In-rush current
Although LED fixtures are low power devices compared to their incandescent equivalents,
their power supplies exhibit a trait known as ‘in-rush current’ when they are first powered
on. This is caused by the various components within the switching power supplies topping
themselves up with power. The in-rush current period lasts only milliseconds and does not
cause any effect when a handful of units are powered on at the exact same time. However,
if many fixtures are linked to the same power input, they will momentarily pull a current that
may greatly exceed their normal operating level. This may affect over-current trips when
power is applied. For this reason it is advisable to limit the number of fixtures on any one
power input.
