Ac load bank is an important part of power system, which is mainly used to consume electric energy and maintain the stable operation of power system. It is widely used in industry, commerce and homes to provide power support for various electrical equipment.

Alternator AC load bank is a device used to simulate a real load and provide it with energy. It precisely controls the power and current of the load through electronic control to ensure stable operation of the generator under various load conditions. This paper will introduce in detail the use of alternating-current  load bank.

One of the main advantages of generator load detection is the ability to perform preventive maintenance. By continuously monitoring the load on the generator, technicians can detect any potential problems or failures in time, so that the necessary precautions can be taken to prevent a major failure of the generator.

Generator false load detection is an important method for testing generator performance and reliability. By using dummy loads, the operation of the generator under actual load conditions can be simulated, resulting in a more accurate assessment of the performance and reliability of the generator. This paper will introduce the detection method of generator false load detection, including preparation stage, test stage and result analysis stage.

In the work, it is necessary to consider the radiator selection of AC power amplifier. The power amplifier used has a very large capacity, with a current of 40A and a power of 400W.

Programmable DC power supply has the advantages of low voltage and large current, not only in the range of 0-10V, the maximum current up to 50kA, instantaneous current rise time is less than 5ms, less than 2ms, less than 1ms optional, very suitable for a variety of low voltage electrical testing requirements.

With the rapid development of power electronics, product development has higher requirements for programmable AC power supply, that is, programmable AC power supply with high precision, programmable, wide range and other advantages.

With the continuous development of electric vehicles, the demand for charging piles is increasing. In the past, the actual environment test method was usually used for the charging pile test. Now some manufacturers are also choosing electronic load test charging posts. However, during testing, engineers may encounter the following situations.

From October 26 to 28, 2023, the 8th World Oil and Gas Equipment Expo was held in Hainan International Convention and Exhibition Center.

Do not worry when the DC and AC power supplies are faulty. Some small problems can be solved simply by eliminating them. Previously, Xiaobian shared the fault caused by "insulation amplifier" and swing, today specifically said the ground line and ordinary line caused by the problem.
