800W 30A High Power CV CC Adjustable MCU DC-DC Step Down Buck Converter Module For Solar Power Charging

 

Main Parameters:
- Product name: high-power step-down module
- Input voltage: DC 20-70V
- Input current: 20A Max
- Output voltage: DC 2.5-58V
- Output current: 30A Max.
- Output power: 800W Max.
- Standby current: ≤70mA (input 24V, output 12V) corresponding to different voltages, the standby current is different.
- Output ripple: ≤120mV. Input 24V, output 12V/20A
- Conversion efficiency: 0.92-0.96
- Circuit structure: no isolation
- Working temperature: -20 to 50℃
- Dimensions: 154*75*69mm
- Product net weight: 550g

Features:
- This module uses high-performance original electronic components, the overall performance is more stable.
- Wide input and output voltage range, high output current and high power.
- Input low voltage protection (when the input voltage is lower than 20V, turn off the output).
- Output constant voltage and current, continuously adjustable voltage and current.
- There are output current test points, you can use a multimeter to test the value of the output current setting in the mV gear.
- There is an external voltage and current analog signal input terminal, which can be controlled by MCU to adjust voltage and current.
- There is an external output switch signal terminal.
- The input terminal Mos tube anti-reverse connection function, the product will not burn out when the input terminal is connected to the reverse polarity.
- Intelligent temperature control fan, when the temperature of the module rises, the fan starts about 55℃, and the temperature of the module decreases, and the fan shuts down about 50℃.

Applications:
- This module can be used to input high-voltage batteries and charge low-voltage batteries (Batteries are not included).
- Various occasions requiring high voltage drop to low voltage and high current.
- Solar step-down charging.
- DIY a step-down DC adjustable module, you can replace the original adjustable with an external adjustable (voltage 100K current 1K), easy to use. The external adjustable must be wound with good quality multi-turn wire. Poor quality will damage the module, and the external wiring should not exceed 15cm.

Package Included:
- 1 x Step Down Module
