A. Add a common mode ferrite choke on output wires to reduce the common emission between 10M ~ 300MHz per lighting EMI regulation.
B. Chassis of LED lamp and chassis of HLG-120H or the FG wire should be connected to the safety ground to reduce the EMI noise, including the conduction
and radiation emission.
C. The additional X-Cap and discharge resistor can reduce the low frequency conduction noise between 9K ~ 1MHz per lighting EMI regulation.
D. L-C filter should be added at the DC input of LED constant current driver to avoid the differential emission and high frequency noise generated by the
CC driver.
