6 Overvoltage protection* (DC2412-UPS-LDD only)
Overvoltage peaks (Vin > 32 VDC…<123 V) can be intercepted by the device
for up to 400 ms.
If an overvoltage takes longer than 400 ms, the input is disconnected and the backup
function starts. Power Fail is activated.
After switching off by overvoltage, the input must be disconnected or interrupt to
restart the device (Latch).
This is done by disconnecting and reconnecting the supply voltage.
* „Load Dump“ function
7 Charging time of Supercaps
The main part of the current is transferred to the output, a smaller part is used to charge
the Supercaps. At low loads there is correspondingly more charging current available and
the charging time is shorter.
Charging time without load <60 s
Charging time at full load app. 2 ½ minutes
8 Behaviour during overload / short circuit
The device is protected against polarity reversal, overvoltage* and overload. In case of
an overload, the device switches off and recovers automatically as soon as the output
current is within the specified range or the overload no longer exists.
