Brief Introduction:
The unit measures and displays the characteristics of single phase two wires , three phase three wires, three
phases four wires supplies, including Voltage, frequency, current, power and active and reactive energy,
imported or exported, Max. Demand, THD of voltage and current. Energy is measured in terms of kWh,
kVarh. Max.demand current can be measured over present periods of up to 60minutes In order to measure
energy, the unit requires voltage and current inputs in addition to the supply required to power the product.
The requested current input(s) are obtained via current transformers (CT).
Features:
1.Digit LCD screen with blue backlight.
2.. The button are touch-screen buttons
3.. Characteristics of single phase, three-phase 3-wire or three-phase 4-wire supplies
4..User programmable CT primary, CT Secondary, PT primary & PT Secondary
5.Measuring THD% (total harmonic distortion) of all phases
6. Maximum demand current can be measured over preset periods of up to 60 minutes.
7.a relay pulse output that clocks up measured active or reactive energy.
8.AC/DC auxiliary supply 65~265V AC or 80~380V DC
