ACA-20PC-2-DC1-RL-C

20A Input, +5-40Vdc Supply, Red LED Display Subminiature AC Ammeters
ACA-20PC-2-DC1-RL-C
Series Headline Digital, LED-Display AC Ammeters with Built-in Current Transformers
Series Description Murata Power Solutions' ACA-20PC Series are the first 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 meter's two supply terminals, and you're instantly measuring ac currents over one of four ranges (0-2A with 1mA resolution, 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 impose minimal loads (50mA max. and 120mA max., respectively) on their supplies. All models employ auto-zeroing circuits, precision bandgap references, and super stable thin-film resistors for unsurpassed accuracy (+/-0.15%FS) and stability. The functionally complete ACA-20PC ammeters provide all the scaling/interface circuitry to mate the CT's output to a precision (3.5 digit) A/D converter. The A/D's output goes directly to drivers for the meters' large (0.37/9.4mm digit height), easy-to-read, LED displays. AC-powered units have on-board AC/DC converters, and wide-range dc-powered units have on-board linear regulators. AC-powered models can be powered by the same ac supply whose current they are monitoring. The 2A and 20A, 85-264Vac, 50/60Hz (AC1) models feature additional on-board terminal blocks to supply power to the external load. All models provide 2000Vdc isolation between the measured ac current and their power supply, and all are UL/CSA recognized. Each meter is housed in a subminiature, 1.38 x 0.88, epoxy-encapsulated package. Total behind-the-panel installation depth is approximately 2 inches.
