DCA-20PC Series
LED Display, Subminiature DC Ammeters
with Built-In Shunts
Murata Power Solutions’ new DCA-20PC Series are the ?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!
Two shunt-con?gurations are offered: grounded-shunt (“low side”), 5-40V-powered models
for cost-sensitive applications, and 8-36V isolated-supply models for high side or ?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!
DCA-20PC Series ammeters are housed in subminiature, 1.38? x 0.88? (35mm x 22mm),
rugged packages that feature a large, 0.37?/9.4mm high, LED display. A built-in, high-contrast
color ?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.
Built-in shunts, Precision electronics, miniature size, wide power supply inputs, low power
consumption, and no-hassle 3-wire installation make DCA-20PC Series the ideal choice for all
your 200uA to 20A ammeter-applications.
