What is a High Power Power Supply?

A high power power supply converts AC input into a stable DC output capable of supporting substantial wattage. Unlike low-power adapters, HPPS maintain stable output under continuous high load, making them indispensable for industrial, medical, and research equipment.

Key Features of Our High Power Adapters:

  • Continuous high load support: Power devices reliably without overheating.
  • Stable voltage and current: Ensures consistent performance under varying loads.
  • Energy efficiency: Minimizes heat generation and energy loss.
  • Protection features: Includes overcurrent, overvoltage, and thermal shutdown.
  • Long-term reliability: Designed for 24/7 operation in demanding applications.

Our open-frame series uses optimized PCB layouts, high-quality components, and advanced transformers, ensuring maximum reliability and efficiency.

How High Power Open-Frame Adapters Work

Open-frame high power adapters generally use switch-mode power supply (SMPS) technology, providing high efficiency in a compact design.

1. AC to DC Conversion

AC input passes through a rectifier and filter, producing smooth DC voltage. EMI filters reduce noise and interference.

2. High-Frequency Switching

MOSFET switches convert DC voltage into high-frequency pulses, enabling smaller transformers and improved efficiency.

3. Voltage Transformation and Rectification

The transformer adjusts voltage, and the output is rectified and filtered to maintain stable DC.

4. Feedback Regulation

Feedback circuits monitor output voltage/current and adjust pulse width for consistent performance under varying loads.

5. Thermal Management

Open-frame designs allow natural convection. Critical components include heat sinks or thermal pads to prevent overheating.
