Chapter 5 Operation Guide
CAUTION :
◎
The main power supply (24VDC) must be able to provide continuous
operating current (see detailed specifications in Chapter 4) and
Peak current higher than 50% in 250us short cycle. Most types of lasers have a
current loss of less than 10A, so their peak current loss is less than 14A.
◎
The power supply should maintain a stable voltage and be within the specified
range (see Chapter 4 for detailed specifications). If the up and down fluctuations
of the power supply voltage exceed the specification range, the laser operation
will be unstable. Please pay attention to the transient load variation rate of the
power supply and choose an appropriate power supply type.
◎
When the main power of the laser is connected, the voltage drop (especially
the peak current loss) caused by the length and cross section of the laser's own
power cord can be ignored.
◎
The 24VDC main power supply must have a floating output, and its return line
can only be connected to the laser power line (blue). Incorrect connection may
cause current loops to fail.
◎
The laser ground (DB25 Pin10-15,24) and the laser 24VDC power return
line (blue line) are connected to the inside of the laser module, and the external
interface of the laser module is not allowed to be connected.
◎
The common ground inside the module is connected to the laser case through
