LM338K Adjustable Voltage Stabilized Power Supply Board Adjustable Voltage Stabilizer Module Adjustable Linear Voltage Stabilize

Description

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), when the input and output DC voltage difference exceeds 10V, please ensure that the output current is <2A, and the 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 because the brand new domestic LM338K, the output current will not exceed 2A and it will burn.

As an excellent linear regulator, LM338K has the characteristics of high stability, high temperature resistance and high linearity. The output voltage range can reach 1.25V~30V continuously adjustable, and the maximum working current exceeds 3A (the maximum output current can reach 5A needs to increase the heat sink or increase the active heat dissipation measures). The board is equipped with 8A rectifier bridge (with heat sink), and is equipped with 4400uF input filter capacitor and output 2200uF output filter capacitor, 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 low internal resistance and low ripple power.
