LM317 LM337 Dual Voltage Regulator Adjust Power Supply Module Converter DIY Kits Description: This is DIY Kits, you need solder its by yourself. Base on LM317 LM337 adjustable IC, in accordance with the original typical circuit design, stable and reliable. Filter capacitor using original ELAN 1800uF/25V gold fever capacitors, sufficient for most occasions. Voltage adjustment is multi-turn precision adjustable resistors can be transferred to their own needs more precise voltage. Supporting the radiator suitable for small current occasions, a large current output increased according to the situation radiator. Features: Input Voltage: Less than AC 18V (If you need to improve the operating voltage, only need to replace the higher voltage filter capacitor.) Output Voltage: 1.3V minimum (Max voltage= The voltage across the filter capacitor - 2.5V) Board Size: 74x52x39mm (LxWxH) Packing List: 1set x LM317 LM337 Dual Voltage Regulator Power Supply Module Kits |
