GENERAL DESCRIPTION

The YR40.245 is a redundancy module, which can be used to build redundant systems. The module has one input and one output and can carry nominal currents up to 40A. The output is equipped with a plug-connector, which allows replacing the power supply or the redundancy module while the system is running (hotswapping)

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.

Due to the low power losses, the unit is very slender and only requires 46mm width on the DIN-rail. Large connection terminals allow for a safe and fast installation. The large international approval package makes this unit suitable for nearly every application.

may A key word indicating flexibility of choice with no implied preference

shall A key word indicating a mandatory requirement

should A key word indicating flexibility of choice with a strongly preferred implementation

1+1 Redundancy Use of two identical power supplies in parallel to provide continued operation following most

failures in a single power supply. The two power supply outputs should be isolated from each other by utilizing diodes or other switching arrangements. E.g. two 10A power supplies are needed to achieve a 10A redundant system.

N+1 Redundancy Use of three or more identical power

supplies in parallel to provide continued operation following most failures in a single power supply. All power supply outputs should be isolated from each other by utilizing diodes or other switching arrangements. E.g.: To achieve a 30A redundant system, four 10A power supplies are needed in a N+1 redundant system.

*) 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.

The MTBF figure is a statistical representation of the likelihood of a device to fail. A MTBF figure of e.g. 1 000 000h means that

statistically one unit will fail every 100 hours if 10 000 units are installed in the field. However, it can not be determined if the failed unit has been running for 50 000h or only for 100h.

ZM12.SIDE Side mounting bracket

This bracket is used to mount the YR40.245 redundancy module sideways with or without utilizing a DIN-Rail. The two aluminum brackets and the black plastic slider of the unit have to be detached, so that the steel brackets can

be mounted. For sideway DIN-rail mounting, the removed aluminum brackets and the black plastic slider need to be mounted on

the steel bracket.

18. APPLICATION NOTES

18.1. RECOMMENDATIONS FOR REDUNDANCY

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.

18.2. INDUCTIVE AND CAPACITIVE LOADS

The unit is designed to supply any kind of loads, including unlimited capacitive and inductive loads.

18.3. SIDEWARDS INSTALLATION CLEARANCES

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 40A output current.

- The power supplies are from the PULS DIMENSION series.

- The redundancy module is placed between the two power supplies or at least on one side of the power supply.

- The output voltage is set to the same level on both power supplies.

18.6. MOUNTING ORIENTATIONS

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:

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