O utput The output provides a SELV/PELV rated voltage, which is galvanically isolated
from the input voltage.
The device is designed to supply any kind of loads, including capacitive and
inductive loads. If large capacitors, such as electric double layer capacitors
(EDLCs) or “UltraCaps” with a capacitance > 0.3 F are connected to the output,
the unit might charge the capacitor in an intermittent mode.
The output is electronically helps protect against overload, no-load, and short-
circuits. If there is a protection event, audible noise occurs
.

(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

(2) At heavy overloads (when output voltage falls below 7V), the power supply delivers continuous output current for 1s. After
this, the output is switched off for approx. 9s 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 will operate normally. See Figure 10.

Fuse breaking
current Typ 30 A Up to 12 ms once every five seconds, see Figure 9. The fuse braking
current is an enhanced transient current which helps to trip fuses on
faulty output branches. The output voltage stays above 10V.

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.

Hold-up Time The hold-up time is the time during which a power supply’s output voltage
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 status indicator is also on during this time
.

Lifetime Expectancy The Lifetime expectancy 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 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.
An MTBF figure such as, 1,000,000 hr means that statistically one unit will fail
every 100 hours if 10,000 units are installed in the field. However, it can not be
determined if the failed unit has been running for 50,000 hr or only
for 100 hr.
For these types of units the MTTF (Mean Time To Failure) value is the same
value as the MTBF value.

In case of an internal defect, a redundant circuit limits the maximum output voltage. The output shuts down and
performs three restart attempts. If the failure continues, the output shuts down. Cycle input power to reset.
Class of protection I According to IEC 61140

Degree of protection IP 20 According to EN/IEC60529
Over-temperature protection Included
Output shut-down with automatic restart. Temperature
sensors are installed on critical components inside the
unit and turn the unit off in safety critical situations,
which can happen for example, when ambient
temperature is too high, ventilation is obstructed or the
de-rating requirements are 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. The
output is insulated to the input by a double or reinforced insulation.
Type and routine 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
cut-off current settings to the value in the table below.
Figure 23 - Dialectic Strength
IMPORTANT Connect either the + pole or the – pole to the protective earth
system. This helps to avoid situations in which a load starts
unexpectedly or can not be switched off when unnoticed earth
faults occur.
