The air-cooled v30 (SA) laser requires a DC power supply capable of providing 30 VDC at 15 A (24 A peak for a minimum
of 0.5 ms) while fan-cooled (SFE) lasers require 30 VDC at 16 A (24 A peak for a minimum of 0.5 ms). We recommend the
SYNRAD PS-2 a 30 V, 750 W DC power supply (shown in Figure 6). AC input requirements for the PS-2 power supply are
90–264 VAC (auto-ranging); single phase (1Ø); 10 A maximum; 47–440 Hz. To connect the PS-2 power supply, refer to
Figure 6 and perform the following steps:
Note: The negative (–) side of the DC input to the laser is internally connected so that the laser chassis serves as DC
power ground. You should isolate the laser’s DC power supply so that the only grounded connection is at the laser.
Alternatively, you can mount the laser chassis on an insulating pad or film in order to electrically isolate the laser
when other equipment is grounded to the laser’s DC power supply.

The customer-supplied fan shroud must be designed
so that it encloses both the OEM v30 laser and cooling fan.
