U
in
= 300 - 824 V DC: Rated power (480 W) and Extra Power (150 % for 5 s/min)
U
in
= 200 - 300 V DC: Operating range with current derating max. 10 A (2 min. max.)
U
in
= 824 - 860 V DC < 1 min permissible (1x in 1 min.)
U
in
= 860 - 900 V DC < 10 s permissible (1x in 10 min.)
In the operating range from 824 - 900 V DC, the complete output power (20 A) is available within the
specified times.
Between 824 and 860 V, the output voltage is continuously available, if a linear derating of 1 A per
10 V is taken into consideration.
U
in
> 900 V DC: The output voltage is shut down
U
in
> 975 V DC can damage the device
