Electronic ballast fault temperature tester
This device complies with N.2.2 of Annex N of IEC 60598 for temperature measurement of mounting surfaces on electronic ballast abnormal conditions or fault ballast conditions. During ballast or transformer failure,
one. Overview:
This device complies with N.2.2 of Annex N of IEC 60598 for temperature measurement of mounting surfaces on electronic ballast abnormal conditions or fault ballast conditions.
During ballast or transformer failure, if the winding is short-circuited, the temperature of the ballast winding does not exceed 350 °C after 15 min. After 15 min, the corresponding mounting surface temperature does not exceed 180 °C.
Similarly, the surface temperature of the installation under abnormal conditions of the ballast should not exceed 130 °C. Measure the temperature of the winding and the mounting surface at ambient temperature and 1.1 times the supply voltage and plot it on the graph, then connect a straight line through these points. The extension of this line should not reach 180 °C at 350 °C winding temperature. This is the point at which the surface temperature is installed (see Figure 9).
Second, the main technical parameters and functions: ECG tester
