1、Drive 28w(T5) energy-saving tube when warm-up(without starter)
2、Power factor(λ)0.99 can reduce consuming electricity and investment of equipment
3、stable curent is not sensitive to the change of voltage with strong adaptation.
4、Total harmonic wave is I-THD<10%
5、Protecting set that can be back to former state is added a wire, which is reliable and valuable.
