Technical data
10.2 Technical data of the G115D wall-mounted converter
10.2.6.3
Current derating as a function of the line voltage
The converter operates at 100% rated output current at a line voltage from 380 V to 480 V.
The permissible converter output current is reduced linearly when the line voltage is above
480 V.
10.2.6.4
Current derating as a function of the pulse frequency
The permissible converter output current is reduced when the converter is operated at a
pulse frequency above 4 kHz.
The pulse frequency reduces automatically based on the heatsink temperature.
