Product Description

Power Supplies for CO2 laser tubes

EFR power supplies for CO2 laser tubes adopt zero-current half-bridge soft-switch circuit to ensure the equipment has advantages of high efficiency, rapid response speed and simple port control, and applicable to two signals high and low level. TTL level is to control the laser on/off, in the meantime, the power supply has an anomalistical protective switch to check whether the outer water and air, etc. are free or not. Adjust the laser power: Input imitative signal, from 0 to 5V, or PWM signal to control the output laser power Ageing test before leaving the factory： Each power supply before sold will go throuth the ageing tests, which is made at tempareture 65ºC with full-load condition and sustains 10 hours, is turned on/off 300 times within 7 seconds Main features of EFR Power Supply: 1、Excellent compatibility . 2、Extending the lifespan of the laser tube 3、Power supply has a feedback port, which can be used for closed-loop control and also for checking the laser tubes operating current. 4、Power supply iteself has a protection while in open-circuit state: Under the outer shell of the power is well connected with the ground, the power supply can be used in open-circuit state within a short time so as to avoid damaging the power supply when the laser tube leaks. Furthermore, the poewr supplys working lifespan will be prolonged.
