DMS-20PC-4-DCM - Self-Powered LED DC Voltage Monitors
The digital panel voltmeter DMS-20PC-DCM series of self-powered, negative-reading, dc voltage monitors are great replacements for older, hard-to-read, analog panel meters. Simply connect a negative dc voltage across the rear terminals and the meters are fully operational, no additional components or power supplies are required.
The DCM’s can be easily combined with positive-reading DMS-20PC-DCM’s (e.g. stock-no.: 810-3365) for monitoring dual-polarity power supplies.
A rugged, epoxy-encapsulated, polycarbonate case provides excellent protection against moisture, shock and vibration.
