Notes:
(1) Values must be defined via RS232 digital interface. Minimum current must be above laser diode threshold.
Maximum current 25A with 7.5 V and 16A with 11.5V or maximum power of ~185W
(2) Rise time of <=100µs on request by optimized regulation parameters for a given operating current and voltage up to 21A.
Current overshoot could be as high as 15% for <50µs, but will not damage the diode.
Fall time is always shorter than or equal to rise time.
(3) External interlock must be a low current (<1mA) sourcing (mechanical) switch (e.g. door lock).
Notes:
(1) Operating temperature and rel. humidity must be chosen in a way that the dewpoint of humid air is below the temperature of the board to
avoid condensing of water.
(2) Electrical output power above 60W or 10A requires forced air cooling by 50 m3/h or 2 m/s along the plane of the board.
(3) EN60601-1-2 under evaluation.
