Selection and matters needing attention of Capacitors in Capacitor Step-down Power supply(II)

Views:0     Author:Site Editor     Publish Time: 2018-03-26      Origin:Site

The following points should be noted when making power supply with capacitor voltage reduction:

1Capacitor voltage is better above 630V, and apply non-polar capacitors, polarity capacitors can not be used.

2Shunt the discharge resistance of the 500K-1M at both ends of the capacitor.

3In the process of assembling and debugging, the 1:1 isolation transformer should be used to connect to the AC220V circuit to prevent electric shock.
