LM338K állítható feszültségű, stabilizált tápegységkártya, állítható feszültségstabilizátor modul, állítható lineáris feszültségstabilizátor
LM338K Adjustable Voltage Stabilized Power Supply Board Adjustable Voltage Stabilizer Module Adjustable Linear Voltage Stabilize
Electrical parameters:
Input voltage range: DC5V-35V, AC5V-22V
Output voltage range: DC1.25V-30V (continuously adjustable)
Output current range: maximum continuous working current <3A (input and output DC voltage difference does not exceed 10V), please ensure output current <2A when input and output DC voltage difference exceeds 10V, peak current can reach 5A
Operating temperature range: 0°C-100°C (in order to prevent over-temperature damage, you can increase the heat dissipation by yourself or use other active heat dissipation methods)
Dimensions (length, width and height): 86mm X 48mm X 32mm
Note: The voltage regulator LM338K of this board is a disassembled part. Please note that it is a brand-new domestic LM338K, and the output current will not exceed 2A and it will burn out.
As an excellent linear regulator, LM338K has the characteristics of high stability, high temperature resistance and high linearity. 5A needs to increase the radiator or increase the active cooling measures). The board is equipped with an 8A rectifier bridge (with heat sink), and is equipped with an input filter capacitor of 4400uF and an output filter capacitor of 2200uF, which can effectively reduce output ripple and interference. It is suitable for electrical appliances, equipment, audio, digital power amplifiers, etc. with power supply below 30V, and provides power with low internal resistance and low ripple.
