The laser power supply adopts zero-current half-bridge soft-switching circuit, which makes the power supply have high efficiency, fast response, simple port control and adapt to high and low level signals. The laser can be started and stopped by TTL level, Protect the light, testing whether the external water, ventilation and so on. Laser power adjustment can input 0 to 5V analog signal, you can also enter the PWM signal to control the size of the laser power. Each power supply will undergo a full-load state of 65 degrees 10 hours aging test, 7 seconds open power test 300 times
