Output The output provides a SELV/PELV/ES1 rated voltage, which is galvanically
isolated from the input voltage.
The device is designed to supply any kind of load, including capacitive and
inductive loads. If extremely large capacitors are connected to the output, the
unit might charge the capacitor in an intermittent mode. An example of an
extremely large capacitor for use with this power supply is an electric double
layer capacitor (EDLC or “UltraCap”) with a capacitance > 1 F.
The output is electronically protected against overload, no-load, and short-
circuits. If there is a protection event, audible noise may occur.

Fuse-breaking current Typ 60 A Up to 12 ms once every 5 seconds, see Figure 16 on page 12. The fuse-breaking current is an enhanced transient
current that helps to trip fuses on faulty output branches. The output voltage stays above 20V.

Output capacitance Typ 8 500 μF Included inside the power supply
Back-feeding loads Max 35V The unit is resistant and does not show malfunctioning when a load feeds back voltage to the power supply. It does not matter whether the power supply is on or off. The absorbing energy can be calculated according to the
built-in large sized output capacitor.
(1) This current is also available for temperatures up to +70 °C (158 °F) with a duty cycle of 10% and/or not longer than 1 minute every 10 minutes.
(2) At heavy overloads (when output voltage falls below 13V), the power supply delivers continuous output current for 2 s. Next, the output is switched off for approximately 18 s. Next, 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 15 on page 12.

Hold-up Time The hold-up time is the time during which the output voltage of a power supply
remains within specification following the loss of input power. The hold-up
time is output load dependent. At no load, the hold-up time can be up to
several seconds. The green DC OK lamp is also on during this time.

Remote ON/OFF Function This feature is available only for the 1606-XLE480EM and allows to switch-off
the power supply output with a signal switch or transistor. A link between pin
15 and 16 turns on the power supply. Pin 15 is referenced to the (-) output
voltage.
The open-loop voltage between pin 16 and pin 15 can be up to 18V. The
maximum current, when in remote ON mode, can be up to 2.5 mA.
The threshold level to switch-off the output is typically 5V and the turn-on
threshold is typically 9V.
When multiple power supplies are connected in parallel, pin 15 and pin 16 are
also allowed to be paralleled to control all units with the same switch or
transistor.

Lifetime Expectancy The power supply lifetime expectancies in the table indicate the minimum
operating hours (service life). The lifetime expectancies of the built-in
electrolytic capacitors determine the power supply lifetime expectancies.
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 guarantees a maximum life of
up to 15 years (131,400 h). Any number that exceeds 131,400 h 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 figure is a statistical representation of the likelihood of a device to
fail. For example, an MTBF figure of 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.
The Mean Time To Failure (MTTF) of the power supply is the same value as the
MTBF value of the power supply.

Electromagnetic
Compatibility
The electromagnetic compatibility (EMC) behavior of the device is designed
for applications in industrial, residential, commercial, and light industry
environments. The output is allowed to be grounded or floating.
The device is investigated according to EN 61000-6-1, EN 61000-6-2, EN 61000-
6-3, and EN 61000-6-4.
For the power supply to supply a local DC power network in residential,
commercial, and light-industrial environments, it requires additional
measures to reduce the conducted emissions on the output. An example
additional measure is using a filter. No restrictions apply for local DC power
networks in industrial environments.
EMC Immunity Attributes Standards Values Criteria(1)
(1) Criterion A: Device shows normal operation behavior within the defined limits.
Criterion C: Temporary loss of function is possible. The device may shut down. If it shuts down, it restarts by itself. No
