Dummy loads are primarily used for:
Performance evaluation of electronic equipment: Testing the output stability of power supplies, amplifiers, and transformers under varying load conditions.
RF equipment adjustment and testing: Calibrating high-frequency circuit parameters and verifying signal integrity; widely used in testing electronic devices such as power supplies, amplifiers, and transformers, as well as RF-related products.
Inverter maintenance and protection: Connected between the DC capacitor and the IGBT module, allowing for the diagnosis of inverter circuit faults based on changes in light bulb brightness.
LED power supply troubleshooting: Using a 40W or 60W light bulb as a dummy load to quickly pinpoint power supply faults.
