• 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 using 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 using diodes or
other switching arrangements. E.g. to achieve a 40A redundant system, five 10A
power supplies are required in a N+1 redundant system.

Description
The 1606-XLSRED40 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 power supplies with up to 20A output
current and one output, which can carry nominal
currents up to 40A. The module is suitable for power
supplies with constant current overload behavior as well
as any kind of “Hiccup” overload behavior.
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-sufcient 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.

5. Lifetime Expectancy and MTBF
The redundancy module has two input channels which are completely independent from each other. Each control
circuit, auxiliary voltage source, or other circuitry in the module are designed separately for each input. The dual input
redundancy module can be considered as two single redundancy modules combined together in one housing. The only
common point is the circuit trace that ties the two separate circuits together at the output.
The MTBF gures below are for the entire dual input module. If the MTBF number of only one path is needed, simply
double the value from the table.

*) 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 specied in operational hours and is calculated according to the
capacitor’s manufacturer specication. 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 gure is a statistical representation of the likelihood of a device to fail. A MTBF gure of e.g. 1 000 000h means that
statistically one unit will fail every 100 hours if 10 000 units are installed in the eld. However, it can not be determined if the failed unit
has been running for 50 000h or only for 100h.

All parameters are specified at 24V, 40A output current, 26°C ambient and after a 5 minutes run-in time, unless noted otherwise.

17. Application Notes
17.1. Recommendations for Redundancy
Recommendations for the conguration 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.
17.2. Inductive and Capacitive Loads
The unit is designed to supply any kind of load, including unlimited capacitive and inductive loads.
17.3. Lateral Installation Clearances
The minimum clearance recommendations are dened in section 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:

17.6. 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
inuences 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).
