Testing principle:
IEC60669-1:2017 and IEC60669-2-1:2015, only for switches with a rated voltage of 250V.
The load box circuit shall be in accordance with Figure 12b and clause19.3, with rectifier bridge and capacitor.
Device display: Power meter and voltmeter on the device for monitoring.
Calibration method:
Manual test process and calibration method: switch sample is connected to the output terminal of the load box, the oscilloscope is connected to the calibration port, and a 0.2-level standard resistor (resistance value is 0.01 ohm) is connected in series to the switch circuit, and the voltage across the standard resistor is read by an oscilloscope, The formula of dividing the voltage by the resistance to obtain the current (I=U/R=U/0.01=100*U), the measurement waveform diagram (GB16915.1-2014 standard waveform for reference) is as follows:
The measured data is copied to the computer, and the sampled voltage signal is calculated by Excel software. Divide the voltage by the sampling resistance (0.01 ohms) to obtain the measured current value I=U/R=U/0.01=100*U.
The waveform data of 10A-100W is shown in the following table:
In order to ensure consistency and stability, the above data requires more than 5 measurements (including cold and hot), the measured values are within the requirements of the standard.
Automatic test method:
Install the switch sample to be tested to the switch endurance tester, so that the switch terminal is connected with the self-ballasted lamp load box output terminal, and the industrial computer signal line (oscilloscope) is connected to the calibration port. When the switch endurance tester is connected to the command drive manipulator to make the switch closed, the current wave sent by the self-ballasted lamp load box is turned on at a phase angle of 90°, and the industrial computer automatically collects the current peaks Ipeak, I2t, and voltage V, and automatic calculation, comparing standard data, giving a qualified failure judgment.
