Introduction and selection and classification of electronic

Electronic load is mainly used for power detection, such as UPS power supply, generator set, inverter, voltage regulator, etc.

One, the selection of electronic load:
There are many load brands on the market, how to choose the right electronic load is very important, the selection should pay attention to the following aspects:
1, power size;
2, the power factor requirements;
3. Voltage level;
4. Heat dissipation mode.
Two, electronic load classification:
Electronic load can be divided into three types according to the different types of tested equipment, namely, factory aging detection, product quality detection and identification detection, among which the identification detection has the highest requirements for accuracy, loss and stability.
When the electronic load is used to identify and test the power generation inverter, it must be parasitic compensation, otherwise it cannot simulate L and C AC resonance, cannot simulate an isolated island phenomenon, resulting in the inverter test results are wrong. There are some illegal manufacturers on the market that sell the aging detection load to the inverter enterprise. When used for detection, the resonant frequency will deviate from 0.8Hz for every 3% difference between L and C, which cannot be satisfied by the traditional load. Therefore, an electronic load with parasitic compensation must be provided.
