Introducing Murata Power Solutions DCA5-20PC Panel Meters and precision base-mounted current shunts

Murata Power Solutions’ DCA5-20PC Series dc ammeters are specifically designed to display the output of all popular 50mV and 100mV dc-shunts. 25 input ranges provide for precision measurement of dc currents from 1A 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 colours 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 compact 35mm x 22mm rugged packages that feature a large, 9.4mm high, LED display. Display visibility is not compromised in any way and can be easily read at distances up to 5 meters. All input and power supply connections are made using two screw-style terminal blocks. For added flexibility, computer-style jumpers are provided for range-specific 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, green or blue LED models for cost-sensitive applications, and 8-36V isolated-supply models that accept high-side or floating 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 50mV and 100mV shunt ammeter-applications.

Precision current shunts

To complement the DCA5-20PC Series dc ammeters Murata Power Solutions’ also have a range of 50mV and 100mV base-mounted current shunts designed for measuring dc currents from 5A to 1200A. These precision shunts (+/–0.25% accuracy) can be connected directly to MPS’s DCA5-20PC Series of dc ammeters.

Installation is straightforward: simply connect the load circuit to the shunt’s threaded studs and the shunt’s mV Kelvin outputs to the digital ammeter’s input terminals.

Typical Installation example

All models feature a rugged phenolic base that provides 750V isolation to the shunt’s brass terminals, allowing for direct attachment to metal surfaces. A highly stable (+/–15ppm/°C) manganin sensing-element provides a wide –40°C to +60°C operating temperature range.

The 3020 series current shunt range consists of 13 different models for rated currents from 5A to 1200A with 50mV or 100mV outputs depending on model chosen.
