The compact, rugged, surface mount ACM20 series is designed for use in mains powered applicationsuch as power distribution units, breaker panels and generator sets in industrial, commercial and residential markets. A universal 85 to 264VAC (@47 to 63Hz) operating voltage allows use worldwide, and users can choose from models with a range of either 0-30A (with 0.01A resolution, 7200W max.), or 0-100A (with 0.1A resolution, 9999W max.). Power consumption is less than 0.25W (from a 120VAC supply).
A front panel selector switch provides two modes of operation: a fixed reading of any of the four parameters, or a continuous cycling through of all four measurements. An optional model is available that is also able to display line frequency with 0.1Hz resolution. All ACM20 multi-function Power Meters include built-in current transformers and require no user supplied components.
With a large 9.2mm (0.36in.), four-digit, bright red LED display, ACM20 series’ measurements can be easily read from distances of up to five metres. The one-piece, vibration resistant polycarbonate housing is suitable for installation in vertical 0U and 1U rack spaces, and the surface mount design with overall dimensions of 53.3mm (2.1in.) x 36.3mm (1.43in.) x 12.95mm (0.51in.) occupies minimal panel space. Operating temperature range is 0°C to +60°C.
