ACA5-20PC-9-AC1-RL-C

The ACA5-20PC-9-AC1-RL-C is a red standard LED-display AC Ammeter designed to scale and digitally display the output of standard, 5A-output current transformers. Simply pass the secondary/output wires of the primary CT through the ACA5-20PC's on-board CT, apply power to the meter and instantly measuring AC currents over one of 14 ranges from 0 to 500A. Because it accept outputs from previously installed high-current CT's, ACA5-20PC's can instantly bring modern digital precision to older AC ammeters. The functionally complete ACA5-20PC ammeter incorporates scaling/interface circuitry to mate the on-board CT to a precision (3-1/2 digit) A/D converter. The A/D's output directly drives the meters' large (0.37 inch/9.4mm digit height), easy-to-read, LED displays. All model employ auto-zero circuits, precision bandgap references and super stable metal-film resistor for unsurpassed accuracy (±0.15%FS) and stability.

• Easy to read
• AC models can be self-powered
• Digital replacements for analog ammeter
