Paexplain po ng circuit na toh..

^ and kakayanin po kaya nitong 300v 3 amp and the rest of rectifier ckt ung ac power .

[TinTopHack]

Kung ang input mo ay 240VAC the peak voltage is 240 x 1.414 = 339Vpk.
Worst cast at 260VAC, the peak voltage is 368 Vpk.
You need at least 400VPIV diodes or better use 500PIV diodes.

You circuit appears to be NOT a power on delay circuit. Upon power on, it appears that the relay will turn on according to the delay set by the timer then turn off.

ok n po sir!, na simulate ko na xa half wave pala ang output nya, na try ko n rin po using FWB with d same diodes ok na no transformer used..=).
