Overview

IPM8303 three-phase portable watt-hour meter test device is a portable desktop watt-hour meter test device with high-tech content developed and produced by Shenzhen Irida Photoelectric Co., Ltd. The product is equipped with three-phase high stability programmed power source and HY5303C-22 three-phase multi-function standard table, which can be operated by keyboard for simple function test and controlled by PC. PC machine has complete inspection items, high measurement accuracy, good long-term stability, high automation, wide output range, small distortion, high stability and other advantages.

This device is suitable for the verification of electronic and electromechanical single-phase active and reactive power meters, as well as multi-functional energy meters.

This device can provide abundant power information: AC voltage, AC current, phase between voltage and current, power factor, active power, reactive power, apparent power, frequency, etc.

The device can have 1-3 epitopes, a built-in error processor, or an external error processor.

This device can be used for product development, product maintenance, production line debugging, etc. In combination with the underlying dynamic link library developed by our company, customers can develop their own automatic meter adjustment software.
