DMR35-DCxA Series

DMR35 DC Micro and Milli-ammeters

www.murata-ps.com

PRODUCT OVERVIEW

The DMR35-DCxA are a series of five DC microammeters and milliammeters that provide precision

measurements of DC current. 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 rugged polycarbonate housing 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.

These meters are ideal for use in laboratory instrumentation, factory automation, and other

applications requiring precise DC current monitoring.
