Full-Digital Control Resonant Power Supply Cutting-Edge Super High Efficiency Design







HDPLEX 400W AC-DC adapter is a full-digital control resonant power supply. It uses 2 Oz copper PCB and heavy duty copper lane which ensure high current transfer at super low loss. The end result is an amazing 93%+ efficiency.



Two ST DM2 MOSFETs are used for HDPLEX 400W AC-DC adapter LLC stage. This high power ST MOSFET features a very low recovery charge and time and show up to 40% lower RDS. High dV/dt ruggedness (40 V/ns) allows HDPLEX 400W AC-DC performs reliably even when exposed to large voltage transients such as noise and harmonics on AC power lines.



Two ST MDmesh V power MOSFETs with world's best RDS(on) area ,low gate charge, and low on-resistance, combined with state-of-the-art packaging are used for PFC Stage of HDPLEX 400W AC-DC adpater.

Dual Synchronous Rectification Constant Current&Voltage Output Stage Design





HDPLEX 400W AC-DC adapter use PC55 magent core with full copper coil for LLC transformer,LLC inductor, and PFC inductdor. This separate transformer and resonant inductor design enable balanced thermal Load, prevent overheat, and significantly increase component life.



Two Energy Storage Capacitor with massive 120μF are used. With super Low 0.1W idle power consumption, HDPLEX 400W AC-DC adapter exceeds EuP and DOE Level Vi standard.

Full Protection Suite (OVP,OCP,OPP,SWP,UVP,OTP) 40mm Low Noise DC Fan

HDPLEX 400W AC-DC supports complete set of protection mechanism including OVP,OCP,OPP,SWP,UVP,OTP.

The 40mm super quiet 12V DC fan is dynamically controlled by current detection circuit. HDPLEX 400W AC-DC operates in full passive fanless mode for load less than 250W.
