LED灯管UL触电危险测试(CCN:OOLV)
触电危险测试:
Electrical - Risk of Shock from relamping - Voltage and current at free end of lamp will be measured when other end is connected to ballast or branch circuit AC power supply (if this latter installation method is also specified). The accessible pins at the end of the lamp shall not present a risk of electric shock hazard. Section 24 of UL 935 describes the test. It should be possible to power the lamp just from the highest rated AC voltage, while adjusting for typical ballast crest factor. For AC power and lighting circuits, the crest factor (ratio of peak to rms) is 1.4. A ballast crest factor of 2.0 is assumed based on typical peaking due to the series capacitor.
我们的LED灯管电源宽电压,直流低压输出,内置 ,这个测试没有通过,不知各位有没有遇到此问题,如何解决的? |
