ESCRIPTION
The YRM2.DIODE is a redundancy module, which can
be used for various purposes. The most popular
application is to configure a highly reliable and true
redundant power supply systems. This redundancy
module has a monitoring circuitry included. Two
LEDs and two relay contacts signal when one of the
two DC-input voltages is not in range due to a non-
functioning or disconnected power supply.
Another interesting application is the separation of
sensitive loads from non-sensitive loads. This avoids
the distortion of the power quality for the sensitive
loads which can cause controller failures.
Alongside with the YRM2.DIODE, there exists the
decoupling
module
YR2.DIODE
monitoring circuitry included. This is the perfect fit
when the power supply itself is already equipped
with a DC-OK signal (e.g.: DIMENSION Q-Series).

Please note: Set output voltage of the power supply to a level that the buffer unit or DC-UPS will not start unexpected. Take the voltage drop of the YRM2.DIODE into account. -
Page 17: Mounting Orientations
YRM2.DIODE 24-60V, 20A, D Y-Series EDUNDANCY ODULE Mounting Orientations Mounting orientations other than vertical require a reduction in continuous output current or a limitation in the max. allowed ambient temperature. The amount of reduction influences the lifetime expectancy of the power supply. Therefore, two different derating curves for continuous operation can be found below: Curve A1 Recommended output current.
