Views : Update time : 2021-08-25
Wisepower's A3 model 12V1A power adapter is a high-performance Indian standard product; It can meet all assessment indicators of the Indian market at this stage and the requirements of future Indian Standards for EMC; The product has small volume and light weight; Sufficient consideration has been given to the saving of space; It is a power adapter product that can not be missed!Details are as follows:
1. Structural features and advantages
The product adopts the structural form of hardware horizontal + small ears exposed on both sides: it is not only beautiful, but also can make full use of the space for row and insertion, can well meet the requirements of safety regulations, and prepare for the slimming of the upper part of the adapter.

2. Main performance characteristics of the product
1. The product meets and obtains the Indian bis certification, meets the altitude of 5km, meets the EMC requirements and has sufficient margin, so as to consider the EMC requirements in the subsequent Indian market in advance（ (as shown below)
2. The energy efficiency at the end of the product line far exceeds the energy efficiency V standard. Appropriate upgrading can meet the VI standard.
3. The product bis certification temperature is 45 ℃ ambient temperature, and the actual product temperature rise and fall allowance is large (as shown in the figure below), which can meet the harsh high temperature environment in the Indian market.
4. The switching device of the product has large voltage withstand derating margin, and the front-end capacitor adopts 450V high-voltage capacitor to ensure that the product meets the harsh power grid fluctuation in the Indian market and ensures the reliability of the product to the greatest extent（ (as shown in the figure below)
