This SBL load bank is used to test the on-off capability of the switches intended for self-ballasted lamp loads. The switches used to control the self-ballasted lamp should withstand the electrical and thermal stresses that occur when controlling the LED circuit without excessive damage or other harmful effects. The purpose is to check whether the switch has continuous arc flashing, whether the are welded, and whether the are closed or disconnected for a long time, and whether there is excessive wear and other harmful consequences. This load cabinet fully meets the load requirements of clause 19.3 load B of IEC 60669-1 and clause 19.109 of IEC60669-2-1 for the switches intended for self-ballasted lamp loads.
