Murata Power Solutions’ new DCA-20PC Series are the fi rst digital dc ammeters to include built-in
shunts for measuring dc currents up to 20A. Six ranges provide for precision measurement of
dc currents from 200uA to 20A. These ammeters are 100% self-contained; no calibration or
user-supplied components are required—they even include terminal blocks for your external load
circuit, a feature that enables simple 3-wire operation!
for cost-sensitive applications, and 8-36V isolated-supply models for high side or fl oating shunt
applications. A versatile power supply design accommodates all popular supply voltages from 5 to
75Vdc. Reverse-polarity-protected supply inputs ensure trouble free installation. And, because many
dc ammeters are installed in battery backup applications, power consumption is typically below 1
Watt for 8-36V models, and below 75mW for 5-40V models. To further reduce overall power con-
sumption, the voltage dropped across its built-in series shunt is only 20mV!
rugged packages that feature a large, 0.37˝/9.4mm high, LED display. A built-in, high-contrast
color fi lter ensures that legibility is not compromised: the display can be easily read at distances
up to 15 feet (5 meters). Available LED-display colors include brilliant blue, bright green, and
standard red.
consumption, and no-hassle 3-wire installation make DCA-20PC Series the ideal choice for all
your 200uA to 20A ammeter-applications.

... As a general rule, avoid using excessively long leads between the ammeter and the load. 9. ‘Power ON’ LED: DCA-20PC ammeters include a rear-mounted ‘Power On’ LED. The bright illumination of this LED indicates that the meter’s internal power converter is operational. It does not signify that the ammeter and the external load are connected correctly ...
