YS106A type three-phase four wire programmable power supplyDetailed product description：

1、 Overview
The YS106A portable three-phase four wire power supply is a new type of fully electronic power supply, which consists of a computer control system, voltage and current power amplification output circuit, and step-up and step-up transformers. It is a dedicated power supply for power supply systems, metrology departments, and industrial and mining enterprises to calibrate AC voltmeters, ammeters, frequency meters, phase meters, power factor meters, single-phase and three-phase power meters, reactive power meters, transmitters, and other power frequency indicators and energy meters.
This product has a unique design, with amplitude, phase, and frequency all set by a numeric keypad, which conforms to the rough, medium, and fine adjustment habits of electrical power supplies. It has fixed phase and frequency functions within the power frequency range, as well as tracking function for mains frequency output. In addition, this product has the ability to select single-phase voltage power output, unbalanced test switch, and active and reactive power mode switch, making it extremely convenient for users to operate and replace old equipment, making it the best choice for users.
