CO2 Laser Power Supply for Laser Engraving Machine - High Efficiency from China Suppliers and Factory
Product Details
Modular Design with Automatic Detection
The system features a modular design, which enhances flexibility and ease of maintenance. It is capable of automatically detecting both the laser power signal and water protection status. This ensures that the system can monitor the performance of critical components and alert the user to any irregularities, such as insufficient water flow or power fluctuations, providing a safeguard for the overall system's operation. The self-diagnostic capability reduces downtime and ensures continuous, reliable performance during operation.
Zero-Current Semi-Bridge Soft Switch Circuit
The power supply integrates a zero-current semi-bridge soft switch circuit, which plays a key role in optimizing energy efficiency and responsiveness. This innovative design minimizes switching losses, ensuring that the system operates with maximum efficiency while maintaining a fast response time. The soft switching mechanism significantly reduces electromagnetic interference (EMI) and extends the lifespan of the components, contributing to overall system stability and long-term reliability.
Simple Port Control with TTL Signal Compatibility
The control ports of the system are designed for simplicity and ease of integration, making it compatible with both high and low-level signals. Using a TTL-level signal, users can easily control the start and stop of the laser, offering precise control over the laser's operation. Additionally, the system includes an abnormal protection switch that monitors external water and air flow, ensuring that the necessary cooling and ventilation systems are functioning correctly, preventing damage due to overheating or insufficient airflow.
Adjustable Laser Power with Analog or PWM Signal Input
It can be adjusted the laser power though the 0 to 5V analog signal ,but also to input PWM signal to control the laser power.
Open Circuit Protection Function
The power supply has the function or open circuit protection. In the case of good grounding,the power supply can work in the open state for a shor time to avoid the damage caused by the burst of the laser tube.
Rigorous Testing for Reliability
Each power supply must be tested in 60℃ in a fuIl load condition and switched 500 times in 7 second.
