The YR2.DIODE is a decoupling module, which can

be used for various purposes. The most popular

application is to configure a highly reliable and true

redundant power supply systems.

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.

The YR2.DIODE is the perfect solution to use in a

redundant system, if the power supply itself is

equipped with a DC-OK signal (e.g.: DIMENSION Q-

Series).

Alongside with the YR2.DIODE, there exists the

YRM2.DIODE which has a monitoring circuitry

included. LEDs and relay contacts signal when one of

the two DC-input voltages is not in range due to a

non-functioning power supply.

Unique quick-connect spring-clamp terminals allow a

safe and fast installation and a large international

approval package for a variety of applications makes

this unit suitable for nearly every situation.

YR2.DIODE 10-60V, 20A, DUAL DECOUPLING MODULE Y-Series 22. APPLICATION NOTES 22.1. RECOMMENDATIONS FOR REDUNDANCY Recommendations for the configuration of redundant power systems: • • Use separate input fuse for each power supply. • • • Use Three-phase power supplies to gain functional safety if one phase fails. 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.

Please note: 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!

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 YR2.DIODE into account.

YR2.DIODE 10-60V, 20A, DUAL DECOUPLING MODULE Y-Series 22.9. 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 Curve A2 Recommended output current. Max allowed output current (results approx.
