TF6000 Three Phase KWH Meter Tester

TF6000 portable three phase KWH meter tester is a three phase power source for industrial frequency measurement designed and manufactured by using PWM technologies.

Description

General

TF6000 portable three phase KWH meter tester is a 50 Hz (60Hz) three-phase power source for industrial frequency measurement designed and manufactured by using PWM technologies. It possesses such features as high output power, high voltage, current, and power output stability, high output conversion efficiency, low power consumption, small size, and so on. The three phase KWH meter tester can be widely used in the product research and development by tertiary institutions and technology research and development centers, and also used for on-site maintenance by watt-hour meter manufacturers and their production lines.
