7. HOLD-UP TIME
The hold-up time is the time during which a power supply’s output voltage remains within specification following the
loss of input power. The hold-up time is output load dependent. At no load, the hold-up time can be up to several
seconds. The green DC-ok lamp is also on during this time.

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.
Switching hysteresis Typically 0.7V
Contact ratings Maximal 60Vdc 0.3A, 30Vdc 1A, 30Vac 0.5A, resistive load
Minimal permissible load: 1mA at 5Vdc
Isolation voltage See dielectric strength table in section 18.
