Designed for Stable and Reliable Power Delivery

Reliable power delivery is essential for today's electronic equipment. Whether supporting office electronics, communication devices, or professional AV systems, unstable power can affect system performance and reduce product lifespan. The AK65WG Series is designed to provide stable continuous output while maintaining consistent performance during normal operating conditions.

Its switching power supply architecture efficiently converts AC input power into regulated DC output, helping electronic equipment operate within stable electrical parameters. A maximum ripple and noise specification of 200mVp-p further supports applications where consistent power quality is important for overall system stability.

The desktop enclosure also allows the power supply to operate independently from the equipment being powered, simplifying replacement and maintenance while reducing thermal influence inside the host device.

Energy Efficiency Supports Modern Product Design

Energy efficiency has become an increasingly important consideration for electronics manufacturers. Besides reducing energy consumption, efficient power conversion helps minimize heat generation, improve system reliability, and support compliance with international energy regulations.

The AK65WG Series achieves a minimum efficiency of 88%, meeting internationally recognized energy efficiency requirements including DoE Level VI, CEC VI, and ErP VI. These standards are widely adopted across global markets and help manufacturers develop products that satisfy both regulatory requirements and customer expectations.

Lower power loss during conversion also means less heat is generated inside the power supply. Reduced operating temperatures help improve long-term reliability while allowing connected electronic equipment to maintain more stable operating conditions.

Comprehensive Protection for Equipment Safety

Electronic devices often operate under varying load conditions throughout their service life. Built-in protection mechanisms help reduce the risk of equipment damage caused by abnormal electrical events.

The AK65WG Series includes several protection functions designed to improve operational safety:

• Over Voltage Protection (OVP) helps protect connected equipment if output voltage exceeds the designed operating range.

• Over Current Protection (OCP) limits excessive output current that could damage internal components.

• Short Circuit Protection (SCP) automatically responds to output short circuits, reducing the possibility of system damage.

• Over Temperature Protection (OTP) helps prevent overheating during abnormal operating conditions.

Together, these protection mechanisms contribute to safer operation and improved product reliability in a variety of application environments.
