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 out-
puts from previously installed high-current CT's, ACA5-20PC's can instantly bring modern
digital precision to older ac ammeters.
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-fi lm resis-
tors for unsurpassed accuracy (±0.15%FS) and stability.
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.
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).
The functionally complete ACA5-20PC ammeters incorporate scaling/interface circuitry
ACA5-20PC meters are either ac (120/220Vac @ 50/60Hz) or dc (+5-40V) powered.
Each meter is housed in a subminiature, 1.38" x 0.88", epoxy-encapsulated package
