Product description
LDD90 semiconductor laser system output 12A/7.5V (constant current adjustable) semiconductor laser drive, 60mA (constant current is not adjustable) indicating light drive; LD drive full load output current ripple <100mA, current ramp time> 5ms, current slow down Time >5ms; foot switch controls LD drive output; touch display shows chassis temperature, LD drive output voltage, LD drive output current; touch screen can control indicator light drive output, LD drive output mode selection (continuous pulse mode / single Sub-pulse mode / continuous mode), pulse width setting; potentiometer can adjust semiconductor laser drive output current; hardware over-current protection, over-temperature protection, external emergency stop protection and other protection functions.
Interface introduction
Front panel interface as shown:
1 Product Name: LDD90 Semiconductor Laser power supply System;
2 Emergency stop button: After the emergency stop, the system will no longer output, release the emergency stop and re-power on the normal output;
3 Touch display: can detect the chassis temperature, output current, laser operating voltage, select LD drive output mode, pulse width setting, B output switch;
4 Current adjustment knob: adjustable LD drive output current, clockwise increase, the maximum adjustment current 12A;
5 Company Name: Shandong Laser Source Technology Co., Ltd.
Rear panel interface as shown:
1 Output and control interface:
1 foot - LD+
2 feet - indicator light +
3 feet - LD-
4 feet - indicating light -
5-6 foot - foot switch
2 System fan; chassis cooling fan, please keep the vents open;
3 AC input: input voltage is 90~260VAC, 50/60Hz, the switch is set to 1 position and the system is energized, the 0 position system is powered off;
4 Ground studs: connect the earth;
Touch screen interface introduction
1 Continuous pulse mode: In this mode, after the foot switch is closed, the LD drive continuously sets the current waveform output with the pulse width as the output time and 3 times the pulse width as the cycle;
2 Single pulse mode: In this mode, after the foot switch is closed, LD drives to set the pulse width as the current waveform of the output time, and then no longer outputs;
3 Continuous mode: In this mode, after the foot switch is closed, the LD drive will always output until the foot switch is released;
4 LD driving power working status display: Gray indicates LD drive has no output, red indicates LD drive has output;
5 Indicating light switch: when it is pressed, it turns red to indicate that the light driver has an output, and click again to turn off the indicator light to drive the output;
6 Chassis temperature: Real-time display of chassis temperature;
7 Output voltage: real-time display LD drive output voltage;
8 Output current: real-time display LD drive output current;
9 Pulse Width Setting: In the continuous pulse mode and single pulse mode, the pulse width can be set and the setting range is 50~999ms; this function can only be set when the foot switch is released;
