ARCH AC-DC Switching Power Supply AQF120E

120W AC-DC Switching Power Supply with High PFC, Isolation & Load Flexibility

AQF120 Series

Open Frame, U Bracket, or Enclosed — Motor-Ready, Globally Certified with 100,000μF Load Support

The AQF120 120W switching power supply offers exceptional power scalability, delivering up to 180W output with an 18CFM fan, far exceeding the typical 100–130W natural convection and 150W fan-cooled power range of standard open-frame supplies.

The switching power supply supports three power levels (100W / 150W / 180W) to adapt to different cooling conditions, providing excellent design flexibility for applications such as industrial motor drives and control systems.

Unmatched Capacitive Load Handling

With support for capacitive loads up to 100,000μF, AQF120 switching power supply offers dramatically higher load tolerance than competing models. This makes it ideal for high-surge systems like motors, solenoids, and relay controls, where strong voltage stability is crucial.

Outstanding Efficiency, Even in High Temperatures

With up to 93% efficiency at both 24V and 48V outputs, the AQF120 switching power supply remains highly efficient even at elevated temperatures. Thanks to its robust thermal design, the switching power supply can sustain full-load operation at +70°C, delivering reliable performance in harsh industrial environments.

Superior Power Factor Correction (PFC)

Equipped with active PFC, the AQF120 switching power supply achieves a power factor of > 0.99 at 115VAC and > 0.95 at 230VAC—outperforming typical competitor ranges of 0.96–0.98. This ensures reduced harmonic distortion, helping your system meet EN61000-3-2 standards, and making it an excellent fit for industrial-grade power efficiency requirements.

Enhanced Safety with 4000VAC Isolation

The AQF120 switching power supply features 4000VAC I/O isolation, exceeding the 3000VAC commonly found in other brands. This higher insulation strength enhances protection in high-altitude or EMI-sensitive environments, meeting stringent safety demands.

Certified for Global Use

Fully certified to UL / IEC / EN 62368-1, the AQF120 switching power supply ensures safe and compliant use across global markets. The switching power supply also meets strict EMC requirements without needing external filters, streamlining your system design and reducing cost.
