SKU: W120 power supply Categories: , ,


The W series CO2 laser power supply is a kind of adjustable power supply for laser cutting and engraving machines. Power supplies W120, W150, W200 are the most stable power supplies and allow wide use of CO2 laser tubes from any well-known manufacturers
high power factor, effectively resist the effect of large changes in mains voltage on the output current.
Self-contained digital LCD display can control the output light, output light, protection signal, water, can indicate normal and faulty signal, built-in potentiometer can manually regulate the current. The size of the mounting hole for the digital LCD display is the same as the current meter of the original design, i.e. no additional installation required. This laser power supply has TTL signal indication, can quickly detect whether the laser tube is damaged or the laser power supply is damaged, which greatly facilitates on-site maintenance.
The power supply meets a high level of security: it has an open circuit protection function, which greatly extends lamp life, simple laser power control can be controlled by 0~5V analog signal, or can also be controlled by 5V PWM signal. The power supply has a “TEST” button, which can manually test the output laser, and can also be used to test the working current of the laser tube.
All products pass ISO9001 and CE quality certification
Aging testing is carried out at the manufacturer’s factory. Each power supply undergoes pre-sales aging testing at 65°C under full load conditions for 10 hours and cycled on/off 300 times within 7 seconds
