100% Brand New and High Quality
 
Note: The AC input need to add the transformer.
 
Product description:
 
This circuit is made of common 317 rectifier filter voltage regulator circuit, optimized wiring, component symmetrical layout, arranged in a compact, beautiful and generous. Suitable for use with some small current devices.
 
Specifications:
 
PCB board size: 2.7CM × 7.5CM
Plate thickness: 1.6mm KB Kingboard A grade FR4 sheet
 
Power supply requirements:
 
Input AC voltage: below AC24V
 
Output DC voltage range: 1.5V<- (AC × 1.4 times = maximum DC) -> maximum 35V
 
Output DC current: up to 1.5A
 
Instructions for use:
 
1: This PCB power board is buck regulator circuit board, itself without boosting effect. Such as 18V AC rectification is 25V DC, then its maximum adjustable voltage is 25V.
 
2: the factory output voltage by default into a positive and negative 5V, the buyer can receive the goods after the need to adjust the voltage, adjust the method to find 3296 fine-tuning components, left twist for buck, right twist for the boost.
 
3: "AC IN" for the AC input, "+ - OUT" for the DC output, the installation of attention to distinguish between input and output, must not be reversed, will not burn LM317 op amp block.
 
Package Included:
 
1 x Rectifier Filter Power Assembled Board
