The 48V 1.25A AC DC power adapter provides accurate constant voltage (CV) regulation with High Power, Low Noise and Excellent Reliability. As a single output switching power supply, the 48V switching power supply is based on a flyback converter with offline PWM controller for low standby adapters. The 48v 1.25a 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 48 volt dc power supply is protected against destructive electrostatic discharge (ESD) and provides surge immunity against electrical overstress (EOS). Efficient heat dissipation design significantly enhances reliability, allows the 48V 1.25A power adapter to operate at full power at higher ambient temperatures (see our UL/TUV test reports).
