Description
English: Low quality components and counterfeits are one of the big factors in the nightmare of the electrical situation in Nigeria. Sold as a good quality German import, closer inspection shows that this ballast is nothing of the kind. For example, examine the printing carefully. Sometimes it's almost impossible to find the real ones.
Русский: Подделаный балласт в Нигерии; производитель не учитывал зависимость индуктивного сопротивления от одной из составляющих - частоты, которая имеет вид 2πfL, то есть индуктивный балласт не может иметь одно и то же сопротивление на двух разных частотах 50 и 60 Герц, т.к. изменяя частоту изменяется и сопротивление балласта.
