Feature: 1.The power supply adopts zero-current half-bridge soft switching circuit, featuring high efficiency, fast response and easy matching for laser tubes produced by various manufacturers. 2.Its ports can be controlled simply to adapt to high and low level signals; the switch of the laser can be controlled by TTL electrical level. Meanwhile, it has an additional abnormal protection switch to test external water supply, ventilation, etc.
3.The laser power can be adjusted by entering either 0 to 5V analog signals or PWM signals.
4.The power supply has open circuit protection function: under the well grounding circumstances, it can work under open circuit state within short term to avoid laser power supply damages caused by laser tube burst.
5.Ex-factory Aging Test:
Each power supply should go through 12-hour, 60°C high temperature aging test under full load with 500 times power supply switches in 7 seconds.
