Product Overview The 1606-XLE260F power supply is part of a series of high-end power supplies
in a medium price range that do not compromise quality, reliability, or
performance. The 1606-XLE260F features high efficiency, advanced inrush
current limitation, active power factor correction (PFC), and a wide
operational temperature range.
The 1606-XLE260F includes all essential basic functions of a power supply. It
has a power reserve of 10% up to 60 °C (140 °F) and 20% up to 45 °C (113 °F)
included, even when used continuously. Additionally, the power supply can
deliver three times the nominal output current for at least 12 ms, which helps
to trip fuses on faulty output branches. The power supply has a wide variety of
applications due to its high immunity to transients and power surges, low
electromagnetic emission, DC OK relay contact, and large international
approval package.
Product features include the following:
• AC 100…240V wide-range input
• Width only 39 mm (1.54 in.)
• +10% (5.4 A) continuous current up to 60 °C (140 °F)
• +20% (6 A) continuous current up to 45 °C (113 °F)
• Efficiency up to 95.5%

When using the power supply with a DC input, follow these rules:
• Use a battery or a similar DC source. A supply from the intermediate DC
bus of a frequency converter is not recommended and can cause a
malfunction or damage the unit.
• Connect +pole to L and –pole to N.
• Connect the PE terminal to an earth wire or to the machine ground.

Input Inrush Current An active inrush limitation circuit (NTCs, which are bypassed by a relay
contact) limits the input inrush current after turn-on of the input voltage.
The charging current into EMI suppression capacitors is disregarded in the
first microseconds after switch-on.

(1) Power Boost This power/ current is continuously allowed up to an ambient temperature of 45 °C (113 °F). Above 45 °C (113 °F), do not use this power/
current longer than a duty cycle of 10% and/ or not longer than 1 minute every 10 minutes.
(2) HiccupPLUS Mode At heavy overloads (when output voltage falls below 26V), the power supply delivers continuous output current for 2 s. After this, the
output is switched off for approx 18 s before a new start attempt is automatically performed. This cycle is repeated as long as the overload exists. If the
overload has been cleared, the device operates normally. See Figure 13.
(3) Discharge current of output capacitors is not included.

Lifetime Expectancy The 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 states a
maximum life of up to 15 years (131,400 hr). Any number exceeding this value is
a calculated theoretical lifetime, which can be used to compare devices.
Mean Time Between Failure 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 hr 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 hr or only
for 100 hr.

Terminals and Wiring The terminals are IP20 fingersafe constructed and suitable for field wiring and
factory wiring.
For wiring, follow these rules:
• 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 (158 °F)
• Follow national installation codes and installation regulations.
• Ensure that all strands of a stranded wire enter the terminal connection.
• Unused terminal compartments should be securely tightened.
• Ferrules are allowed.
Daisy Chaining
Daisy chaining (jumping from one power supply output to the next) is allowed
as long as the average output current through one terminal pin does not
exceed 25 A. If the current is higher, use a separate distribution terminal block
as shown in Figure 23.

Safety Features
Attributes Values Notes
Output protection — Electronically protected against overload, no-load, and short-circuits. If there is a
protection event, audible noise may occur.
Output overvoltage protection Typ 58.5V DC If there is an internal power supply defect, a redundant circuit limits the maximum
output voltage. The output shuts down and automatically attempts to restart.
60V DC max
Degree of protection IP 20 EN/IEC 60529
Penetration protection > 4 mm (0.16 in.) Example: screws, small parts
Over-temperature protection Yes
Output shutdown with automatic restart.
The temperature sensor is installed on critical components inside the unit and
turns off the unit in safety-critical situations. For example, when derating
requirements are not observed, there is a high ambient temperature, ventilation is
obstructed, or the mounting orientation derating is not followed. There is no
correlation between the operating temperature and turn-off temperature since
this is dependent on input voltage, load, and installation methods.

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, which 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
cutoff current settings to the value in the following table.
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.
Figure 27 - Dielectric Strength
(1) When testing input to DC OK, ensure that the max voltage between DC OK and the output is not exceeded (column D). We
recommend connecting DC OK pins and the output pins together when performing the test.
