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 out- puts 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 ammeters incorporate scaling/interface circuitry to mate the on-board CT to a precision (3½ digit) A/D converter. The A/D's output directly drives the meters' large (0.37"/9.4mm digit height), easy-to-read, LED displays. All models employ auto-zero circuits, precision bandgap references, and super stable metal-film resis- tors for unsurpassed accuracy (±0.15%FS) and stability. ACA5-20PC meters are either ac (120/220Vac @ 50/60Hz) or dc (+5-40V) powered. AC models can be powered by the same ac supply whose current they are monitoring. All ACA5-20PCs provide 2000Vdc isolation between the measured ac current and their power supply, and all models are UL/CSA recognized. Each meter is housed in a subminiature, 1.38" x 0.88", epoxy-encapsulated package whose behind-the-panel installation depth is 2 inches. Display color options include stan- dard red, high-intensity red, and standard green. Each meter is supplied with a plastic bezel assembly with sealing gaskets (MPS DMS-BZL4-C).
