Description

Dc 9A 300W Step Down Buck Converter 7-40V To 1.2-35V Power Module

This 10A Adjustable Constant Current Power Supply is designed for stable and precise current regulation, ideal for LED drivers. It features a dedicated reference IC and high-precision sampling resistor for minimal temperature drift and stable performance. The maximum output current reaches 10A, meeting most power needs. With 4 high-frequency capacitors to reduce ripple and a double heat sink design, it ensures efficient heat dissipation.

The system uses pure copper wires for better efficiency and heat reduction. The 3296 multi-turn potentiometer allows accurate voltage and current adjustment. It also includes a two-color indicator light to show the working status clearly. Adjustable voltage and current make this power supply versatile and reliable for various applications.

Technical Details 

  • Module Characteristics: Non-isolated step-down constant current, constant voltage (CV CC) charging module
  • Input Voltage: DC 7-32V
  • Output Voltage: 1.2V-28V adjustable, or fixed output 0.8V-28V
  • Output Current: 8A (cooling fan required if power tube temperature exceeds 65°C)
  • Constant Current Range: 0.2-8A (adjustable)
  • Turn Lamp Current: Constant current value * 0.1 (e.g., for 3A constant current, the lamp current is 0.3A)
  • Lowest Pressure: 1V
  • Output Power: Maximum 200W
  • Conversion Efficiency: Up to 95%
  • Operating Frequency: 300KHz
  • Output Ripple: 20M bandwidth
  • Ripple at 24V input, 12V output, 5A: Around 50mV (excluding noise)
  • Output Short Circuit Protection: Yes, constant current
  • Input Reverse Polarity Protection: None
  • Output Backflow Prevention: None
  • Wiring: Terminal
  • No-load Current: Typical 20mA (24V switch 12V)
  • Load Regulation: ± 1% (fixed)
  • Voltage Regulation: ± 1%
  • Dynamic Response Speed: 5% 200uS
  • Adjustment Direction Potentiometer: Clockwise to increase voltage, counterclockwise to decrease. CV adjusts input voltage, CC adjusts current.
  • Operating Temperature: -40°C to +85°C (industrial grade, with temperature considerations for power tube)
  • Indicator: Dual-color indicator (Red for charging, Green for fully charged, No load is green)
  • Size: 65x47x22mm (L x W x H)
  • Accuracy of Constant Current and Temperature: Less than 5% change in constant current value from 25°C to 60°C (5A constant current)

  • Input Reverse Connection Protection: No
  • Output Prevent Reverse Flow: No
  • Wiring Method: Amphenol connector

Features 

  • Turn lamp current is 0.1 times the current value for battery charge indication.
  • Stable constant current with <1% temperature drift, ideal for LED drivers.
  • Max output current: 8A.
  • High-frequency capacitors reduce ripple and improve stability.
  • Double heat sink design for effective heat dissipation.
  • Sendust Core and pure copper wiring for better efficiency and less heat.
  • Precise voltage and current regulation with 3296 multiturn potentiometer.
  • Dual-color indicator for clear working status.
  • Adjustable voltage and current for optimized performance.

Battery charge:  

  • Check the required battery float voltage, charging current, and module input voltage.
  • Adjust the constant voltage potentiometer to set output voltage to around 5V.
  • Use a multimeter (10A scale) to measure output short-circuit current and adjust the current potentiometer to the desired charging current.
  • Adjust the constant voltage potentiometer to match the float voltage.
  • Connect the battery and test the charging process. (Steps 1-4 should be done with no battery connected.)

LED constant current drive: 

  • Check the operating current and max operating voltage of the LED.
  • Adjust the constant voltage potentiometer to set output voltage to around 5V.
  • Use a multimeter (10A scale) to measure output short-circuit current, then adjust the current potentiometer to match the LED operating current.
  • Adjust the constant voltage potentiometer to reach the maximum LED operating voltage.
  • Connect the LED and test. (Steps 1-4 should be done with no LED connected.)

Applications :

  • High-Power LED Driver: Powers high-intensity LEDs for lighting and displays.
  • Lithium Battery (or Lead Accumulator) Charge: Charges lithium or lead-acid batteries in various devices.
  • Vehicle-Mounted Power Supply: Provides power to vehicles' electrical systems, including inverters and accessories.
