The IN1203000 12V 3A switching power supply provides accurate constant voltage (CV) regulation with High Power, Low Noise and Excellent Reliability. The 12V 3A power supply is based on a flyback converter with offline PWM controller for low standby. The 12V 3A 36W power supply has a compact and lightweight design with very high power density. It features minimum four-point average efficiency in active mode, which is compliant with DoE Level VI, and offers low stand-by consumption. The power supply 12V 3A is protected against destructive electrostatic discharge (ESD) and provides surge immunity against electrical overstress (EOS), and with excellent EMI performance. Efficient heat dissipation design significantly enhances reliability, allows the 12V DC 3A power supply to operate at full power at higher ambient temperatures (see our UL/TUV test reports).
