Equped with filter s from Japan. Two 35V4700UF. 25A high current rectifier bridge. Equped with special inductors for Japanese digital power amplifiers, fully shielded OFC leads.

relay protection circuit. It adopts Japan Panasonic M coupling input MKP 3.3UF.

Refer to the ture, the is installed, for reference only:

Wiring diagram, reference:

● Wiring diagram, you can cli to save as a clear large diagram. ● After installation, please set the jumper to the non-silent mode. The relay will be closed. ● Adjust the adjustable resistance so that the midpoint voltage (DC voltage between OUT and GND) of the two channels is le than 10MV. ● If it is set to bridge mode, the midpoint voltage needs to be re-adjusted.

Performance test chart:

Actual measurement: Carrier working state, before output filter.

Output after the filter:

Work test:

Half-bridge dual-channel mode Input signal 500MV Output 10V *2

BTL full bridge mode Input signal 500MV Output signal 20V *1 (Warning: The dual trace probes of the oscillo share the same ground, so in the test full bridge mode, the oscillo cannot measure the input and output signals at the same time)
