EU Ecodesign Regulation 2025/2052 Explained New EPS Requirements and the HPA Series Response

The European Union has formally adopted Commission Regulation (EU) 2025/2052, establishing new ecodesign requirements for external power supplies (EPS), wireless chargers (WC), wireless charging pads (WP), portable battery chargers (BC), and USB Type-C cables. This marks the most significant update to the EU's power adapter energy-efficiency policy in over a decade. UL held a dedicated webinar on international eco-regulation trends for external power supplies, offering an in-depth look at the new requirements and how the industry is responding. In this article, we walk through the changes introduced by the amendment, their practical impact on manufacturers, and the current status of Sinpro's HPA desktop power supply series in meeting these requirements.

What Is (EU) 2025/2052?

The European Commission adopted Commission Regulation (EU) 2025/2052 on October 13, 2025, and it was formally published in the Official Journal on November 24 of the same year, replacing the previous (EU) 2019/1782. The new regulation significantly expands the scope of coverage beyond simple external power supplies to the following four product categories:

• EPS (External Power Supplies)
• WC (Wireless Chargers)
• WP (Wireless Charging Pads)
• BC (Battery Chargers)

USB Type-C cables are also covered under the regulation. The new rules entered into force on December 14, 2025, with most mandatory requirements taking full effect on December 14, 2028. However, manufacturers that achieve compliance ahead of schedule may place compliant products on the market starting December 14, 2025.

Five Core Ecodesign Requirements

According to the European Commission, the amendment focuses on five key areas:

Energy Efficiency

The regulation raises minimum efficiency requirements for average active efficiency and efficiency at low load (10% load), and tightens standby power limits (≤0.3W for general EPS, ≤0.5W standby for wireless chargers).

Output Power Performance

Output voltage drop under load is limited, and a corresponding test method is established for "adaptive EPS" units capable of automatically adjusting output voltage.

Interoperability

By default, EPS units must be equipped with at least one USB Type-C or USB-PD port and must carry the "Common Charger" marking. Non-removable, hardwired Type-C cables are prohibited.

Surge Resistibility

The regulation introduces more rigorous surge immunity test requirements, addressing transient disturbances in real-world line conditions rather than steady-state efficiency alone.

Information Requirements

Nameplates and packaging must clearly indicate the maximum rated output power and related information. USB Type-C cables must indicate their supported power rating (e.g., 60W, 240W), and relevant public documentation must be retained and available for review for at least 10 years.

Which Scenarios Are Exempt from Interoperability Requirements?

It's worth noting that the regulation does not require "all" EPS units to comply with USB-C interoperability requirements. The text explicitly lists several exemption scenarios, including the following, which are highly relevant to the power supply industry:

• Products subject to specific industry regulations for safety reasons (e.g., EPS units used in damp environments)
• Products required to withstand specific operating conditions, such as high-level electrostatic discharge (ESD) environments
• Products permanently installed in a fixed location within a building

In other words, an EPS designed for harsh environments and high immunity levels for medical or industrial applications is likely, by its very nature, to fall within the exemption scope for interoperability requirements — which is precisely where Sinpro's HPA series is positioned.

Sinpro's HPA Desktop Power Series: Aligned with the Latest Regulatory Trends

Sinpro's HPA series of desktop external power supplies has already completed the relevant verification and design adjustments needed under the new regulation, well ahead of schedule. The HPA series is designed for medical and industrial applications, with protection and immunity levels — such as high-level ESD immunity, surge resistibility, and optional IPX3 water resistance — that far exceed those of typical consumer-grade EPS units. These technical specifications happen to align with several of the interoperability exemption scenarios listed in the regulation, such as high-level ESD operating conditions and use in damp environments. In other words, exemption eligibility is determined by whether a product's technical characteristics actually meet the scenarios listed in the regulation — not simply by labeling a product "medical-grade" or "industrial-grade." Actual applicability must still be confirmed case by case, based on each product's technical documentation and application scenario. For the HPA series, which already offers this level of protection, there is no need to compromise the product's existing protective design merely to satisfy USB-C interoperability requirements.

Below are several key HPA series specifications that align with the regulation's key points — each one maps directly to the exemption conditions or new requirements discussed above, rather than being a generic marketing claim:

These specifications were not added as a last-minute response to the regulation — they've been part of the HPA series' design DNA from the outset, built to meet the demanding environmental requirements of medical and industrial applications. That's precisely why these existing protection and immunity specifications already align, in multiple technical respects, with the direction of the new regulation, meaning the HPA desktop power supply series requires no additional changes to its existing protective design to meet the new requirements.

Recommendations for Buyers and Design Engineers

As the 2028 mandatory deadline approaches, we recommend that customers planning products for the EU market review, as early as possible, whether their existing external power supplies fall within the scope of the new regulation and whether they meet (or are exempt from) the interoperability requirements. Confirming your suppliers' compliance timelines in advance helps avoid a last-minute scramble as the deadline nears.

If you're seeking a power supply solution for medical, industrial, or other applications requiring high immunity and high protection ratings — one that's already positioned ahead of the new regulation — we invite you to learn more about the full specifications of Sinpro's HPA series.
