Frequently Asked Questions
What certifications does this power adapter have? Does it have UL/CE/FCC certificates?
This unit is certified with UL (US safety certification), CE (EU safety certification), FCC (US electromagnetic compatibility). Some models optionally include PSE (Japan), KC (Korea), SAA (Australia), CCC (China compulsory certification), etc. The UL certification number is traceable, and CE declaration documents are complete. For bulk purchases, a copy of the UL certification, CE declaration, and FCC test report can be provided simultaneously, ensuring smooth export customs clearance and customer factory audits. For overseas customers with special certification requirements, separate certification applications can be arranged.
What is Energy Efficiency Level VI? What are the requirements for power adapters?
Level VI is the sixth-generation energy efficiency standard established by the US DoE (Department of Energy), mandatorily implemented since February 2016. Core requirements: ① No-load power consumption ≤ 0.1W (Level V is 0.3W);
② Average conversion efficiency ≥ 87% (for models ≥150W) or ≥ 87.3% (<150WLevel VLevel VI15~20%Level VIErP
How to choose the right DC connector? What are the differences between different DC connector specifications?
Choosing a DC connector requires confirming three parameters: ① Outer Diameter (OD) × Inner Diameter (ID), common specifications include 5.5×2.5mm, 5.5×2.1mm, 3.5×1.35mm, etc.;
② Polarity — most devices use center positive (inner positive, outer negative), a few special devices use center negative (inner negative, outer positive), please check the original adapter label of the device to confirm;
③ Rated current — the DC connector's rated current must be ≥ the adapter's output current. This unit comes standard with a 5.5×2.5mm center positive DC connector, which can be replaced with other specifications as needed, simple to change without tools.
Is this power adapter constant voltage output or adjustable output?
Determined by the model specification: Fixed voltage versions output the nominal voltage (e.g., 12V/24V), suitable for most standard devices; adjustable voltage versions allow output voltage adjustment within a specified range via a potentiometer knob (e.g., 9~48V adjustable), suitable for R&D testing and multi-device compatibility scenarios. Notes for using adjustable versions: ① Disconnect the load before adjusting;
② Confirm the voltage matches the device after adjustment before powering on;
③ For long-term use, it is recommended to fix the knob position to prevent accidental changes. For bulk applications, fixed voltage versions are recommended (more stable, lower cost).
What is the difference between medical-grade power adapters and ordinary power adapters?
Medical-grade power adapters must meet the IEC EN60601 standard. Core differences: ① Leakage current — ordinary adapters ≤ 0.5mA, medical-grade BF type ≤ 0.1mA (patient contact part);
② Isolation voltage — ordinary adapters 2×MOPP (4000VAC), medical BF type must meet BF type application part requirements;
③ Insulation class — must meet double insulation or reinforced insulation requirements;
④ Creepage distance and electrical clearance — ≥ 8mm (BF type application). Medical devices (monitors, ventilators, etc.) must use medical-grade adapters; ordinary adapters are prohibited for medical applications.
Does this power adapter have protection functions? What happens during overvoltage or overcurrent?
This unit has multiple built-in safety protections: ① Overvoltage Protection (OVP) — automatically shuts down when output voltage exceeds the set value (usually 110~120%) to prevent damage to downstream devices;
② Overcurrent Protection (OCP) — automatically limits current or shuts down when output current exceeds the rated value;
③ Short Circuit Protection (SCP) — immediately shuts down when the output is short-circuited, automatically recovers after the short circuit is cleared;
④ Overtemperature Protection (OTP) — reduces power or shuts down when internal temperature exceeds 85°C, automatically recovers after cooling. After fault clearance, the adapter automatically restores power supply without manual restart.
What is the warranty period and after-sales service for this power adapter?
This unit has a standard warranty period of 2 years. Non-human damage within the warranty period is repaired or replaced free of charge. Domestic customers enjoy a 48-hour response time and repair completion within 7 working days; overseas customers can arrange DHL/FedEx repair by mail or local agent warranty. Products beyond the warranty period offer paid repair services (cost approximately 30~50% of new product price). Lifetime technical support is provided (selection consultation, application solution design). Annual framework agreement customers enjoy priority production scheduling, free samples, factory inspection support, and other value-added services. Bulk purchases (500 units or more) can apply for an extended warranty of up to 3 years.
What is the maximum output power of this power adapter? What load can it handle?
The maximum output power of this unit is determined by the model specification. When selecting adapter power, it is recommended to calculate the minimum adapter rated power as "device power ÷ 0.8" (i.e., P_adapter ≥ P_device ÷ 0.8). For example, if the device requires 200W, it is recommended to choose an adapter of 250W or higher. Choosing too small will cause the adapter to overheat and shorten its lifespan, while choosing too large increases procurement cost and size.
Can I customize the logo and packaging after purchasing this power adapter?
Yes. Winna Technology offers OEM customization services: ① Housing logo—silk screen/pad printing/laser engraving (MOQ 500 units);
② Custom packaging—color box/white box/neutral packaging (brand, model, parameters all customizable);
③ Product label—includes customer model, certification marks, SN code, etc.;
④ Factory parameters—output voltage can be preset per customer specifications;
⑤ Multi-language manual customization. OEM custom MOQ is typically 500 units, with delivery 15–25 working days after sample confirmation. Standard products (non-custom) have an MOQ of 100 units, and in-stock inventory can be shipped within 48 hours.
What type of plug does this power adapter come with? Can it be changed?
This unit is shipped with a plug type selected based on the target market (US Type A/B, EU Type C/F, UK Type G, AU Type I, etc.). Multiple models support a replaceable plug design (modular plug), allowing one adapter to be used with multiple country plug modules for global use. To change the plug, simply pull off the existing plug module and snap on a new one—no tools required. If your device needs to be sold in multiple countries, we recommend choosing the replaceable plug version (for added flexibility) or specifying the plug type for your target market (for lower cost).
What is the lifespan of this power adapter? Will long-term plugging damage it?
The design lifespan of this unit is ≥50,000 hours (MTTF, Mean Time to Failure), equivalent to approximately 5.7 years of continuous operation under rated load and normal temperature. Long-term plugging will not damage the adapter; this unit complies with Level VI energy efficiency standards, with no-load power consumption.<0.1W
What is the output ripple of this power adapter? Will it affect precision equipment?
The output ripple (Ripple & Noise) of this unit is ≤1% of rated voltage (typical), e.g., for a 12V model, ripple ≤120mVp-p. For applications sensitive to ripple, such as audio equipment, precision measuring instruments, or medical devices, we recommend selecting a model with lower ripple (≤50mVp-p) or adding an LC filter circuit. Excessive ripple may cause issues like audio background noise, measurement errors, or abnormal device restarts. Please contact Winna technical support with your application details for the most suitable model recommendation.
