Laser LS8000-3 manual Quad Conductor Supply

LaserSpeed 8000-3 Instruction Handbook

Appendix D: Supply Voltage Requirements

In order to deliver at least 20 volts to the LS8000-3, your power supply will need to be greater than 28.2 volts. The supply should not be higher than 30VDC, or damage may occur.

Quad Conductor Supply

If you are using four conductors (two supply, two return wires), the following table will help you determine your total voltage drop across the cable.

Wire Size	Wire Size	Voltage Drop per Foot	Voltage Drop per Meter
(AWG)	(mm2)	(@2.0A)	(@2.0A)
26	0.129	0.082	0.27
24	0.205	0.051	0.17
22	0.326	0.032	0.11
20	0.518	0.020	0.067
18	0.823	0.013	0.042
16	1.31	0.008	0.026
14	2.08	0.005	0.017
12	3.31	0.0032	0.010

Example: Your power supply is 200 feet (61 meters) away from the LS8000-3 gauge. You are using two 20 AWG wires to supply power to pin 24 and 25, and two 20 AWG wire as a ground (connected to pins 12 and 13). Your voltage drop in the cable will be:

Voltage Drop = #Feet * Voltage Drop/Foot = 200 * .020 = 4 volts

In order to deliver at least 20 volts to the LS8000-3, your power supply will need to be at least 24 volts.

Note: All Beta LaserMike supplied cables have connections for quad conductor supply. In order to take advantage of all conductors, you need to be sure to supply power to both pins 24 and 25, and tie the two ground pins (12 and 13) together. The wires are not necessarily tied together inside the cable.
