DC-OK Relay Contact (Quick-connect spring-clamp terminals)
The DC-OK relay contact is synchronized with the DC-OK LED.
See chapter 8 for details.
D Output voltage potentiometer
Open the flap to adjust the output voltage. Factory set: 24.1V
E
DC-OK LED (green)
On, when the output voltage is >90% of the adjusted output voltage
F Overload LED (red)
On, when the voltage on the output terminals is <90% of the
adjusted output voltage, or in case of a short circuit in the output.
Input voltage is required.

*) 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.
