Semi-Potted Design: Moisture-Resistant, Shockproof, and Dustproof

Unlike traditional open-frame power supplies, the ARF130 switching power supply features a semi-potted construction that enhances its resistance to high humidity, vibration, and dust. This not only improves mechanical strength but also extends the product’s operational reliability in demanding environments. The fanless design eliminates moving parts, which means longer lifespan and no dependence on fan durability, making it ideal for maintenance-free systems.

Energy Efficiency with Built-in Power Factor Correction

The ARF130 switching power supply delivers up to 91% efficiency, significantly reducing energy loss and heat generation. With Power Factor Correction (P.F.C.) > 0.9, the switching power supply supports environmentally responsible and energy-efficient design goals. This combination of high efficiency and low power loss results in lower operating costs and greater system longevity.

Certified Safety and Seamless EMC Compliance

Safety and compliance are at the heart of the ARF130 switching power supply's design. Fully certified to UL, IEC, and EN 62368-1 standards, it meets global safety requirements with confidence. The switching power supply provides 4000VAC input-to-output isolation, surpassing many competitors and ensuring robust insulation and user protection. Additionally, it complies with strict EMC standards without the need for external components, simplifying system design and reducing overall costs.

Unique Positioning in the Market: Compact and Cost-Effective

While most competitors only offer semi-potted power supplies starting from 160W or 200W, ARCH delivers a true 130W semi-potted option, giving customers more flexibility and a clear advantage in both size and cost. Compared to similar models, the ARF130 switching power supply not only has a smaller form factor, but also better dielectric isolation, making it a smarter, more efficient choice for sub-200W applications.

Tailored for Versatile Applications

With its compact size, robust construction, high efficiency, and certified safety, the ARF130 switching power supply is a versatile power solution for a wide range of applications—from industrial control systems and automation, to commercial electronics and embedded platforms. When your system demands reliable power without compromise, ARCH delivers.
