Hold-up Time
For extended hold-up time, use external output capacitors
or decoupling diodes and input capacitors of adequate
size.
Formula for additional external input capacitor
C_{i ext} = –2–•–^P–_η–^o–••–((_V–^th–_ti2t–^o_–^t–^al–_V^––_i –_m^th–_in^)–₂^{•)–1–0–0–}
where as:
C _{i ext}
P_o
η
= external input capacitance [mF]
= output power [W]
= efficiency [%]
t_{h total} = total hold-up time [ms]
t_h
= hold-up time [ms]
V_{i min} = minimum input voltage [V]
V_{t i}
= threshold level [V]
All outputs have a constant current limitation with a
rectangular characteristic (see figure below). The total
current from the main power trains Vo1, Vo2 and Vo3 is
limited by P_{o max}. So there is a free choice of load
distribution between these outputs.

Hot Swap
Hot swap is possible. Using the hot-swap capability, the
0
I_o
output voltages may deviate dynamically by max. 5%
during the plug-in / plug-out operations.

Output Protection and Current Limitation
Current limitation behavior of a CPD.
The outputs are fully protected against continuous open
circuit (no load) and also against continuous short circuit.
