  Product Features
  1. Support 9-50V wide voltage input, synchronous rectification and efficient conversion, low heat generation and low loss
  2. MPPT solar charging intelligently tracks the maximum power point to improve the conversion efficiency of solar panels
  3. Constant voltage and current function, meeting the precise charging needs of different battery packs and loads
  4. High current output meets the power supply needs of high-power devices, with strong driving capability and excellent stability
  5. Widely applicable to industrial equipment, outdoor energy storage, and DIY electronic projectsProduct parameters:
  Module type: Non isolated synchronous rectification and voltage reduction module
  Input voltage range: DC 9-50V
  Output voltage range: DC 1.2-48V (factory voltage random, please adjust upon receipt)
  Adjustable range of output current: 0.1-15A MAX (recommended for long-term operation within 10A, please strengthen heat dissipation for high temperatures)
  Minimum voltage difference between input and output: Input voltage * 0.1 (the larger the output current, the more voltage difference there will be)
  MPPT voltage setting range: 9-50V (MPPT function can be used as input undervoltage protection)
  Operating frequency: 120KHz
  Overcurrent protection: starting at around 17A
  Charging indicator light: Yes (charging red light, fully charged green light)
  Input reverse protection: None (connected to reverse fuse and protective diode)
  Output anti backflow protection: None (please be sure to add an anti backflow diode when charging the battery, otherwise it will burn the chip)
  Conversion efficiency: up to 96% (efficiency is related to input/output voltage difference and output current)
  Fan interface: 12V 0.3A without temperature control
  Working temperature: -20~+85 ℃Note
  1. The module current detection is low-end detection. Please do not short-circuit the input negative terminal and output negative terminal of the module directly with wires.
  2. When connecting the output to a battery or supercapacitor, be sure to add an anti backflow diode, otherwise it will burn the module chip.
  When supplying power to valuable items using non isolated voltage reduction modules, please confirm the output voltage first; Please add an overvoltage protection module to the output to prevent module damage and load burnout.Package Included
  MPPT voltage reduction module * 1 (optional style)
