We also support semi-custom solutions and assist with power supply selection from the specification planning stage for mass production adoption. |
Key Features
1) Compliance with home appliance safety standards (61558-1, 60335-1)
Complies with home appliance safety standards 61558-1 (General requirements for transformers and power supplies) and 60335-1 (Safety of household electrical appliances), as well as PSE Appendix Table 8. Designed for power applications in products requiring compliance with the 60335 standard, such as electric cooking appliances, fans, air conditioners, and air purifiers. For details on certification status of each model, please contact our sales department.
2) ErP Lot7 compliant models available with top-level energy efficiency
In addition to standard Energy Efficiency Level VI (ErP/DoE), models compliant with the European Ecodesign Directive ErP Lot7 are available. Compliance with Lot7, which sets stricter energy efficiency requirements than Level VI, enables support for applications demanding the highest level of energy savings and environmental consideration. For details, please contact our sales department.
3) Desktop enclosure with flexible installation options
Adopts a desktop enclosure with AC inlet input (75.0x50.6x29.8mm). Since the AC cable can be selected separately, flexible operation according to installation location and country of use is possible. Also suitable for stationary applications where wall-mount types are not ideal.
4) 5.0V-24.0V, 7 output voltage models
Seven output voltage models ranging from 5.0V to 24.0V are available to meet diverse home appliance power requirements: 5.0V 3.0A (efficiency 81.39%), 5.9V 2.8A (efficiency 81.98%), 9.0V 2.0A (efficiency 85.00%), 12.0V 1.5A (efficiency 85.00%), 15.0V 1.2A (efficiency 85.00%), 18.0V 1.0A (efficiency 85.00%), and 24.0V 0.75A (efficiency 85.00%).
5) EMC compliance for home appliances (EN55014, BS EN55014)
Complies with home appliance EMC standards: CE CISPR 14 EN55014-1, BS EN55014-1 (Emission), EN55014-2, BS EN55014-2 (Immunity). Also supports FCC Part15 Class B and VCCI Class B, covering domestic and international EMC standards required for product certification.
