Output circuit decoupling
diodes required for 100%
redundancy
All power supply units from Phoenix Contact, which can be connected in parallel, are
dimensioned in such a way that an internal short circuit in the secondary circuit is virtually
impossible. This means that for parallel connection of multiple power supply units no
decoupling diodes are required in the output circuit. External diodes are only needed for a
100% redundancy and when more than two units are required.
The following example shows unnecessary power dissipation when using decoupling
diodes:
A 40 A QUINT POWER power supply unit has an efficiency of 92% and a maximum power
dissipation of 75 W at nominal load. There is a voltage drop across the decoupling diode
of 1 V, approximately. The product of voltage and current results in a power dissipation of
40 W. The total power dissipation for the power supply unit with decoupling diode thus
increases to 115 W, i.e., 53%. At the same time, the efficiency is reduced to 88%.
For redundant circuits monitoring of the individual power supply units is recommended in
order to detect any failure.
