                  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.

                  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
