FAQ
Q: How to choose the model number?
A: Please specify the system rated voltage,frequency, harmonic current situation etc. If you do not decide, please advise your detailed problem for us to give you a solution.
Q: What is the standard packaging?
A: 1*manual(or electronic manual)
1* plywood carton
Q: Why should we consider harmonic current content?
A: In the application,there are harmonic current more or less. If the capacitor is not matched with the reactor under the harmonic current,the capacitor will be damaged easily.
Q: How to choose capacitor for new-building demand?
A: you can consider from several sides like the below sample.
