1.Well-adapted：Includes active PFC circuit，achieve higher power factor，Meet the global universal input voltage range(AC90-264V,50/60Hz).Be valid to resist the affection to output current when the grid voltage changes greatly.

2.More Power：Ensure that the maximum current is constant at the entire input voltage range.

Patented technology Shell:Use patented technology shell，complies with industrial product standard, beautiful, durable, excellent heat dissipation performance.

3.ESA Series：（1）Can be equipped with liquid crystal display：：the number can shows the magnitude of current, the light indicator, the optical signalwater protection signal indicates signal normal and fault. Integrated potentiometer manually adjusts the current.. （2）The install hole are of the same size：The hole`size of LCD and the original pointer ammeter are the same, no need to drill the hole seperately.

4.Control the laser power is simple：can use 0~5V analog signal and 5V PWM signal to control power.

5.Power itself has open circuit protection：the use will be more secure，and can Prolong the life of power significantly.

6.More stable performance：Newly developed improved current control mode can make out light smoother and more compatible.

7.Good compatability：Can perfectly match vast most 50-150w CO2 Laser Machine at home and abroad also prolong the life of laser and power.

8.Power has manual light test button：Be convenient to test laser and power, easy to maintenance.
