The UHDE 45W P Series is a desktop-type AC/DC adapter (45W class) for home appliances with peak power capability. It complies with home appliance safety standards 60335-1 and 61558-1, as well as PSE Appendix 8. It can supply up to 200% of the rated current as peak output for 11 seconds, making it ideal for home appliances requiring inrush current at startup or sustained high loads, such as amplifiers, printers, voice assistants, motors, and pumps. Four models are available from 12.0V to 24.0V, with support for an LED display (optional).
Featuring a desktop housing with AC inlet input, it offers a high-efficiency design compliant with Energy Efficiency Level VI (ErP/DoE). It also complies with EU Commission Regulation (EU) 2019/1782 and DOE 10 CFR Parts 429 and 430. All models achieve low standby power consumption of 0.1W at no load. In addition to short-circuit, overvoltage, and overcurrent protection, over-temperature protection (OTP) is provided as standard.
| UNIFIVE Advantages: As a power supply manufacturer with over 35 years of development experience, we provide comprehensive support from specification review for mass production adoption to certification acquisition, mass production launch, and post-production follow-up. Based on standard products, we offer flexible supply options from small-lot prototyping and evaluation to small and medium-scale production, as well as large-volume production. Semi-custom solutions are also available, and we support power supply selection from the specification planning stage through mass production adoption. |
Key Features
1) Peak Power Support - Up to 200% of Rated Output for 11 Seconds
Capable of delivering up to 200% (2x) of the rated output current for 11 seconds. It supports extended peak output demands exceeding the rated capacity, such as inrush current during motor or pump startup, sustained high-volume output from amplifiers, and continuous printhead driving in printers. For example, the 12.0V 3.8A rated model can output 6.8A for 11 seconds during peak operation.
2) Compliant with Home Appliance Standards (60335-1, 61558-1)
Complies with home appliance safety standards 60335-1 (Safety of household electrical appliances) and 61558-1 (General requirements for transformers and power supplies), as well as PSE Appendix 8. Designed for power supply applications in appliances requiring compliance with the 60335 standard, such as electric cooking appliances, fans, air conditioners, and air purifiers. Please contact our sales department for detailed certification status of each model.
3) Ideal for Amplifiers, Printers, Voice Assistants, Motors, and Pumps
In addition to general home appliances, it is designed as a power supply for amplifier products, printers, voice assistants, motors, and pumps that require instantaneous or sustained high current. The 11-second peak power capability enables support for longer high-load cycles beyond what sub-second peak support can handle.
4) Standard Over-Temperature Protection and Optional LED Display
In addition to short-circuit protection (SCP), overvoltage protection (OVP), and overcurrent protection (OCP), over-temperature protection (OTP) is provided as standard, ensuring safe operation even during peak power use. An LED display (optional) is available to enhance visibility of operating status and output information. Choose from two enclosure variations: UHDEI3045 P Series and UHDEI3045/LED P Series.
5) Four Output Voltage Models from 12.0V to 24.0V
Four output models ranging from 12.0V to 24.0V: 12.0V 3.8A (peak 6.8A, efficiency 87.74%), 15.0V 3.0A (peak 5.4A, efficiency 87.73%), 19.0V 2.3A (peak 4.2A, efficiency 87.70%), and 24.0V 1.8A (peak 3.3A, efficiency 87.69%).
6) EMC Compliance for Home Appliances (EN55014, BS EN55014)
EMC standards comply with CE CISPR14 EN55014-1, BS EN55014-1 (emission), EN55014-2, and BS EN55014-2 (immunity) for home appliances. It also supports FCC Part 15 Class B and VCCI Class B, covering domestic and international EMC standards required for appliance certification.
