The UNDE 120W P Series is a desktop-type peak-load compatible AC/DC adapter (120W) designed for equipment that requires high inrush current, such as amplifiers, printers, smart speakers (voice assistants), motors, and pumps. It complies with safety standards 62368-1, 60950-1, and 60065-1 as well as PSE Appendix Table 8. Available in four models ranging from 12V to 24V, with two types: UNDEC3120 and UNDET3120.
With a 5-second peak load function enabling up to 190% of rated output peak current, it is ideal for motors and pumps with high inrush current at startup, as well as amplifiersProducts that require instantaneous high power during music playback. Equipped with a Power Factor Correction (PFC) circuit for superior power quality. Complies with Energy Efficiency Level VI (ErP/DoE), EU Commission Regulation (EU) 2019/1782, and DOE 10 CFR Part 429 and 430. All models feature low standby power consumption of 0.21W.
| UNIFIVE is chosen because: As a power supply manufacturer with over 35 years of development experience, we provide comprehensive support from specification planning with mass production in mind, certification acquisition, production launch, to post-mass production follow-up. Based on standard products, we offer flexible supply from small-lot prototyping and evaluation to small and medium-scale production, as well as large-volume production. We also support semi-custom solutions and assist with power supply selection from the specification planning stage for mass production adoption. |
Key Features
1) 5-Second Peak Load Function - Up to 190% of Rated Output
The key feature of this series is the 5-second peak load function. It delivers up to 190% of the rated output peak current for 5 seconds. The 12V 10.0A model supports up to 19.0A peak, the 15V 8.0A model up to 15.0A peak, the 19V 6.3A model up to 11.6A peak, and the 24V 5.0A model up to 9.0A peak. It ensures stable power supply to equipment such as motors, pumps, and amplifiers that generate high inrush current at startup.
2) For Amplifiers, Printers, Smart Speakers, Motors, and Pumps
Optimized for power supply applications in a wide range of equipment requiring instantaneous high power, including amplifierProducts, printers, voice assistants (smart speakers), motors, and pumps. In addition to ICT equipment safety standards 62368-1 and 60950-1, it also complies with 60065-1 for household appliances, supporting adoption in ICT equipment, audio-visual equipment, and home appliances. For detailed certification status of each model, please contact our sales department.
3) Built-in Power Factor Correction (PFC) Circuit
Equipped with a Power Factor Correction (PFC) circuit, achieving a power factor of 0.9 or higher at both AC100V and AC230V input. It reduces the impact of harmonic currents on power lines and ensures stable power quality. Contributes to improved overall facility power efficiency in 120W-class Products handling high power.
4) EMC Compliance for ICT and Household Equipment (CISPR 32, EN55035, BS EN55032, BS EN55035)
Compliant with EMC standards for ICT equipment including CE CISPR 32 EN55032, BS EN 55032 (emission), EN 55035, and BS EN 55035 (immunity). Also supports FCC Part 15 Class B and VCCI Class B. Compliance with BS EN standards supports certification for Products intended for the UK market.
5) High Efficiency 88% - Available in 2 Types
All four models achieve 88.00% efficiency. Compliant with Energy Efficiency Level VI (ErP/DoE), EU Commission Regulation (EU) 2019/1782, and DOE 10 CFR Part 429 and 430. Available in two types: UNDEC3120 (C plug) and UNDET3120 (T plug), both with dimensions of 174.70 x 72.30 x 35.10mm. Over Temperature Protection (OTP) is optional.
