0.05 Class Three Phase Electric Meter Test Bench

Major Application and Functions:
1) Touch screen operation for control source panel
2) With standard meter together show all necessary parameters in one screen
3) Majorly used in automatic meter calibration setup (connect and disconnect of meter)
4) Calibration setup include two types: fixed load point and load point changing
5) Calibrate the meter through Genus software by applying control protocol offered. 6) With good power stability and high accuracy output
7) Can switch power factor between 1.0 and 0.5L, also phase angle can set & edit by end user. 8) Can switch four different balance & unbalance conditions 9) Independent output for each phase including voltage & current
10) Can ensure constant power output between connect and disconnect of meter. 11) Protection: current open circuit and voltage short circuit, etc 12) With PC communication port RS232

Output & Build time
