The DCA-20PC Series are the first 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.Large, easy-to-read, LED display with 9.4mm high digits. LED Colour is the Low-Power Red version. Built-in shunts for digitally measuring dc currents from 200µA to 20A. Functionally complete, no additional components required. Wide power supply inputs with a range from 5 to 40Vdc (non-isolated) or 8-36Vdc (isolated). 20mV internal shunt minimizes power loss. Includes load connections for easy 3 or 4-wire operation. High resolution, Factory calibrated to ±0.1% accuracy.
