EDUNDANCY
Power supplies can be paralleled for redundancy to gain higher system availability. Redundant systems require a certain amount of extra
power to support the load in case one power supply unit fails. The simplest way is to put two power supplies in parallel. This is called a
1+1 redundancy. In case one power supply unit fails, the other one is automatically able to support the load current without any
interruption, see also chapter 22.5.
Please note:
This simple way to build a redundant system does not cover failures such as an internal short circuit in the secondary side
of the power supply. In such a case, the defective unit becomes a load for the other power supplies and the output voltage can no
longer be maintained. This can be avoided by utilizing redundancy modules, which have decoupling devices (diodes or MOSFETs)
included. Further information and wiring configurations can be found in chapter 21.3.
Recommendations for building redundant power systems:
a)
Use separate input fuses for each
power supply.
b)
Monitor the individual power supply units.
Therefore, use the DC-OK relay contact of the YRM2.DIODE.
c)
It is desirable to set the output voltages of all units to the same value (± 100mV) or leave it at the factory setting.

PERATION
Power supplies of the same type can be connected in series for higher output voltages.
It is possible to connect as many units in series as needed, providing the sum of the
output voltage does not exceed 150Vdc. Voltages with a potential above 60Vdc are no
longer SELV and can be dangerous. Such voltages must be installed with a protection
against touching.
Earthing of the output is required when the sum of the output voltage is above 60Vdc.
Avoid return voltage (e.g. from a decelerating motor or battery) which is applied to the
output terminals.
Keep an installation clearance of 15mm (left / right) between two power supplies and
avoid installing the power supplies on top of each other. Do not use power supplies in series in mounting orientations other than the
standard mounting orientation (input terminals on bottom of the unit).
Pay attention that leakage current, EMI, inrush current, harmonics will increase when using multiple power supplies.
