14 Operating modes
Depending on the intended use, the power supply can be
run in series or parallel operation.
14.1 Series operation
To double the output voltage, connect two power supplies in
series. Only use power supplies with the same performance
class and configuration for series operation. If two 24 V DC
power supplies are connected in series, an output voltage of
48VDC is available to supply the loads.
Figure 29 Schematic diagrams in series operation
14.2 Parallel operation
You can connect several power supplies in parallel in order
to increase the power or to supply the loads redundantly.
Figure 30 Schematic diagram in parallel operation
Observe the following points when carrying out parallel
connection:
1. Use power supplies of the same type and performance
class
2. Setting power supplies to “parallel operation” via the
QUINT POWER software or QUINT POWER app
3. Setting the same output voltages
4. Using the same cable cross sections for wiring
5. Using the same cable lengths for the DC convergence
point
6. Operating power supplies in the same temperature
environment
7. When three or more power supplies are connected in
parallel, each output must be protected (e.g.,with
circuit breakers, fuses or decoupling modules)
