Rated output voltage:
48 V dc
Output voltage at half load (25°C):
54.4 V dc ±0.5%
Nominal output current (I n):
8 A
It is possible to link a single output or both.
The maximum overall output current that can be supplied continuously (I max a) is given by:
I n: nominal output current (8 A)
C: battery capacity [A h]
The maximum overall output current can be supplied for a short period of time (I max b,
when battery charging is not in progress) corresponds to the nominal value (8 A).
PS 4048 can operate without an output load.
The maximum overall output current (8 A) can be drawn from an output or both.
