LM317 Adjustable Voltage Regulator Step Down Power Supply Module LED Meter AC DC Input
Specification:
- Input: DC 0V ~ 30V / AC 0V ~ 22V
- Output: DC 1.25V ~ 28V
- Output current: 2A Max.
- Digital dosplay: 4.5-28V (no display when less than 4.5V)
- Weight: About: 51g
- Circuit board size: 69 x 50 x 27mm ( L x W x H )
Description:
- Board core components: adjustable regulator ASIC LM317, 2A or less can be loaded, AC or DC voltage input, the output voltage is 1.25V-28V DC continuously adjustable, versatile DC board.
- Using double adjustment potentiometer: when using LM317T for adjustable power supply, often lead to output voltage increases
and burned the load due to potentiometer poor contact. We designed this regulator board using double potentiometer to ensure good contact, effectively protect the load.
Note:
- Due to the digital voltage display module operating voltage is 4.5V, only when the voltage is higher than 4.5V to display properly
- Power input must be higher than the output voltage above 3V to be regulated, buck, but cannot boot. When input 5V, can output 1.25-2V.
Package included:
- 1 x LM317 Adjustable Voltage Regulator module
