DC 24V A value that is displayed with the AC or DC before the value represents a nominal voltage

with standard tolerances (usually ±15%) included. For example: DC 12V describes a 12V

1+1 Redundancy

Use of two identical power supplies in parallel to provide continued operation following

most failures in a single power supply. Isolate the two power supply outputs from each

other by using diodes or other switching arrangements. For example, two 10 A power

supplies are needed to achieve a 10 A redundant system.

N+1 Redundancy

Use of three or more identical power supplies in parallel, which are allowed to be

connected in parallel for higher output currents, to provide continued operation following

most failures in a single power supply. Isolate all power supply outputs from each other by

using diodes or other switching arrangements. For example, to achieve a 40 A redundant

system, five 10 A power supplies are needed in an N+1 redundant system. Confirm that the

power supplies are allowed to be connected in parallel to increase the output power.

Single Input Redundancy Module - 12…28V, 40 A Reference Manual

Product Overview The 1606-XLSREDS40HE 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 40 A. The output is equipped

with a plug-connector, which allows for replacement

of the power supply or redundancy module while the

system is running (hot swapping).

The novelty of this redundancy module is that it uses

mosfets instead of diodes to decouple the output,

which helps reduce 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 slender and

only requires 46 mm (1.81 in.) width on the DIN rail.

Large connection terminals provide a safe and fast

installation. The large international approval

package makes this module suitable for nearly every application.

Product features:

• Single input with single output

• Equipped with plug-connector for 'hot swapping'

• Suitable for all 1606 power supplies except 1606-XLS960E-3 and

1606-XLS960F-3

• Only 150 mV voltage drop at 40 A

•Only6.2Wat40A

• 160% (65 A) peak load capability

• Reverse input polarity protection

• Full power between -40…+60 °C (-40…+140 °F)

• Width only 46 mm (1.81 in.)

• Rugged metal housing

Lifetime Expectancy and

Mean Time Between Failure

Terminals and Wiring The terminals are IP20 fingersafe constructed and suitable for field wiring.

To connect the chassis to the ground, use a ring-type terminal (ring cable lug)

that is suitable for an M4 screw. Connect this terminal to the chassis ground

terminal on top of the unit.

Wiring rules:

• The external circuitry of all terminals must meet the safety requirements

stipulated by IEC/EN/UL 60950-1: SELV.

• Use appropriate copper cables that are designed for minimum operating

temperatures of:

- 60 °C (140 °F) for ambient up to 45 °C (113 °F)

- 75 °C (167 °F) for ambient up to 60 °C (140 °F)

- 90 °C (194 °F) for ambient up to 70 °C (167 °F) minimum

• Do not connect or disconnect wires from the terminals below -25 °C

(-13 °F)

• Follow national installation codes and installation regulations.

• Verify that all strands of a stranded wire enter the terminal connection.

• Unused terminal compartments should be securely tightened.

• Ferrules are allowed.

Lifetime expectancy(1)

(1) The Lifetime expectancy values that are shown in the table indicate the minimum operating hours (service life) and are determined

by the lifetime expectancy of the built-in electrolytic capacitors. Lifetime expectancy is specified in operational hours and is

calculated according to the manufacturer specification of the capacitor. The manufacturer of the electrolytic capacitors only states

a maximum life of up to 15 years (131,400 h). Any number that exceeds this value is a calculated theoretical lifetime, which can be

used to compare devices.

MTBF(2) SN 29500,

IEC 61709

(2) Mean Time Between Failure (MTBF) 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 value

is a statistical representation of the likelihood of a device to fail. An MTBF value of, for example, 1,000,000 h means that statistically

one unit fails every 100 hours if 10,000 units are installed in the field. However, it cannot be determined if the failed unit has been

running for 50,000 h or only for 100 h.

Instructions to Insert and Remove the Pluggable Outlet Terminal

To avoid an accidental disconnection of the output, the plug connector is

equipped with a locking system.

To remove the latch mechanism, perform the following steps.

1. To unlock the red sliders, push the tabs down (A in Figure 5).

2. While pushing down, slide the tabs forward (B in Figure 5).

3. Pull out the connector to unplug it (C in Figure 5).

4. To inset the plug connector, reverse the above steps.

Figure 5 - Remove the Latch Mechanism

Replace Units While the

System Is Running

To replace the power supply or redundancy module while the system is

running, perform the following steps.

1. Switch off the circuit breaker (3a or 3b in Figure 6).

2. Remove the plug (4a or 4b), which helps prevent the cables from shorting.

3. Change the power supply (1a or 1b), or the redundancy module (2a or 2b),

or both (1a/2a or 1b/2b).

4. Reinstall the plug (4a or 4b).

5. Switch on the circuit breaker (3a or 3b).
