DATEL’s DMS-20PC-DCM Series of self-powered, negative-reading, dc voltage monitors are great replacements for older, hard-to-read, analog meters. Simply connect a negative voltage across the rear terminals and the meters are fully operational! Negative-input DCM’s can be easily combined with positive-reading DMS-20PC-DCM’s for monitoring dual-polarity power supplies.
