Designed for reliable power conversion in various electronic applications, this module provides a stable 3.3 Vdc output with a maximum current of 0.5 A and a power rating of 2 W. It features a wide input voltage range from 36 to 75 Vdc, making it suitable for industrial, medical, and other demanding environments.
This DC-DC converter is ideal for use in industrial automation, medical devices, and other electronic systems requiring reliable power isolation and conversion over a broad input voltage range.
Additional Information
For detailed technical data, application notes, and integration guidelines, please refer to the datasheet.
Note: The datasheet was not processed; please search the internet for the part number PQA30-D48-S12-TH for more details.
I'm particularly impressed with how carefully the header pins are packed for the RP2350-PiZero, they arrived in perfect condition without any bent pins, which has been a persistent issue with other competitors. This attention to packaging detail really stands out.
I also received the latest A4 revision of the RP2350, which shows you maintain current inventory, that's really valuable for customers who want the most up to date components.
The delivery was quick and hassle free throughout. I'll definitely be recommending you to others!
App feedback: The discounts offered through the app are a nice bonus, but the component search function could be improved to match the ease of use on the website version. The rest of the app functions work well.
