Industrial PM-620 Power Meter

Square D PowerLogic PM-620 Power Meter (Class 3020) is a compact panel-mount instrument for real-time monitoring of voltage, current, and frequency in industrial power systems. It can be powered from 90–600 VAC (control power input) with 10 VA burden on 90–264 VAC or 30 VA on 265–600 VAC, and it also accepts a DC input of 100–300 V with a 6 W burden, with isolation rated up to 2000 VAC. Metering inputs include 0–10 A AC on the current input (nominal 5 A) and 35–600 VAC L-L (20–347 VAC L-N) on the voltage input, operating at 45–66 Hz with harmonic response to the 31st harmonic. Nominal voltages typical for common networks are 208/120, 480/277, and 600/347 Vrms, and the unit supports PC-based logging and alarming through POWERLOGIC software for data collection and trending; dimensions are about 5.0 in x 4.0 in x 6.0 in with a weight around 1.2 lb.
