LED LM317 Step Down Power Supply Module Adjustable Voltage Regulator Input DC 0V-30V AC 0V-30V Output DC 1.25V-28V 2A
    
Description
Improved type: The LM317 adjustable DC stabilized power supply board listed in 2017, which uses a lotus-shaped heat sink for better heat dissipation. Change the dual-adjustment potentiometer. AC/DC can be input. Voltage input range: DC: 3-30V, AC : 3-20V.
It can be connected to loads below 2A, and the output is continuously adjustable from 1.25V to 28V, with a wide range of applications.
This board uses high-quality materials: imported LM317 Philips capacitors carry forward the rectifier bridge carry forward the diode
Circuit board size: length 68MM width 50M
note:
This power supply is a step-down module. If the input is greater than the output, a voltmeter below 4.5V will display abnormality, the output voltage is normal, and the quality of the non-voltmeter is a problem.
Package Included
1 Pcs LM317 adjustable voltage regulator step-down power supply module
