LM338K 3A Voltage Digital Display High Power Adjustable Linear Module Buck Step Down Regulator

Parameter:

 

Board size: 9.6cm x 5.8cm

DC input: 3-35 volts

AC input: 1-25 volts

Output DC: 1.2-30 volts; kit weight: 155 grams

Maximum current: 3 amps, (LM338K theory can go to 5A, we use domestic LM338K, up to 3A, import disassemble up to 5A)

Input and output minimum differential: 3 volts

Maximum power consumption: 50W

 

About LM338K maximum power calculation:

 

For example, input 25V, output 18v load current 2A, then the power consumption on the LM338k is (25-18)x2=14w, LM338k power consumption can work normally within 50w. If it is input 36v, output 3v current 3A, then fall to LM338k The power consumption is (36-3)x3=99w, LM338k can't bear to work.

Features:

 

1. The output interface adopts the terminal block, which is convenient to connect.

2. Output with power main switch for easy debugging

3. Output with self-recovery fuse with short circuit protection

4. Input with rectifier circuit, AC or DC power input can be used, can be input without polarity

Package includes:

1 x Module
