Turn on the chiller and adjust the temperature setpoint to 18 °C to 22 °C. Regulate coolant flow
to 1.5 GPM at less than 60 PSI of pressure.

Closely examine all cooling connections and verify that there are no leaks.
Electrical connections
DC power supply
SYNRAD power supplies, models DC-1, DC-2, and DC-5, are sized to power 48-1, 48-2, and 48-5 lasers
respectively. The 48-1 laser requires a SYNRAD DC-1 or equivalent power supply capable of providing
30 VDC at 7 A maximum; the 48-2 laser requires a SYNRAD DC-2 power supply (30 VDC at 14 A
max.); and the 48-5 requires a SYNRAD DC-5 power supply (30 VDC at 28 A max.).
If substituting power supplies, use a well-regulated DC power supply in the range of 30 V to 32 V with no
more than 3 V overshoot under a 10–90% modulation load. The use of short leads and terminations
rated for the appropriate output current is recommended.
Note: SYNRAD lasers are tested to meet published specifications at an input voltage of 30 VDC.
AC input power requirements for the DC-1 power supply are 85–264 VAC, single phase (1Ø), 20 A
max, 47–440 Hz. Input requirements for both DC-2 and DC-5 supplies are 90–132 VAC (low range)
or 175–264 VAC (high range), single phase (1Ø), 13 A (DC-2) or 25 A (DC-5) max, 47–440 Hz.
DC-1 power supply
To connect the DC-1 power supply, refer to Figure 1-5 and perform the following steps:

Inlet cooling water temperature must always be maintained above
the dew point to prevent condensation and water damage to your
laser.
