8. DC-OK RELAY CONTACT
This feature monitors the output voltage on the output terminals of a running power supply.
Contact closes As soon as the output voltage reaches typ. 90% of the adjusted output voltage level.
Contact opens As soon as the output voltage dips more than 10% below the adjusted output voltage.
Short dips will be extended to a signal length of 100ms. Dips shorter than 1ms will be ignored.
Contact ratings max. 60Vdc 0.3A, 30Vdc 1A, 30Vac 0.5A resistive load
min. 1mA at 5Vdc min. permissible load
Isolation voltage See dielectric strength table in section 18.

9. SHUT-DOWN INPUT
This feature allows to switch-off the power supply output with a signal switch or transistor.
16
15
Shut-
down
Input
A link between pin 15 and 16 turns the power supply off.
Pin 15 is referenced to the (-) output voltage.
The open-loop voltage between pin 16 and pin 15 can be up to 18V, the maximum current, when
activating the shut-down, can be up to 2.5mA.
The threshold level to switch-off the output is typically 5V and the turn-on threshold is typically 9V.

15
Shut-
down
Input
When multiple power supplies are connected in parallel, pin 15 and pin 16 are also allowed to be
paralleled to control all units with the same switch or transistor.
Please note: The shut-down function has no safety feature included.
