Nowadays, power adapters are used in a wide range of applications, which is very demanding on the performance and safety of power adapters. The functional test of the power adapter is especially important. Today, Shenzhen Intermodal Express will explain to you the input and output characteristics of the power adapter:
First, the power adapter input characteristics
1. Working input voltage and voltage variation range.
2. The frequency and frequency variation range of the input voltage.
3. Rated input current. Refers to the current when the input voltage and output current are at rated conditions.
4. Input sags and momentary power outages. This is a state in which the input voltage drops or momentarily breaks at an instant, and is limited by the rated output voltage and current. The indicators tested were voltage and time.
5. Inrush current.
6, leakage current.
7, efficiency. Because this indicator is related to heat, efficiency should be considered when dissipating heat.
8. In the test, indicate whether the input uses single-phase 2-wire or 3-phase 3-wire.
Second, the power adapter output characteristics
1. Rated output voltage.
2. Rated output current.
3. Voltage regulation accuracy. 1 voltage stability; 2 current regulation; 3 ripple noise, including: maximum ripple voltage, maximum ripple noise voltage.
4. The variation of the output voltage caused by the instantaneous current fluctuation.
