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 screwstyle terminal blocks. For added flexibility, computer-style jumpers are provided for rangespecific decimal point assignments. And, to ensure trouble free installation, all models include reverse-polarity protected power supply inputs. Two input configurations are offered: grounded shunt (“low-side”), 5-40V-powered, red LED models for cost-sensitive applications, and 8-36V isolated-supply models that accept high-side or floating shunts. Isolated-supply models are 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. w w .D w + INPUT AMPLIFIER t a CAL S a e h t e U 4 .c m o LED DISPLAY +5V A/D CONVERTER –5V POWER CONVERTER * – ** 1 2 TB1 SIGNAL GROUND 1 1 2 2 TB2 POWER GROUND –IN +IN +V –V (GND) * Not included on all models ** Open on isolated power models EXTERNAL 50 or 100mV SHUNT EXTERNAL DC SUPPLY Figure 1.
