Lac503p Schematic

: Connected to an optocoupler (like a PC817) to regulate the output voltage.

Typically 2x15W to 2x25W (depending on load impedance). Efficiency: >90%, reducing the need for large heat sinks. lac503p schematic

LG boards from this era are known for "cold" solder joints near the heat-generating components (transformers and large resistors). Safety Warning : Connected to an optocoupler (like a PC817)
