ESCRIPTION
The YR40.241 is a redundancy module, which can be used to build 1+1 and N+1 redundant systems. It is equipped with two input channels which can be connected to 20A power supplies and one output which can carry nominal currents up to 40A.
The novelty of this redundancy module is the utilization of mosfets instead of diodes for the decoupling of the two input channels. This reduces the heat generation and the voltage drop between input and output. The redundancy module does not require an additional auxiliary voltage and is self-sufficient even in case of a short circuit across the output.
Due to the low power losses, the unit is very slender and only requires 36mm width on the DIN-rail. Large connection terminals allow for a safe and fast installation with a large international approval package.
This unit is suitable for nearly every application.

*) The Lifetime expectancy shown in the table indicates the minimum operating hours (service life) and is determined by the lifetime expectancy of the built-in electrolytic capacitors. Lifetime expectancy is specified in operational hours and is calculated according to the capacitor’s manufacturer specification. The manufacturer of the electrolytic capacitors only guarantees a maximum life of up to 15 years
(131 400h). Any number exceeding this value is a calculated theoretical lifetime which can be used to compare devices.
**) 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 a unit to fail and does not necessarily represent the life of a product.

To connect the chassis, use a ring-type terminal (ring cable lug) which is suitable for a M4 screw and connect it to the chassis ground terminal on top of the unit.
Instructions: a) The external circuitry of all terminals must meet the safety requirements stipulated by IEC/EN/UL 60950-1: SELV. b) Use appropriate copper cables that are designed for minimum operating temperatures of:
60°C for ambient up to 45°C and
75°C for ambient up to 60°C and
90°C for ambient up to 70°C minimum. c) Follow national installation codes and installation regulations! d) Ensure that all strands of a stranded wire enter the terminal connection! e) Up to two stranded wires with the same cross section are permitted in one connection point. f) Screws of unused terminal compartments should be securely tightened. g) Ferrules are allowed, but not required. h) Do not connect or disconnect the wires from the terminals below -25°C (-13°F).

ECOMMENDATIONS FOR
R
EDUNDANCY
Recommendations for the configuration of redundant power systems:
•
Use separate input fuses 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 mains circuits if possible.
•
Set the power supply in “Parallel-Use” mode if this feature is available
•
It is desirable to set the output voltages of all power supplies to the same value.

LEARANCES
The minimum clearance recommendations are defined in chapter 2.
Normally, the following installation clearance are recommended: 40mm on top, 20mm on the bottom, 5mm on the left and right sides when the device is loaded permanently with more than 50% of the rated power. Increase this clearance to 15mm in case the adjacent device is a heat source (e.g. another power supply).
The clearance between the power supplies and the redundancy module can be reduced to zero under the following conditions:
•
1+1 redundancy application with maximum 20A output current.
•
The redundancy module is placed between the two power supplies.
•
The output voltage is set to the same level on both power supplies.

RIENTATIONS
Mounting orientations other than input terminals on the bottom and output on the top require a reduction in continuous output power or a limitation in the maximum 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:
Recommended output current.
Max allowed output current (results in approximately half the lifetime expectancy of A1).
