LM317 LM337 ±1.5-35v Adjustable Rectifier Regulator Power Supply PCB Board
Description:
Large electrolysis uses 35V3300uF, 3A rectifier bridge
Adopt the new ON LM317/LM337
Input voltage: AC5-25*2V
Output voltage: DC±1.5-35v
Whole page output current: 1.5A
Printing board size: 79*61mm, 2mm thick printing board, 70um thick copper foil
Input voltage requirements:
Generally, the voltage difference after the input voltage is rectified should be 6~10V higher than the output voltage.
[Calculation formula: input AC*1.414-output DC= 6-10V]
The relationship between the output DC voltage and the secondary AC voltage of the transformer is as follows:
Output: when ±5VDC, the transformer selects 2*9VAC
Output: when ±9VDC, the transformer selects 2*12VAC
Output: when ±12VDC, the transformer selects 2*15VAC
Output: when ±15VDC, the transformer selects 2*18VAC
Output: when ±18VDC, the transformer selects 2*20VAC
Output: when ±24VDC, the transformer selects 2*25VAC
Package including:
1PCS * Power Supply PCB Board
