Power Supplies For ES Series

Power Supplies For ES Series

EFR laser power supply adopts zero-current half-bridge soft-switching circuit, which makes the power supply have high efficiency, fast response speed, simple port control, and adapt to high and low level signals. The use of TTL level can control the start and stop of the laser. Abnormal protection switch is added to check whether the outside of the water, ventilation and so on.

Laser power conditioning can input analog signals from 0 to 5V, or PWM signals can be used to control the laser power.

Each power source will undergo a 65 hour high temperature 10 hour aging test under full load condition, and 7 seconds power supply test 300 times.

 

Characteristics of Es series laser power supply:
1. active PFC function, AC90-250V ultra wide input voltage range, universal, no need to worry about input voltage mismatch.
2. the shell adopts a special design, the appearance is more stable, beautiful, heat dissipation is better, can better reflect the characteristics of industrial products.
3. the improved current control mode is more stable and compatible, and is suitable for all types of laser tubes.
4. the cabinet is small and suitable for mounting on the cross beam of the cutting bed.

Compared with E series power supply:

  • The full tie regulator function, 110, 220V general, can adapt to the global voltage range, to eliminate power damage caused by voltage instability, greatly reduce the failure rate of the power supply.
  • The shell is made of precision mould, which has higher strength, better heat dissipation and scratch resistance.
  • Compared with the E series, the improved current control mode has more stable light output and better compatibility.
