EFR power supply adopt zero-current half-bridge soft-switch circuit to ensure its high efficiency,rapid respone speed.
EFR laser power supply can be used for CO2 laser tubes 60W,80W,100W,120W,130W,150W. Its input voltage can be AC220V or AC110V.
Each power supply before being sold will go through the ageing tests, which is made at tempareture 65 °C with full-load condition and sustains 10 hours, is turned on/off 300 times within 7 seconds.
Features:
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 tube's operating current.
4. Power supply itself 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 power supply's working lifespan will be prolonged.
