The universal ac adapter 24V 2A is built with the latest power supply technologies and the quality components materials to enable high performance. The 24V power adapter features 80-kHz Maximum Switching Frequency, Resonant-Ring Valley-Switching Operation for High operating efficiency, Green-mode Power-Saving Operation for low standby power consumption. Opto-Coupled Feedback Enables 120V to 24V adapter up to 2% Regulation. The 24V DC power adapter offers excellent EMC performance. Effective natural cooling thermal management enhances operating performance and reliability allows the 24V AC adapter to operate at full power at higher ambient temperatures. The 110V AC to 24V DC power supply has versatile protection functions including output voltage over voltage protection(OVP), over load protection(OVP) and short circuit to guarantee a safe operation.

This efficient 220vac to 24vdc power supply employs an isolated-flyback power-supply controller that provides Constant-Voltage (CV) using an optical coupler to improve transient response to large-load steps. The 24V 3A power supply processes information from opto-coupled feedback and an auxiliary flyback winding for high-performance control of output voltage and current. The output voltage is regulated accurately by a high-performance voltage-mode amplifier with an accurate voltage reference. The 24V 3A switching power supply uses power saving techniques to reduce the power consumption, resulting in excellent efficiency performance. The precise output over-voltage protection greatly enhances the system reliability. Effective thermal management reduces thermal stress on power supply reliability, allows the 24V power supply adapter to operate at full power at higher ambient temperatures (see our UL/TUV documents).
