The 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 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.Large, easy-to-read, LED display with 9.4mm high digits. LED Colour is the Low-Power Red version. Scales and displays the output of 5A to 2000A, 50mV and 100mV shunts. 50mV shunts also available (e.g stock-no. 810-3267). Factory calibrated to ±0.1% accuracy. Wide power supply inputs with a range from 5 to 40V dc (non-isolated) or 8-36V dc (isolated). Reverse-polarity protection. Completely self-contained, no additional components required. Small package size: 35.1 x 22.4 x 25.4 mm. Screw-style terminal blocks.
