DATEL’s DMS-20LCD-2/3-DCM, self-powered, +90V and +150V voltage monitors set new standards for quality, performance, size and cost. Simply apply dc power to the two rear terminals and the unit is fully operational---no additional components or connections are required! Their large, 0.37”/9.4mm, LCD displays feature built-in “VDC” annunciators and can be easily read from 10 feet. Two models are available: one for +42Vdc nominal operation (+18.0 to +90.0V range, ‘-2-DCM’), the other for +120Vdc nominal operation (+50.0 to +150.0V range, ‘-3-DCM’). Reverse polarity protection and 0.1V resolution are standard on both models.

Like their +12V (‘-0-DCM’) and +24V (‘-1-DCM’) counterparts, DMS-20LCD-2/3-DCM meters utilize a precision analog-to-digital converter and ultra-stable passive components to achieve excellent perfor mance over the wide operating temperature range of 0 to +60°C. A rugged, ABS plastic package provides excellent protection against shock and vibration. DMS-20LCD-DCM’s are the most accurate, LCD-dis play, dc-voltage monitors available at any price.
