An Endurance Laser box ver 2.0



An Endurance Laser box ver 2.0 


Key features of an Endurance MO2 PCB:
1. Analog input 0-10 PWM output 0-100%.
2. TTL input up to 24V PWM output.
3. Focusing mode laser PWM 0.1%.
4. Adjustable laser voltage threshold of 4.5 to 5.5V
5. Protection against reverse polarity reversal of analog, comparator and TTL inputs.
6. The delay in applying the voltage to the laser when the unit is turned on 1.5 sec.
7. Ability to install both large and small box without modifications of the printed circuit board.
8. Ability to run an impulse mode with a wide variety of frequency and duration width.
