Schneider Electric em6438 Digital Multifunction Meter

Schneider Electric's Conzerv EM6438H is a 96x96 mm, dual-source digital multifunction meter that provides independent energy measurement for two power sources (for example utility and a generator) with two separate energy registers. It features an integrated LED display, an alternate-source input, and RS-485 communications, with accuracy classes of 0.5 or 1.0 depending on variant (EM6438HCL05RS or EM6438HCL10RS). The instrument monitors voltage and current, frequency, true power factor, and active, reactive, and apparent energy (W/VA/VAR and Wh/VAh/VARh), along with run hours and percent unbalance, and supports CT reversal auto-correction in Star configuration. This panel-mount meter is designed for energy accounting and load monitoring across two sources, making it suitable for feeder monitoring in commercial or industrial environments where dual-source energy billing and remote integration via RS-485 are required.
