Murata Power Solution’s new DCA5-20PC Series dc ammeters are specifi cally designed to dis-
play 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!
ages that feature a large, 0.37”/9.4mm high, LED display. However, display visibility is not com-
promised 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 assign-
ments. And, to ensure trouble free installation, all models include reverse-polarity protected
power supply inputs.
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.
ammeters the ideal choice for all your 50 and 100mV shunt ammeter-applications.

... Refer to the Functional Specifi cations section for TB1 and TB2 wire gauge information. DCA5-20PC ammeters’ shunt (TB1) and power supply inputs (TB2) are not internally fused. Therefore, the supply wires connected to the meter and the load should be fused according to the maximum current rating (or lower) of the wire gauge used, in accordance with applicable regula- tory codes ...

... Rewiring must be performed with all power sources de-energized. DCA5-20PC ammeters are multiple input-range devices. For example, with a 50mV input, DCA5-20PC-1-DC1 models can be confi gured to display “5.00”, “50.0, or “500” Amps by simply removing or relocating decimal-point-selector jumper J2 (see Figure 6). Decimal points serve as placeholders only ...
