Great Compatibility: Characterized by a high efficiency, frequency, and speed, the PS-N series CO2 laser power supply is a matched power supply for CO2 laser devices. With the great compatibility, it can easily and directly be connected to laser devices without a ballast.

High Efficiency: The laser equipment power supply features a high power transfer efficiency and can facilitate the start of the CO2 laser tube, enabling it to work properly, and ensure a prolonged service life.

Dual-Use Interface: The CO2 laser power supply is equipped with a dual-use interface, which can either be used to achieve closed-loop control, or to test the actual operating current of the laser tube.

Open Circuit Protection: The CO2 laser power supply for optical processing machinery can achieve open circuit protection. If the housing has a safe ground connection, the laser power supply can function on an open circuit for a short amount of time. This protection helps extend the service life of the laser power supply.

Thanks to a zero-current half bridge soft-switching current, the CO2 laser power supply has a high efficiency, short response time and easy interface control. It responds to signals sent by the TTL high/low level switch, and controls the switch on/off laser devices.

This laser power device is also equipped with a protection switch, which can effectively detect abnormal water and air ventilation. It can receive 0-5V analog signals, and a PWM signal to regulate laser power.

Aging Test: Each laser tube power supply must undergo a 10 hour, full-load operation under a 65℃ temperature. They must also undergo on/off switch tests every 7 seconds, and must do so 300 times.
