Strobe Relay Driver Module and Strobe Light Connection
5.4.2 Cable Sizing
It is inadvisable to use a wire gauge appreciably heavier than the gauges in the table(below) – there may be
problems with high inrush currents (which are required to charge the large electrolytic capacitors in some strobe
lights) which can weld the relay contacts. It is also recommended that you don't use cables shorter than 100m, or
if you do then add resistor(s) to make enough total resistance to give about a 10% voltage drop at the intended
load current.
It is recommended that cables are no longer than 1000m.
NOTE: The above paragraph does not apply if all strobes connected to a cable pair are Multi-Candela
strobes – as they do not suffer from the inrush current problem.
