Utility Requirements
Provide enough room cooling capacity to remove this waste heat and prevent the system from
overheating. Provide at least 6 inches of unobstructed space around the front and 8 inches at the
rear panels of the QPS to allow cooling air to enter the front and heated air to exhaust from the
back. The power supply draws 200 CFM of air flow.
Feature
Specifications
AC Power input
190 to 240 VAC (15 Amp service)
Maximum power consumption (EOL)
2200W
The Quasar Laser will NOT operate on 110VAC
The circuit must be capable of delivering 15 Amps. You must use two separate 15 Amp circuits
for the chiller and controller.
The QPS power supply incorporates double-pole neutral fusing for operation from 190 to 240
VAC. These two fuses are located on the rear panel of the power supply and can be accessed using
a standard screwdriver. Replacement fuses must be size 5 x 32 mm and of same type and rating
as below.
