Product Overview The 1606 Essential line are cost optimized
power supplies without compromising quality,
reliability, and performance. The most
outstanding features of 1606-XLE240E-3 are
the high-efficiency, electronic inrush-current
limitation, active input-transient filter, and
wide-operational temperature range. The small
size is achieved by a synchronous rectification
and further technological design details.
The 1606-XLE240E-3 is equipped with
conformal coated circuit-boards that are
preferred for applications in harsh areas.
The 1606 Essential line includes all essential
basic functions. The devices have a power
reserve of 20% included, which may even be
used continuously at temperatures up to
45 °C (113 °F). Additionally, the
1606-XLE240E-3 can deliver three times the
nominal output current for 10 ms which helps
to trip fuses on faulty output branches.
The power supply features:
• 3x 380…480V AC wide-range input
• 2 or 3-phase operation possible
• Width only 62 mm (0.039 in.)
• Efficiency up to 92.9% due to synchronous rectifier
• Excellent partial load efficiency
• 20% output power reserves
• Easy fuse tripping due to high overload current
• Input-transient blanking circuit included
• Minimal inrush current surge
• Three input fuses included
• Current sharing feature for parallel use
• Full power between -25 °C...+60 °C (-13 °F...+140 °F)

Installation Notes
• This device may only be installed and put into operation by qualified
personnel.
• This device does not contain serviceable parts. If damage or malfunction
should occur during installation or operation, immediately turn power off
and send unit to the factory for inspection. The tripping of an internal fuse
is caused by an internal defect.
• Install the device in an enclosure providing protection against electrical,
mechanical, and fire hazards.
• Install the device onto a DIN rail according to EN60715 with the input
terminals on the bottom of the device. Other mounting orientations
require a reduction in output current.
• Make sure that the wiring is correct by following all local and national
codes.
• Use appropriate copper cables that are designed for a minimum operating
temperature of:
– 60 °C (140 °F) for ambient temperatures up to 45 °C (113 °F),
– 75 °C (167 °F) for ambient temperatures up to 60 °C (140 °F),
– and 90 °C (194 °F) for ambient temperatures up to 70 °C (158 °F).
• Verify that all strands of a stranded wire enter the terminal connection.
• Unused screw terminals should be securely tightened.
• The device is designed for pollution degree to areas in controlled
environments. No condensation or frost allowed. The enclosure of the
device provides a degree of protection of IP20.
• The isolation of the device is designed to withstand impulse voltages of
overvoltage category 3 according to IEC 60664-1 for corner grounded
delta systems, the overvoltage category level is reduced to level 2.
ATTENTION: Risk of electrical shock, fire, personal injury, or death.
–Do not use the power supply withoutproper grounding (Protective Earth). Use
theterminalon the input blockforearthconnection and not one of the screwson
the housing.
– Turn power off before working on the device. Protect against inadvertent
repowering.
–Do not modify or repair the unit.
–Do not open the unit as high voltages are presentinside.
–Usecaution to prevent any foreign objects from entering into the housing.
–Donotuseinwetlocationsor in areaswheremoistureorcondensationcanbe
expected.
BURN HAZARD: Do not touch while applying power, and immediatelyafter
turning off the power. Hot surfaces may cause burns.
WARNING: Substitution of componentsmay impair suitability for this
environment.
Do not disconnect the device or operate the voltage adjustment unless power
has been switched off or the area is known to be non-hazardous.

Power Supply - 24V, 10 A, 240 W, Three-phase Input
• The device is designed as Class of Protection I equipment according to
IEC 61140.
• Do not use without a proper PE (Protective Earth) connection.
• The device is suitable to be supplied from TN-, TT-, and IT mains
networks. The voltage between the L terminals and the PE terminal must
not exceed 500V AC continuously.
• A disconnecting means shall be provided for the input of the device.
• The device is designed for convection cooling and does not require an
external fan. Do not obstruct airflow and do not cover ventilation grid.

Environment for use above 2000 m (6560 ft).
• Keep the following minimum installation clearances:
– 40 mm (1.57 in.) on top
– 20 mm (0.78 in.) on the bottom
– 5 mm (0.19 in.) left and right side
• Increase the 5 mm (0.19 in.)...15 mm (0.59 in.) in case the adjacent device
is a heat source. When the device is permanently loaded with less than
50%, the 5 mm (0.19 in.) can be reduced to zero.
• The device is designed, tested, and approved for branchcircuits up to 32 A
(IEC) and 30 A (UL) without additional protection device. If an external
fuse is utilized, do not use circuit breakers smaller than 6 A
B- or C-Characteristic to avoid a nuisance tripping of the circuit breaker.
• The maximum surrounding air temperature is 70 °C (158 °F). The
operational temperature is the same as the ambient or surrounding air
temperature and is defined 2 cm (7.87 in.) below the device.
• The device is designed to operate in areas between 5% and 95% relative
humidity.
