BRZHIFI AC220V 120W DC Linear Power Supply Regulated Power Supply DC12V Output without Display
Description:
The 120W DC Linear Power Supply features one interface.
The core solution employs the LM317 and the TL431 as a reference, and utilizes the high-performance power transistor 2AS1943 for current amplification. Compared to common LT317 and LT1083 solutions, this configuration offers higher precision and better thermal stability. The addition of the TL431 as a reference voltage regulator elevates the performance by 1-2 levels. It also features lower noise and lower ripple. While the cost remains reasonable, we have incorporated high-quality capacitors and high-speed transistors. The BI (bias current) is adjustable, and the filtering is handled by a NOVER gold-grade 10,000μF capacitor. The output includes a 1-stage LC filter to further eliminate high-frequency noise.
It also features a high-current aviation output interface.
Package Included:
