Mga masters eto po yung laman ng power saving device na nabibili sa sm at robinson eto po ginagamit ko ngayon. Nakabili kasi ako ng isa tapos binuksan ko at ginaya na lang. Effective siya for 3mons kasi ang observation ko after 3mons nagiging load na siya kaya kung mapapansin nyo 3mons lang yung moneyback guaranty nila.
Cost:
Capacitor 4.75uf; 450vAC = P80
Two Prong Plug 2A; 220vAC =P10
Total: P90.00
Napakalaking savings di ba?
You just need a capacitor of 5-10µF of 220V or 440V according to your area grid voltage is 110V or 220V. For this, I’d recommend buying the oil based capacitors that are used in ceiling fans. They are just 2.5µF, so you need to parallel 2 to 4 capacitors. After that, just connect them into plug and see it works.
