12/24V 80W Blue Laser Driver Board W/ TTL DIY CNC Laser Engraving Machine Module

Description: Product Parameter 1. Input voltage: Compatible with 12V and 24V DC input. 2. Adjustable current: external 5V PWM voltage signal, the signal duty cycle determines the output current, 0-3.5A corresponds to a duty cycle of 0-100%. 3. PWM signal description: Frequency range: 100HZ-30KHZ. 4. Over-temperature protection: Over-temperature regulation current, when the core temperature of the driver board reaches about 135 ℃, it will automatically reduce the output current. Prevent the circuit from being burnt due to excessive temperature. 5. Overcurrent protection: Abnormal overcurrent occurs, and the current in the circuit is quickly reduced to a safe level, thereby protecting the circuit and the load. 6. Dimensions: 40*40mm. Note: The voltage of the FAN interface is equal to the input voltage, so you need to pay attention when using this interface. PaymentDelivery detailsTerms of salesAbout usContact us Payment 1.
