The IN1204000 12V 4A power supply provides accurate constant voltage (CV) regulation with High Power, Low Noise and Excellent Reliability. The 12v 4 amp power supply is based on a flyback converter with offline PWM controller for low standby adapters, with a compact and lightweight design with very high power density. The 12vdc 4A power supply features minimum four-point average efficiency in active mode, which is compliant with DoE Level VI , and offers low stand-by consumption. Efficient heat dissipation design significantly enhances reliability, allows the power supply 12V 4A to operate at full power at higher ambient temperatures (see our UL/TUV test reports).
