Laser Power Supply

The laser power supply incorporates a zero-current half-bridge soft-switching circuit, ensuring high efficiency and fast response, easily compatible with various laser tubes from different manufacturers. The laser power supply is well worth buying because: the ports can be easily controlled to adapt to high and low level signals; the switch can be controlled by TTL electrical level; and the abnormal protection switch can test external water supply, ventilation, etc. And it is often used as industrial laser power supply, laser cutting machine power supply, laser engraving machine power supply, etc.

Features
Top quality: the materials are strictly selected (the major parts are imported); the 30W-150W laser power supply has passed multiple standard tests, low-temperature test, full-load and high-temperature tests, etc. Great compatibility: the laser power supply is compatible with various sealed-off CO2 laser tubes from different manufacturers. Fast response speed: the excellent speed attributes to great engraving and cutting performance and significantly extends the laser’s service life. Simple and easy control: it can be controlled to adapt to high and low level signals or switched on/off by TTL electrical level; laser power can be easily controlled by 0-5 V analog signal or PWM (pulse width modulation) signal. Useful safety functions: the abnormal protection switch can test external water supply, ventilation, etc; in the well-grounding circumstance, the CO2 laser power supply can work under open circuit state within a short time to avoid damages caused by laser tube burst. Premium special functions: there is no need to unpack the power cover to tell whether it is working in proper operation, so it is easy to locate where the problem is when it occurs. Wide applications: the power supply is ideal for engraving and cutting on artwork and craft, PMMA, leather, cloth, rubber and other materials.
