The LR7843 MOSFET Control Module is a high-power switching module designed to replace traditional relays, providing faster response, longer lifespan, and higher efficiency. It uses the LR7843 MOSFET, known for its low Rds(on) resistance and high current handling capacity. This module is ideal for motor control, LED dimming, battery charging, and DC power switching applications.
Features of LR7843 MOSFET Control Module:
- Solid-state relay replacement with improved efficiency and durability.
- Supports PWM control, making it perfect for speed and brightness adjustments.
- Ultra-low on-resistance (Rds ON ≤ 1.4mΩ) ensures minimal heat generation.
- Optocoupler isolation for safe and stable operation.
- Compatible with microcontrollers such as Arduino, Raspberry Pi, and STM32.
Specifications of LR7843 MOSFET Control Module:
- MOSFET Model: LR7843
- Input Voltage (Control Signal): 3.3V - 20V DC
- Load Voltage: 5V - 36V DC
- Load Current: Up to 20A
- Trigger Signal: Low-level trigger
