To evaluate the performance of a quick charger, we need to test its compatibility of quick charger protocols, and then the loading performance. ITECH’s new arrival product IT-E255A, quick charger controller, can perfectly do the job. The box supports QC2.0/QC3.0/PE/PE2.0/USB PD, and more importantly, it can communicate with electronic load (such as ITECH IT8500+).We can set loading mode and value on it.
For most of the electronic loads, their common problemsarethey take up too much space,consume a lot of energy, and generate heat and noise. However, ITECH IT8300 Energy-regenerative electronic load solves these issues.This article gives the answers from ITECH manufacturersto the typical questions engineers concerned about, especially related to the advantages of the IT8300.
As the renewable resources has become more and more popular, the wind farm construction has been increasing in recent years. However, the electricity generated by wind power is usually unstable. Here, a reactive power compensation device plays an important role on regulating voltage, power factor, harmonics and stabilizing the power system.
An AC motor is an electric motor driven by an alternating current (AC).The impact of the motor's starting current may cause the output voltage of the power supply to drop or trigger the overcurrent protection, resulting in failure to start. After the AC motor is started, as the motor speed increases, the stator current will quickly stabilize and then work within the rated current range. If we use a power supply with very high output current just to avoid the impact of start current, it will increase the equipment cost at the same time.An effective method to solve the problem of the starting current is the soft start of the motor.
The equipment capacity of wind farms has expanded dramatically as the scale of wind farm construction in China has increased, and the impact on the power grid has become increasingly serious. SVG dynamic reactive power compensation device plays an important role in meeting reactive power, harmonic control, improving power factor and power quality, reducing loss, adjusting voltage and so on.
