are redundant power source systems and separation of sensitive loads from non-sensitive loads, which can
distort the power quality of the 24V bus and causes controller failures.

Application Notes

Recommendations
for redundant
applications:

1+1 Redundancy

up to 10A output current

Utilization of two 10A
power supplies and one
YR2.DIODE.

• Use separate input fuse for each power supply.

• Use Three-phase power supplies to gain functional safety if one

phase fails.

• When Single-phase power supplies are utilized connect them to

different phases or circuits.

• It is desirable to set the output voltages of all power supplies to

the same value to avoid a false signal of the DC-ok signal.

• Use both inputs in parallel for currents above 10A.

Utilization of two 20A
power supplies and two
times the YR2.DIODE.

N+1 Redundancy

Example: 20A output
current

Utilization of three 10A
power supplies and two
YR2.DIODE.

The DC-ok will only work
properly if the adjusted
output voltage of each
power supply will be
reached after turning-on
the input power. A power
supply operating in current
limiting mode will result in
a DC-fail condition.
Read notes in the
individual power supply
datasheets.

Battery backup

10A output current:

Set output voltage of
power supply to 26.5Vdc
minimum to avoid that the
charger current flows to
the load instead of
charging the battery.

Use a fuse between
battery and YR2.DIODE!

Decoupling of

Buffer energy supplied
from a DC-UPS or Buffer
Module is not wasted in
“power branches”.

Set output voltage of the
power supply to a level
that the buffer unit or DC­UPS will not start
unexpected. Take the
voltage drop of the
