Coming this year....
The one on the picture is made totally from electronic rubbish.
- 1kW constant load
- speaker protection
- CLC output filter
- short circuit protection
- and few more features :D
- capactive current sense circuit
Bellow short circuit protection that works !!
Another two very old SMPS designs based on IR2153, cold bulb filamets have very low resistance so the overload protection must kick in to protect SMPS.
