Murata Power Solutions’ new DCA5-20PC Series dc ammeters are specifi cally designed to display the output of all popular 50mV and 100mV dc-shunts. 25 input ranges provide for precision

measurement of dc currents from 1.000A to 2000A. With the exception of an external shunt,

the unit is 100 self-contained – no calibration or user-supplied components are required.

Available LED-display colors include brilliant blue, bright green, and standard red. Three power

supply options accommodate all popular dc-supply voltages from 5V to 75Vdc, making these

ammeters perfect for automotive, industrial, telecom, and marine applications!

DCA5-20PC Series ammeters are housed in 1.38” x 0.88” (35mm x 22mm) rugged packages that feature a large, 0.37”/9.4mm high, LED display. However, display visibility is not compromised in any way: the display can be easily read at distances up to 15 feet (5 meters). All

input and power supply connections are made by way of two screw-style terminal blocks. For

added fl exibility, computer-style jumpers are provided for range-specifi c decimal point assignments. And, to ensure trouble free installation, all models include reverse-polarity protected

power supply inputs.

Two input confi gurations are offered: grounded shunt (“low-side”), 5-40V-powered, red,

green or blue LED models for cost-sensitive applications, and 8-36V isolated-supply models

that accept high-side or fl oating shunts. Isolated-supply models are also available in a choice

of red, green, or blue LEDs. Since many dc ammeters are used in battery backup applications,

power consumption for 8-36V models is typically 1 Watt, and 75mW for 5-40V models.

Miniature size, wide supply inputs, and no-hassles installation make DCA5-20PC Series

ammeters the ideal choice for all your 50 and 100mV shunt ammeter-applications.
