The core is LM317 plus TL431 as the reference, and Toshiba high-power transistor 2SA 1943 with higher accuracy and better stability, lower noise, good capacitance, high-speed tube, BI adjustable resistor, NOVER 10000UF filter, output with LC filter to further eliminate high frequency noise.
Note that this is a linear power supply, not a switching power supply. When the 4-5A current is output, there must be a certain temperature, which is completely normal.
Size: 130*250*60mm.
Net weight: 2.36kg.
Weight after packing: 3.2kg.
