Input nom. DC 600V
-20%/+40%
Input range min. 480-840Vdc Continuous operation
min. 360-480Vdc Maximal 60s or with reduced output current, see Fig. 5-2
min. 840V-900Vdc Maximal 60s or with reduced output current, see Fig. 5-2
max. 1000Vdc Absolute maximum input voltage with no damage to
the DC/DC converter. Above 900Vdc, the output will
switch off and will turn-on again, when the input
voltage falls below 850Vdc.
Allowed voltage input to Earth max. 600V R.M.S. Continuous, IEC 60664-1
max. ±900Vpk Peak value, allowed for transients
Slew rate for voltages between
input and Earth (ground) max. 1000V/μs
Allowed input ripple voltage max. 50Vpp 50Hz-40kHz
Turn-on voltage typ. 450Vdc Steady-state value, load independent, see Fig. 3-1
Shut-down voltage typ. 325Vdc Steady-state value, load independent, see Fig. 3-1
Input current typ. 0.79A At 24V, 20A, see Fig. 3-3
Start-up delay typ. 350ms See Fig. 3-2
Rise time typ. 70ms At 24V, 20A, only resistive load see Fig. 3-2
typ. 110ms At 24V, 20A, resistive load with an additional 20mF
capacitor
Turn-on overshoot max. 500mV See Fig. 3-2
External capacitors on input Allowed without any limitations
