CW Laser Power Supply
The STCW series laser power supplies are made for CW lamp-pumped Nd:YAG lasers. The main circuit of the power supply is based on power electronic module IGBT, adopts PWM technique to yield conversion efficiency more than 90%, and outputs constant current with high accuracy and low current ripple.
Ignition circuits which produce a high voltage pulse consists of three steps The successful ratio of one-time ignition is more than 99%. The high voltage rises smoothly, and its magnitude can be adjusted to meet the dispersible characteristics of the krypton lamps, and to reduce the spattering of the electrode material at the same time, and further to reduce the damage to the krypton lamp caused by high voltage triggering.
The soft-charging circuit and soft-starting circuit are provided to avoid the voltage spiking and in-rush current in the event of starting. Display shows the set current and operation current at different time. The function of “work/sleep” is designed to output normal current at working and low holding current at the time of stand by, so as to increase the efficiency of the power supply, lighten the heat exchanger system, and prolong the lifetime of the lamp as well. The highly efficient switch-mode power supplies feature power-factor correction and universal line input capabilities. Backward compatibility is assured through the use of standard input/output connections.
Excellent design makes the laser power supply maintained easily and perfect design of circuit protects the device from over voltage, over current and over heat.
