Note: At no load, the hold-up time can be up to several seconds. The green DC-ok lamp is also on at this time.
9. DC-OK Output
This feature monitors the output voltage, which is present on the output terminals.
The signal is a source output which can feed loads up to 30mA. Loads can be a 24V relay (Rcoil < 700Ohm), a LED or
the input of a PLC system. The relays operates or the LED is on if output voltage exceeds the threshold level.
A wheeling diode (necessary when the load is a relay) is already included in the power supply.
Threshold value 20V +/-4%
Output current min. 30mA For typical values see Fig. 9-2
Output voltage min Vout – 1V
at 30mA
The open collector is internally linked to the positive output pole. The
DC-OK voltage is approximately the output voltage if the output voltage
is higher than the threshold level.
