About this item

  • CAN BOOST AND BUCK: This boost/buck module can step up or step down voltage and maintain a stable output voltage, The step down regulator can apply to constant output current.
  • ULTRA LOW OUTPUT VOLTAGE: Voltage regulator has quite low output voltage, for example, 20mV when output is 12V 3A, which is great for powering speaker, audio amplifier, artificial circuit, etc.
  • DC MOTOR SPEED CONTROLLER FUNCTION: It supports input over-current , input under-voltage and MOS input anti-reverse .
  • CONSTANT CURRENT FUNCTION: Input 5V to 30V and it can storage battery, lithium battery, AA rechargeable battery, or adjust constant current LED brightness.
