1. GENERAL DESCRIPTION
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 Q­Series).
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.

INTENDED USE
The decoupling module shall only be installed and put into operation by qualified personnel. This decoupling module is designed for installation in an enclosure and is intended for the general use, such as in
industrial control, office, communication, and instrumentation equipment. Do not use this device in aircraft, trains and nuclear equipment, where malfunctioning of the power supply may cause severe personal injury or threaten human life.
TERMINOLOGY AND ABREVIATIONS
PE and symbol PE is the abbreviation for Protective Earth and has the same meaning as the symbol .
Earth, Ground This document uses the term “earth” which is the same as the U.S. term “ground”.
T.b.d. To be defined, value or description will follow later.
DC 24V A figure displayed with the AC or DC before the value represents a nominal voltage with
standard tolerances (usually ±20%) included. E.g.: DC 12V describes a 12V battery disregarding whether it is full (13.7V) or flat (10V)
24Vac A figure with the unit (Vac) at the end is a momentary figure without any additional
tolerances included.

The Lifetime expectancy shown in the table indicates the operating hours (service life) and is determined by the lifetime expectancy of the built-in electrolytic capacitors.
Lifetime expectancy is specified in operational hours. Lifetime expectancy is calculated according to the capacitor’s manufacturer specification. The prediction model allows a calculation of up to 15 years from date of shipment.
MTBF stands for Mean Time Between Failure, which is calculated according to statistical device failures, and indicates reliability of a device. It is the statistical representation of the likelihood of the unit to fail and does not necessarily represent the life of a product.

22. APPLICATION NOTES
22.1. RECOMMENDATIONS FOR REDUNDANCY
Recommendations for the configuration of redundant power systems:
• Use separate input fuse for each power supply.
• 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 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 mains circuits.
• Use both inputs in parallel for currents above 10A.
22.2. 1+1 REDUNDANCY UP TO 10A
1+1 Redundancy up to 10A requires two 10A power supplies and one YR2.DIODE decoupling module.

N+1 Redundancy with 20A requires three 10A power supplies and two YR2.DIODE decoupling modules.
Please note: The DC-ok signal on the DIMENSION Q-Series 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.

22.5. BATTERY BACK-UP
A battery back-up with 10A requires one 10A power supply and one YR2.DIODE decoupling module.
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!

22.7. DECOUPLING OF BUFFERED BRANCHES
Buffer energy supplied from a DC-UPS or buffer module is not wasted in “power branches”. 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.

22.8. USE IN A TIGHTLY SEALED ENCLOSURE
When the decoupling module is installed in a tightly sealed enclosure, the temperature inside the enclosure will be higher than outside. The inside temperature defines the ambient temperature for the decoupling module.
Results from such an installation: Power supply is placed in the middle of the box, no other heat producer inside the box Enclosure: Rittal Typ IP66 Box PK 9516 100, plastic, 110x180x165mm
Load: 24V, 16A; (=80%) load is placed outside the box Input: 24Vdc Temperature inside enclosure: 57.8°C (in the middle of the right side of the power supply with a distance of 2cm) Temperature outside enclosure: 24.6°C Temperature rise: 33.2K

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 Recommended output current. Curve A2 Max allowed output current (results approx. in half the lifetime expectancy of A1).
