General
PZ series intelligent DC energy meter is designed for applications
such as DC panels, solar power, telecommunications base stations,
and charging ports. This series of instruments can measure voltage,
current, power, forward and reverse power in the DC system. It can
be used for local display and connected with industrial control
equipment, computers, from a measurement and control system. Features
