Product Description

Function Description

Application Range: Suitable for LD laser driving, fiber lasers, laser marking machines, and high-frequency Q-switched lasers.

This power supply adopts a modular parallel design, built on a high-performance, high-precision, and high-efficiency constant current sub-module. By stacking n sub-modules, it can achieve arbitrarily high current output. Compared to traditional power supplies, this modular design offers several advantages:

1. Simple Structure with Flexible Current Output: Using a modular stacking structure allows for easy scalability of current output. Maintenance is convenient and efficient for customers.
2. High Precision and Efficiency: Leveraging the high-precision and high-efficiency characteristics of the sub-modules, the overall system inherits these advantages.
3. Enhanced Reliability: The mainboard includes overcurrent and overheat protection, ensuring the high reliability of the constant current source for semiconductor laser driving.
