Stk411210e Datasheet | //top\\

The STK411-210E generates significant heat during operation. You use a large aluminum heatsink. Always apply a fresh, thin layer of high-quality thermal paste (silicone grease) between the IC backplate and the heatsink to prevent thermal runaway. 2. Voltage Regulation

Neutral voltage and quiescent current are pre-adjusted during manufacturing, eliminating the need for external potentiometer adjustments. stk411210e datasheet
