Protections
11.
The power supply includes various protections that prevent damage to the LD.
External interlock
External interlock function provides multiply protections at the same time:
Prevents inadvertent use;
Allows to connect an external emergency switch;
Allows to connect an external auto protect device (
e.g. over-temperature switches
).
The laser can only be turned on with shorted
Interlock
.
Soft-start
The soft-start function protects against unwanted overshoot of the LD in the power up process.
LD max current limiting
LD max current limit (
LD max current
) is described in paragraph 15.7. You cannot set the
operating current above LD max current.
Laser diode temperature protection window
This function protects the LD from unwanted temperature in combination with a thermal
controller. If you set the temperature window limits close to the set temperature, the laser can be
turned off permanently (the measured temperature will be outside the LD temperature window).
