Brand: KNACRO

Model: LM317 Buck Voltage Converter

LM317 is three-terminal adjustable regulator integrated circuit early made by National Semiconductor and widely used in many integrated circuit manufacturers. Easily use , it just need two external resistance to set output voltage. Besides, its linear adjusting ratio and rejection ratio is better than the standard fixed regulators.

Package Includes:
1 x Parallel Type Voltage Regulated Power Panel

• KNACRO voltage converter input voltage range DC 0-35V/AC 0-28V, output voltage range DC 1.25-32V, can be continuously adjustable
• the highest short-circuit current can reach 4.5A.
• The power converter input power supply part adopts 6A flat bridge to create the bridge rectifier, it can input DC or AC power supply and no need to distinguish the positive or the negative.
• LOAD PROTECTION: KNACRO voltage regulator power module is with load protection, prevent regulator from ageing and damaged, which may lead to burn down as suddenly rising voltage.
• INTERNALl VOLTMETER: the buck conveter is with high precision digital display voltage meter, no need to use external multimeter.
• HEAT SINK: KNACRO power converter uses large volume heat sink, which is cooling well, more stable and durable.
