24V, 40 A, Single-phase Input Power Supply
The Bulletin 1606-XLS DIN-rail power supplies are efficient and
small. Achieved by a synchronous rectification, a bridge-less PFC
circuit, and some additional unique design details.
Large power reserves of 150% and built-in large sized output capacitors
support the starting of heavy loads such as DC motors or capacitive
loads. The use of a unit from a lower wattage class can be used to save
space and cost.
High immunity to transients and power surges and low
electromagnetic emissions makes usage in nearly every environment
possible.
The integrated input fuse and the near zero input inrush current make
installation and usage simple. Diagnostics are easy due to the DC-OK
relay, a green DC-OK LED, and the red overload LED.
A large international approval package for various applications makes
this unit suitable for nearly every application.

Input Inrush Current
The power supply is equipped with an active inrush current limitation
circuit, which limits the input inrush current after turn-on to a
negligible low value. The input current is smaller than the steady state
input current.

(1) BonusPower®, short-term power capability (up to typ 4 s) The power supply is designed to support loads with a higher short-term power requirement without damage or shutdown. The short-term duration is hardware that is
controlled by an output power manager. This BonusPower® is repeatedly available. If the power supply is loaded longer with the BonusPower® than shown in the Bonus-time diagram (See Figure 8 on page 6), the max output
power is automatically reduced to 960 W. If the power requirement is continuously above 960 W and the voltage falls below approx. 20V (due to the current regulating mode at overload), the unit shuts-off and makes periodical
restart attempts. This behavior is called hiccup mode that is described below. If the voltage is above 20V, the unit continuously delivers current.

(2) HiccupPLUS Mode Up to 4 s of overloading, the power supply delivers continuous output current. After this, the output power is reduced to nearly zero for approx. 17 s before a new start attempt is automatically performed. If the
overload has been cleared, the device will operate normally. If the overload still exists, the output current will be delivered for 2s to 4s (depending on the overload) again followed by a 17 s rest time. This cycle is repeated as long
as the overload exists. See Figure 7 on page 6. During the off-period, a small rest voltage and rest current is present on the output.

Shut-down Input
This feature allows a switch-off of the output of the power supply with
a signal switch or an external voltage. The shut-down occurs
immediately while the turn-on is delayed up to 350 ms. In a shut-down
condition, the output voltage is <2V and the output power is <0.5 W.
The voltage between different minus pole output terminals must be
below 1V when units are connected in parallel. In a series operation of
multiple power supplies only wiring option “A” with individual signal
switches is allowed.

Remote Control of Output Voltage
The shut-down input can also be used to remotely adjust the output voltage between typically 22V DC and 28V DC. All other functions of shut-
down input remain the same.
The control voltage is referenced to the main ground (negative output voltage)
Internal Data Logging
A protected microcontroller inside the power supply acquires and stores operating data during the life of the unit. The data can be downloaded with
a small tool and special software by the Rockwell Automation service and repair personnel, even when the unit is non-operational. The data allows
for better troubleshooting. Analysis of what happened before a failure can be determined much more accurately.
Acquired Data
•Family name of unit (1606-XLS), revision of firmware
•Operational hours
•Expired portion of lifetime (combination of temperature and time)
•Maximum ambient temperatures with timestamp (max 47 values)
•Maximal input voltages with timestamp (max 47 values) and type of input voltage (AC or DC)
•Failure report (various internal errors)
•Number and timestamp of input overvoltage transients
•Number and timestamp of over-temperature shut-downs
•Number of turn-on sequences
The data will be acquired with a fixed sampling rate unless the peak detectors do trigger due to an abnormal condition. In such cases, the abnormal
condition will be captured. Furthermore, data will be acquired every time shortly before the unit switches off.

Attribute AC 100V AC 120V AC 230V Notes
Calculated lifetime expectancy(1)
(1) The calculated lifetime expectancy that is 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 (131 400 h). Any number
exceeding this value is a calculated theoretical lifetime that can be used to compare devices.

MTBF(2)
(2) MTBF represents 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, for example, 1 000 000h means that statistically one unit will fail 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 000h or only for 100 h.

Dielectric Strength
The output voltage is floating and has no ohmic connection to the ground. Type and factory tests are conducted by the manufacturer. Field tests
may be conducted in the field using the appropriate test equipment that applies the voltage with a slow ramp (2 s up and 2 s down). Connect all
input-terminals together and all output poles before conducting the test. When testing, set the cut-off current settings to the value in the table
below.
Figure 28 - Dielectric Strength
To fulfill the PELV requirements according to EN60204-1 § 6.4.1, we recommend
that either the + pole, the – pole or any other part of the output circuit shall be
connected to the protective earth system. This helps to avoid situations in which a
load starts unexpectedly or cannot be switched off when unnoticed earth faults occur.

Buffer Module
This buffer unit is a supplementary device for DC 24V power supplies. It delivers
power to bridge typical mains failures or extends the hold-up time after turn-off of the
AC power. In times when the power supply provides sufficient voltages, the buffer
unit stores energy in integrated electrolytic capacitors. In case of mains voltage fault,
this energy is released again in a regulated process. One buffer module can deliver 20
A. To buffer the full output current of 40 A, two buffer modules are needed in
parallel.
The buffer unit does not require any control wiring. It can be added in parallel to the load circuit at any given point. Buffer units can be added in
parallel to increase the output ampacity or the hold-up time.
WARNING: Risk of electrical shock, fire, personal injury, or death.
–Do not use the power supply without proper grounding (Protective Earth).
–Use the terminal on the input block for earth connection and not one of the screws on the housing.
–Turn power off before working on the device. Protect against inadvertent repowering.
–Make sure that the wiring is correct by following all local and national codes.
–Do not modify or repair the unit.
–Do not open the unit as high voltages are present inside.
–Use caution to prevent any foreign objects from entering the housing.
–Do not use in wet locations or in areas where moisture or condensation can be expected.
–Do not touch during power-on, and immediately after power-off. Hot surfaces may cause burns.

Redundancy Module
The cat. no. 1606-XLSRED80HE is equipped with two input channels (40 A each), which are individually decoupled by utilizing mosfet
technology. The output current can go as high as 80 A. Using mosfets instead of diodes reduces the heat generation and the voltage drop between
input and output. The 1606-XLSRED80HE does not require an additional auxiliary voltage and is self-powered even if there is a short circuit
across the output.
Due to the low-power losses, the unit is slender and only requires 46 mm width on the DIN-rail.
Redundancy Module
The 1606-XLSREDS40HE is a 40 A single channel redundancy module, which is equipped with a plug connector on the output. The plug
connector allows replacing the power supply or the redundancy module while the system is running. The plug connector avoids that the output
wires can touch and short the load circuit.
The1606-XLSREDS40HE is slender and only requires 46 mm width on the DIN-rail. It also utilizes mosfet technology instead of diodes for low
heat generation and a minimal voltage drop between input and output. It does not require an additional auxiliary voltage and is self-powered even if
there is a short circuit across the output
Application Notes
Repetitive Pulse Loading
Typically, a load current is not constant and varies over time. This power supply is designed to support loads with a higher short-term power demand
(=BonusPower®). The short-term duration is hardware that is controlled by an output power manager and is available on a repeated basis. If the
BonusPower® load lasts longer than the hardware controller allows it, the output voltage will dip and the next BonusPower® is available after the
BonusPower® recovery time has elapsed.
To avoid this, the following rules must be met:
•The power demand of the pulse must be below 150% of the nominal output power.
•The duration of the pulse power must be shorter than the allowed BonusPower® time. (see output section)
•The average (R.M.S.) output current must be below the specified continuous output current. If the R.M.S. current is higher, the unit will
respond with a thermal shut-down after a period of time. Use the maximum duty cycle curve (Figure 34 on page 21) to check if the average
output current is below the nominal current.
•The duty cycle must be below 0.75.
