CW Arc Lamp Drivers

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: series high voltage unit for igniting the lamp, LC unit
to relay the power, and low –voltage-constant-current to continue the lamp current.
Automatic igniting is achieved with igniting-detecting circuit. The successful ratio of onetime 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. Conveniently turns switch to Run/Stop status, adjust output current, and
show the working status through the inner/outer control selection.
Excellent design makes the power supply maintained easily and perfect design of circuit
protects the device from over voltage, over current and over heat.
There are the following advantages of our products:
High reliability
Advanced design of the whole circuits system highly improves the electrical
characteristics of the power supply.
Anti-dust design
Anti-vibration design
Easy maintenance
Malfunction indicators
Strict testing and 48hour full-load testing in the factory
Temperature test in -10℃~70℃ to ensure that it works stably in the ambient
temperature at 0℃~50℃.
Test in relative humidity 90%.
Measure the current ripple and test the stability of the output current accurately in
factory to make sure the output current meet the requirements of the Kr lamp.
