Dear Pak Boy
UPS bisa menghandle Harmonic Current yang dihasilkan oleh beban dan HAtmonic Voltage dari SUmberdaya, dengan syarat UPS tersebut menggunakan topology Online (Double convertion)
hal ini bisa teradi karena adanya perubahan bentuk gelombang dari AC-DC-AC sehingga harmonic dari beban di tahan oleh UPS dan sebaliknya rusaknya gelombang tegangan input yang biasa di sebut harmonic voltage, juga akan di hilangkan setelah melewati UPS.
System pada UPS juga masih menghasilkan harmonic pada sumber daya atau pada output tapi cukup kecil yaitu kurang dari 3%
