ACA5-20PC Series AC Ammeters are designed to scale and digitally display the output of standard, 5A-output current transformers (50:5A, 500:5A, 1000:5A, etc.). Simply pass the secondary/output wires of the "primary" CT through the ACA5-20PC's on-board CT, apply power to the meter, and you're instantly measuring ac currents over one of 14 ranges from 0-50A (with 100mA resolution) to 0-2000A (with 1A resolution). Because they accept outputs from previously installed high-current CT's, ACA5-20PC's can instantly bring modern digital precision to older ac ammeters.
