External current transformer (CT) meter with enhanced metering capability. Now you can monitor Voltage, Amperage, Power, Power Factor, and Reverse Current (very useful for many photovoltaic installations!)
Compact, very easy to install design. Convenient DIN-rail mounting. Electrical wires pass through donut-shaped current transformers (CTs), or CTs clamp around the wires. This allows meters to be mounted up to 6 feet from the CT location. Separate power connection (same voltage as meter, less than 1 watt) needed to power the meter.
Electrical system used by most countries in the world. Most commonly a white neutral and a black “hot” wire, 200V to 252V between the “hot” and the neutral. Very voltage tolerant--the meters will tolerate voltages from 160V to 300V !! Requires ONE CT.
