DMR35-DCA Series

Precision DC Shunt Ammeter

www.murata-ps.com

PRODUCT OVERVIEW

The DMR35-DCA series of panel meter performs precision measurements of DC current and is

available in two models offering ranges from 1A to 25A . The 3-1/2 digit numeric display supports

precision measurement, and a fast-responding 21 segment bargraph tracks quickly-changing

measured values.

The internal precision shunt resistors simplify the meter’s use and allow for increased accuracy

compared with solutions relying on external shunt resistors. Rear-accessible DIP switches are

provided for the selection of measurement range and display brightness.

The meter is powered from an external 9-32VDC power supply and typically requires only 37 mA

when operated at 12V. The measurement inputs provide +/-48V of common-mode input range,

simplifying the meter’s use in a wide range of applications.

The DMR35 family features a rugged polycarbonate housing that is mountable in a round hole using

supplied screws, and is designed as a mechanical drop-in replacement for many commonly

available analog movement meters, making it ideal for use in laboratory instrumentation, factory

automation, and other applications requiring precise DC current monitoring
