help with variable psu

[lsufan62]

I am building a variable piwer supply that goes up to 24 volts. My transformer is a 25v 2A on sec side. I assembled a temporary circuit and when I supply power to it my surge protector trips. Any ideas on what I may have done wrong?

welcome to EP

no idea could be anything
show us your circuit and some pic of your construction and we will see if there are any obvious faults
