CD10.482
CD-Series
DC/DC Converter 48V/48V, 5A, 240W
PRELIMINARY
3. DC-INPUT
The input can be powered from batteries or similar DC sources and must be a PELV or SELV source or an "Isolated
Secondary Circuit" in order to maintain a SELV or PELV output.
Check for correct input polarity. The device will not operate when the voltage is reversed.
DC input Nom. DC 48V ±25%
DC input range Min. 36-60Vdc Continuous operation
Allowed voltage between input
and earth/ground
Max. 60Vdc or
42.2Vac
Continuous operation, according to IEC 62477-1
Allowed input ripple voltage Max. 10Vpp In the frequency range from 47 to 500Hz, the
momentary input voltage must always be within the
specified limits.
Turn-on voltage Typ. 35Vdc Steady-state value, see Fig. 3-1
Shut-down voltage Typ. 31Vdc Steady-state value, see Fig. 3-1
Input current Typ. 5.3A At 48Vdc input and 48V, 5A output load, see Fig. 3-3
Typ. 7.0A At 36Vdc input and 48V, 5A output load, see Fig. 3-3
Start-up delay Typ. 350ms See Fig. 3-1
Rise time Typ. 50ms At 48V, 5A constant current load, 0mF load capacitance,
see Fig. 3-2
Typ. 150ms At 48V, 5A constant current load, 5mF load capacitance,
see Fig. 3-2
Turn-on overshoot Max. 500mV See Fig. 3-2
Input capacitance Typ. 1 650μF Installed inside the device, external capacitors on the
input are allowed without any limitations.
External input protection See recommendations in chapter 2.
