How to activate the old safety capacitor(II)

4, using a multimeter to measure the restoration of capacity, usually can restore about 60%. If the capacity cannot be repaired, it can be roughly assumed that the safety capacitor has been broken and cannot be activated.

5. When the voltage is adjusted to 350V, the DC voltage across the current safety capacitor is 350Vx1.4=490V, and the activation continues for 48 hours or 72 hours. The number of safety capacitors per start is not limited. After the above-mentioned activation processing of the safety capacitor, it is usually possible to recover to the nominal capacity, and the drain electrode is small.

6. Adjust the voltage to 250V. At this time, the DC voltage at both ends of the safety capacitor is 220Vx1.4=300V or so. Continuously activate for 24 hours. At this time, the capacity can be repaired to 90%.
