*) Up to 4s of overloading, the power supply delivers continuous output current. After this, the output power is reduced to nearly zero for
approx. 17s before a new start attempt is automatically performed. If the overload has been cleared, the device will operate normally. If the
overload still exists, the output current will be delivered for 2 to 4s (depending on the overload) again followed by a 17s rest time. This cycle
is repeated as long as the overload exists.
The red overload LED is permanently on when the overload current is continuously flowing. During the 17s rest period, the red LED is
flashing with a frequency of approx. 1.3Hz.
