After years of development, the inverter (VFD) has begun to transition from a purely industrial product to a civilian field. The use of VFD can be said to have gone to the countryside, (constant pressure water supply) penetrated into thousands of households (inverter air conditioning). But after using it for a while, you will find that the failure rate of VFD is much higher than that of the average household ...

1. Detection of fixed resistors. A. Connect the two pen pens (regardless of positive and negative) with the pins at both ends of the resistor to measure the actual resistance value. In order to improve the measurement accuracy, the range should be selected according to the magnitude of the nominal value of the resistance to be measured. Due to the nonlinear relationship of the ohmic scale, its ...

Instrumentation spreads through all sectors of the national economy and penetrates into all corners of people's lives. For example, in the machinery manufacturing industry, the static and dynamic performance of the product is tested, the processing process is controlled and monitored, and the fault diagnosis in the operation of the equipment is diagnosed. In the electric power, chemical, petroleum industries, ...

This article will focus on the energy sector ...

On June 28, 2016, the three-day Shanghai International Power Components and Renewable Energy Management Exhibition (PCIM Asia) was grandly opened at the Shanghai World Expo Exhibition & Convention Center. Focusing on renewable energy technology, Fuji Electric (China) Co., Ltd. brought new products "Four Beauties" to the exhibition, which were Fuji ...

How to choose a circuit breaker? In fact, there are not a few people who do not know the steps of circuit breaker selection, Fuji Electric's suggestion is that you can roughly choose the model of circuit breaker by following the following 7 steps. When the load is a motor, why must it be protected with a circuit breaker + solenoid switch? That...

Take Fujifilm's FRENIC-VP (F1S)/MEGA (G1S) series inverters as an example: J01 PID control function activation. J01=0: PID does not operate, the inverter does not set the PID function or uses external PID adjustment. J01=1: PID positive action (negative feedback). J01=2: PID Reverse ...

Fuji Electric Corporation (CEO, Director and President: Tsuhiro Kitazawa, Headquarters: Shinagawa-ku, Tokyo) is pleased to announce that the second-generation discrete SiC-SBD* series, a series of power semiconductors, has been released for sale. This product will help drive the ...

Fujifilm ultrasonic flowmeter probe installation method and orientation. There are generally two types of probe mounting: the V method and the Z method, and experience has shown that the V method has a higher measurement accuracy than the Z method without affecting the signal reception. Since the V-method probe is installed for precise positioning, the measurement error mainly comes from the flow regime and ...

The frequency conversion speed regulation function of the inverter (hereinafter referred to as -VFD) is to convert the three-phase power frequency (50Hz) AC power supply (or any power supply) into a three-phase AC power supply with adjustable voltage and frequency. Frequency conversion speed control device can also be sometimes called VVVF, which is mainly used to adjust AC motors (asynchronous or synchronous machines).
