100W class also available in wall-mounted type | Commercial AC adapter without AC cord required

  • NEW
  • PRODUCT

The 100W class AC adapter has been transformed into a wall-mounted type that plugs directly into the outlet. Unifive has published the selection points for the UNVG series (45W, 65W, 100W) featuring next-generation power semiconductors on its official website. 【For those considering a replacement from desktop models】 - Eliminates the AC cord, allowing for a review of total costs including material costs and packaging - Compact and lightweight design results in a tidy setup around the equipment - Contributes to the reduction of materials used and packaging, improving transportation efficiency - Standard operating temperature range of 0 to 40°C, with consideration for EMC performance We can also discuss semi-custom temperature ranges based on load conditions and evaluations while integrated into the equipment. Please inquire about selection, sample evaluation, and specification adjustments based on your current power supply specifications. For comparison tables and detailed explanations, please refer to the official article below. The applicability and compatibility of each model will be confirmed individually.
