What are the technical characteristics of the switch life test resistance inductance load cabinet

　　This load conforms to the standard: GB10963, GB9816, GB2099, GB15092, resistance and inductance loads in the IEC61058, not only can be used as the overload and life test of appliance switches, relay contactors, etc.What are the technical characteristics of the switch life test resistance inductance load cabinet, let's see how Guangzhou Zhipinhui Electronic Technology is introduced.

　　1. Test voltage: external input, AC single-phase 0~300VAC, 50Hz/60Hz

2. Basic resistive load: current 0.3~30A adjustable, power factor (φ): ≥0.98

Basic inductive load: current 0.3~30A adjustable, power factor (φ): 0.3~1.000 adjustable

3. Load switching mode: panel switch switching (all multi-gear resistors and inductors are connected in series)

The production method of inductor is divided into: iron core inductor

The current waveform meets the requirements of the sine wave, the current spike meets the requirements, and the additional harmonic distortion of the current is within 2%.

The minimum adjustment resistance is 0.1 ohms, and the minimum adjustment inductance is 1mH, which is manually adjusted.

4. The resistance is wound with low temperature coefficient constantan wire, which can work for a long time, and the resistance value is stable and the current is stable
