DATELs new ACA-20PC Series are the fi rst digital ac ammeters to incorporate on-board current transformers (CT’s), and they are amazingly easy to use. Simply pass the current-carrying load wire through the ACA-20PC’s on-board CT, apply power to the meters two supply terminals, and you’re instantly measuring ac currents over one of four ranges (0-2A with 1mA resolu tion, 0-20A with 10mA resolution, or 0-50A and 0-100A with 100mA resolution). Absolutely no external components, such as expensive low-value shunts or 5A donut CT’s, are required.

Meters are ac powered (120/220Vac @ 50/60Hz) or dc powered (+5-40V) and imposeminimal loads (50mA max. and 120mA max., respectively) on their supplies. All models employ auto-zeroing circuits, precision bandgap references, and super stable thin-fi lm resistors for unsurpassed accuracy (±0.15FS) and stability.
