Safety Certifications That Matter for 360W Power Supplies in Global Markets

When you’re sourcing a 360W desktop power supply for equipment that ships internationally, “it works” is not the finish line. The real requirement is: it works, it’s safe, and you can prove it with the right approvals and documentation—for the exact configuration you will ship (plug type, cable, label, rating, and sometimes even enclosure or connector details).

This article breaks down the safety certifications and compliance marks that matter most for 360W power supplies in global markets, how they connect to the major IEC safety standards, and what buyers should check to avoid shipment delays or re-testing.

1) First, separate “safety” from “EMC” (many buyers mix them)

For external AC/DC power supplies, certifications usually fall into two buckets:

Electrical Safety (risk of shock, fire, overheating)

This is where standards like IEC 62368-1 or IEC 60601-1 matter most. Safety approvals often involve construction requirements, insulation distances, component selection, temperature rise limits, and dielectric strength testing.

EMC / EMI (interference, emissions, immunity)

This is where regulations like FCC (US) or the EMC portion of CE/UKCA come in. EMC ensures your power supply does not cause interference and can tolerate typical electromagnetic disturbances.

A global-ready 360W power supply program needs both—because customs, auditors, and end customers may request evidence for each.

2) The most widely used “passport”: CB Scheme (IEC-based)

If you ship to multiple regions, CB (Certification Body) Scheme is one of the most valuable starting points. CB is built around IEC standards and provides a CB Test Report/Certificate that can help you obtain national certifications faster in many countries.

Why CB matters for 360W power supplies

• It reduces duplicate testing effort when expanding markets

• It anchors your compliance to a recognized IEC standard set

• It helps OEMs manage documentation for multiple regions

Buyer tip
Ask for the CB certificate and the CB test report summary, and confirm the tested model number and configuration match what you will buy.

3) North America: UL / ETL (Safety) + FCC (EMC)

UL (US/Canada safety recognition)

UL is one of the most recognized safety marks in the US market. For power supplies, UL testing often aligns with IEC-based standards (with national differences). In B2B procurement, UL documentation is frequently requested by customers, especially for commercial equipment.

ETL (Intertek) as an alternative safety mark

ETL is widely accepted in the US/Canada and often used as a practical alternative to UL. Many buyers accept ETL as long as it covers the right standard and the listing is valid.

FCC (EMC in the US)

FCC is primarily about electromagnetic interference. For power supplies used with digital devices, FCC compliance is often needed at the system level, but power supplies can also be part of the compliance story—especially if you’re selling a “complete power solution.”

Buyer tip
Don’t assume “UL listed” implies FCC, or vice versa. Ask separately:

• Safety mark (UL or ETL) coverage

• FCC/EMC compliance documents (if required for your product category)

---

4) Europe: CE + GS (and now UKCA for the UK)

CE Marking (EU)

CE is not one single test. It’s a legal marking that indicates conformity with relevant EU directives (commonly Low Voltage Directive and EMC Directive for power supplies). In practice, buyers should ensure the supplier can provide:

• Declaration of Conformity (DoC)

• Test reports supporting safety and EMC requirements

• Proper labeling and technical file support

GS Mark (Germany-focused, voluntary but valuable)

GS (“Geprüfte Sicherheit”) is voluntary but often seen as a trust signal, especially in German and EU retail/commercial channels. For certain buyers and distributors, GS can improve acceptance.

UKCA (United Kingdom)

UKCA is the UK’s conformity marking post-Brexit. If you ship into the UK, UKCA is a common requirement. Many OEMs now maintain both CE and UKCA compliance paths.

Buyer tip
If you ship to both EU and UK, confirm the labeling and DoC/UKCA documentation are prepared correctly for each market. Mixing labels or using incomplete documents can cause delays.

---

5) Australia/New Zealand: RCM

RCM is commonly required for Australia and New Zealand, covering both safety and EMC requirements depending on product category. For external power supplies, it’s a frequent checkbox for importers and distributors.

Buyer tip
Confirm whether the supplier supports the correct RCM compliance level for your product type and can provide supporting test evidence.

---

6) Japan: PSE

Japan’s PSE requirements are strict and commonly requested for power supplies sold in Japan. If your customers target Japan, PSE can become non-negotiable.

Buyer tip
Make sure the exact model, rating, and label format are aligned with PSE requirements. Japan-related compliance often cares about labeling details and document completeness.

---

7) Korea: KC

KC is widely needed for Korea and typically involves safety and EMC elements depending on the product. Korean importers often request KC mark support as part of vendor qualification.

Buyer tip
Ask if the manufacturer can support KC with the correct scope (safety/EMC as required) and whether the model and configuration are stable for repeat orders.

---

8) India: BIS

BIS compliance is increasingly important for power supplies sold into India. It may require specific registration pathways and strict document alignment.

Buyer tip
India is one of the markets where “close enough” documentation creates real problems. Confirm that the supplier has experience with BIS processes and can keep configuration changes controlled.

---

9) Singapore: PSB

For Singapore, PSB is often referenced in compliance discussions, especially for certain regulated product categories. If your customers ship into Singapore or supply Singapore-based projects, this can be a practical requirement.

---

10) China domestic: CCC

If you sell into China domestically or supply equipment that needs China’s domestic compliance pathway, CCC can be a key requirement.

Buyer tip
CCC scope depends on product category. If CCC is required, ensure the supplier understands whether your power supply model falls within the regulated list and can provide proper documentation.

---

11) Which IEC safety standard applies depends on your application

This is the part many buyers skip, then regret later. A power supply may be safe, but it must be evaluated against the right standard family.

Common IEC standards for power supplies include:

• IEC 62368-1: Audio/Video, IT equipment, communication technology (very common for modern external power supplies)

• IEC 60335: Household and similar appliances (relevant when your supply is used with home appliance products)

• IEC 61558: Safety of transformers and power supply units (often relevant depending on design category)

• IEC 60601-1: Medical electrical equipment (medical-grade power supplies need this pathway)

• IEC 61347: Lamp controlgear / LED driver related safety (relevant if your supply is positioned for lighting/LED systems)

Buyer tip
If your end product is medical, don’t “assume” a general ITE power supply is acceptable. Medical compliance often requires stricter leakage current limits and documentation discipline.

12) The most common compliance failure: configuration mismatch

Even reputable manufacturers run into buyer issues when the shipped configuration differs from the tested configuration. At 360W, small changes can matter:

• Plug type or detachable cord set changes

• Output cable length/gauge changes

• Connector changes

• Label rating or model name changes

• Internal component substitutions that affect safety-critical performance

What to ask the supplier

• Are plug/cable variants covered by the same certificate?

• Do you have a controlled BOM and change notification process?

• Can you provide the exact label artwork and DoC for our market?

• Do you maintain traceability by batch/serial?

This is how you protect your project from “surprise re-test” costs and shipment delays.

13) A practical reference for global-ready sourcing: GJ350WD Series

If you’re evaluating a 360W desktop power supply for OEM projects across multiple regions, use a product like the GJ350WD series as a reference point and confirm which certifications and standards match your target markets and application category. You can review it here: 360W Power Supply-GJ350WD Series Desktop Series Power Supply.

For faster evaluation, provide your supplier with:

• Target markets (US/EU/UK/AU/JP/KR/IN/SG/CN, etc.)

• End product category (ITE, appliance, medical, lighting)

• Required marks (CB, UL/ETL, CE, UKCA, RCM, PSE, KC, BIS, PSB, CCC)

• Expected order plan and configuration details (plug, cable, connector, label)

That turns “do you have certificates?” into a clear compliance plan that supports long-term supply.
