Thermal management
To ensure operation within given specifications and for the warranty to be valid, the laser head must be mounted on
a suitable heat sink. The requirement on thermal resistance of the heat sink can be calculated by taking the difference
between the maximum allowed laser head base plate temperature (50 ºC) and the ambient temperature at the air-
heat sink interface (e.g. 40 ºC), divided by the maximum power dissipated from the laser (60 W). The laser head must
be attached to a heat sink providing a thermal resistance of < 0.17 K/W at 40°C. The mounting surface should be flat
within 0.05 mm over mounting surface. Under normal circumstances thermal heat compound is not required,
however if the laser is operated in an area with a high ambient temperature it is recommended to use a thermally
conductive compound between the laser head and the heat sink to provide good thermal contact. For assistance in
thermal management and system integration, please contact Cobolt’s technical support.
Heat Sink Requirements for Cobolt Skyra™.
Power supply requirements
An appropriate Power Supply Unit (PSU) is supplied by Cobolt with the laser and can be plugged into a standard power
outlet. The power supply accepts 90-264 VAC and 47-63 Hz. Ripple and noise 1% peak-peak max, 20 MHz bandwidth.
Accepted voltage range for the laser head is (12.0 ± 0.4) VDC. Specification values are given at 12 VDC.
The power
supply provided with Cobolt Skyra™ is certified to perform in an ambient temperature of 40°, when integrating this
power supply into a larger system care must be taken to ensure that the power supply is not exposed to temperatures
above 40°C.
