www.murata-ps.com DMS-20LCD-0/1 Series Self-Powered, +12V and +24V, LCD Display 2-Wire DC Voltage Monitors FEATURES Murata Power Solutions new DMS-20LCD-0/1-DCM, self-contained, self-powered, dc voltage monitors set new standards for quality, performance, size and cost. Simply apply Self-powered, only two connections required power to the two rear terminals and the unit is operational. No additional components are +6.50-18.00Vdc (0.01V resolution) or required The large, 0.37/9.4mm, LCD display, with +8.0-50.0Vdc (0.1V resolution) input ranges built-in VDC annunciator, can be easily read from 10 feet. Two models are available: one for 12Vdc nominal Ideal for battery-powered systems operation (+6.50-18.00V range, 0.01V resolution), Reverse polarity protected the other for 24Vdc nominal operation (+8.0-50.0V Built-in VDC annunciator range, 0.1V resolution). Reverse polarity protection is standard on both models. Large (0.37/9.4mm) LCD displays The DMS-20LCD-DCM utilizes a precision Subminiature 1.38 x 0.88 x 0.66 packages analog-todigital converter and ultra-stable passive Rugged, ABS package components to achieve excellent performance over the operating temperature range of 0 to +60C. A rugged, Functional Speci cations ABS plastic package provides excellent protection against shock and vibration. DMS-20LCD-DCMs are Input without a doubt the most costeffective, LCD-display, Voltage Range: digital voltmeters available anywhere, at any price.
