DC 0-100V 20A 1000W LED Digital DC Step-Down Voltmeter Buck Constant Voltage Current MPPT Solar Energy Battery Power Supply

   Feature:

   1: Wide range of applications

   2: A variety of working modes are optional

   3: Enlarge the heat sink, install a smart fan, strengthen heat dissipation, and reserve another 5V interface for the fan, which is convenient for adding fans and strengthening heat dissipation.

   4: Using synchronous rectification technology, high conversion efficiency

   5: It has a variety of software protection mechanisms, and the protection threshold can be adjusted. After the working parameters of the module exceed the protection threshold, the output will be automatically turned off

   Description:

   1. Various working modes are available: DC-DC power supply and battery charging working mode

   2. MPPT solar charging mode.

   3. Dedicated charging interface for output: The relay is physically isolated to prevent reverse connection of the reverse, and the charging is safer. Intelligent switching of various charging modes.

   4. Automatically shut down when fully charged and the input voltage power is insufficient, and automatically recover when the battery voltage is insufficient or the input power increases.

   5. Over-temperature, over-power, over-voltage, over-current and other protections are turned off.

   6. Timing, fixed capacity automatic shutdown.

   7. MPPT solar charging, automatic tracking of maximum power, improve charging efficiency.

   8. Various interface displays: LCD can display input voltage/output voltage/temperature, output current/output power/output capacity/output time;

   9. Numerical control constant voltage and constant current adjustment, accurate and fast, step-down output, output voltage 0-100.00V can be adjusted arbitrarily. When the voltage output setting is less than 50V, the limited current can be adjusted arbitrarily from 0 to 20.00A; when the voltage output setting is greater than 50V, the limited current can be adjusted arbitrarily from 0 to 10.00A.

   10. The module can be set to turn on/off by default, and the power-down parameters are saved.

   11. Has a variety of software protection mechanisms, and the protection threshold can be adjusted. When the working parameters of the module exceed the protection threshold, the output will be automatically turned off;

   12. Using synchronous rectification technology, the conversion efficiency is high.

   13. Enlarge the heat sink, install a smart fan, strengthen heat dissipation, and reserve another 5V interface for the fan, which is convenient for adding fans and strengthening heat dissipation.

   14. TTL serial port and input control IO are reserved to facilitate customization.
