Good afternoon,

K1 and K2 are Konnectors (German, abbreviated).
K1 is the Connection to the Mains, whereas K2 is to be connectet to the DUT (device under Test)

... so nothing special at all ...

HI Changpuak,

Thanks for the info and you are right about the amp because i did not read further-it was limited to 10 ma! May i know what is the component that labeled as K1 and K2 as asked by Mr Waleed? Are you referring K1 and K2 as switch?

Hi,
The voltage depends on the parts which you want to test. Usually a 15V type is sufficient. 1A is quite a lot ! We limited the current to about 20mA in order not to destroy the parts.

HI Beh,

It stated as a 15 volt output transformer. Try use a 1 amp transformer.
