Products Description
Energy Meter LCD Display Panel High Quality Digital Power Meter
DZ81-MA Three-phase Multi-functional Smart Power Meters are used for measuring, monitoring, and controlling the power distribution system. The digital input helps us to monitor the status of switches, and the digital output gives us the possibility to control them. DZ81-MA Three-phase Multi-functional Smart Power Meters have great extended functions, which connect measuring, analyzing, and controlling together, and make the work become easier.
