Tips

Always derate the output power by 2.5% per °C above 50°C ambient temperature to ensure long-term reliability. For best EMI performance, keep input and output wiring separated and use twisted pairs for DC connections. When adjusting the output voltage, use a plastic trimmer tool to avoid short circuits on the potentiometer.
