4.3 Charge Characteristic/Output Power Diagram
The charge characteristic of the PSR327 is a power limited IV characteristic curve in accordance with
DIN 41772/DIN 41773.
For modules in parallel operation mode a load sharing of about ±10% is attained due to a sloping output
voltage line (-1% at 100% Inom).
The module is continuously short circuit proof.

(example PSR327/48-56)
Calculation of the output current (Io) at different output voltage values using the PSR327/48-65 being
the example:
The PSR327 rectifier provides an output power of Vonom x Ionom= Ponom (48V x 56.25A= 2700W).
As shown with the output power diagram (see figure 6), the nominal output current (56.25A) is available
at the nominal output voltage (48.0V).
At other output voltage values (e.g. float or boost charge voltage), the output current is corresponding
to the following formula: Io= Ponom : Vo
Example 1):
Float charge voltage for lead acid batteries (24 cells) = 54.5V; Io= 2700W : 54.5V= 49.5A
Example 2):
Boost charge voltage for lead acid batteries (24 cells) = 57.6V; Io= 2700W : 57.6V= 46.9A
