DSP CO2 Laser Controller Power Requirements
Posted: Sun Mar 14, 2010 12:55 pm
How many amps are required on the 24v and 5v rails?
5V: 350mA so 500mA DC powe supply is necessary
24V: should be 1A but I need to test it and will post it here
24V can be share power with the stepping motor power supply. In that case, the size of the powe supply of the 24V depends on the type of motor(s) you use. For a 2.5A motor, you better get a PS for at least (2x 2.5A: X,Y motor + 1A: controller + 2x 1A: driver) 8A. To avoid overhaul, allow 20% margin. So, a 24V, 10A PS should be used.
