. Simply connect a positive DC voltage across the rear terminals and the meters are fully operational, no additional components or power supplies are required. A rugged, epoxy-encapsulated, polycarbonate case provides excellent protection against moisture, shock and vibration.Digital voltmeters with a large 9.4 mm, red or blue, LED display. Different input voltage ranges from +4.50- +19.99V to +30.0- +264V. Self-powered, only two connections required. Ultra-low power consumption (8 mA typ.). Super reliable, epoxy-encapsulated, construction. Subminiature size with 35x22.4x25.4 mm. Built-in reverse polarity protection assures simple, trouble-free installation.
