Standards and Approvals
The converters are UL recognized according to UL 1950, for
Canada to CAN/CSA C22.2 No. 950-95, and TüV approved to
IEC/EN 60950 standards.
The converters correspond to Class I equipment and have been
evaluated for:
Building in,
Basic insulation between input and case based on 250 V and
double or reinforced insulation or an earthed part between input
and output.
The use in a pollution degree 2 environment,
Connecting the input to a primary or secondary circuit which is
subject to a maximum transient rating of 2500 V.
The converters are subject to manufacturing surveillance in
accordance with the above mentioned UL and ISO 9001:2000
standards.
Railway Applications
The K Series converters have been designed according to the
Railway Standards EN50155 and EN50121. All boards and
components are coated with a protective lacquer.
Cleaning Agents
In order to avoid possible damage, any penetration of cleaning
fluids must be prevented, since the power supplies are not
hermetically sealed.
Protection Degree
Condition: Female connector fitted to the converter.
IP 30:
All models except those with option P and option D,
or V with potentiometer.
IP 20:
All models exhibiting a potentiometer.
Important:
When the inhibit function is not in use, pin no. 18 (i) should
be connected to pin no. 14 (S–/Vo1–) to enable the output(s). Do not
open the converters, or guarantee will be invalidated.
Due to high current values, some models provide two internally
parallel connected contacts for certain paths (pins 4/6, 8/10,
26/28 and 30/32). It is recommended to connect load and
supply to both female connector pins of each path in order to
keep the voltage drop across the connector pins at an absolute
minimum and to avoid overstress of the connector contacts with
currents higher than 8 A.
Make sure that there is sufficient air flow possible for convection
cooling. This should be verified by measuring the case
temperature when the converter is installed and operated in the
end-use application. The maximum specified case temperature
T
Cmaxshall not be exceeded. See also
Thermal Consid-
erations.
If the end-product is to be UL certified, the temperature of the
main isolation transformer should be evaluated as part of the
end-product investigation.
Check for hazardous voltages before altering any connections.
Ensure that a converter failure (e.g., by an internal short-circuit)
does not result in a hazardous condition. See also:
Safety of
Operator Accessible Output Circuits.
Isolation
The electric strength test is performed in the factory as routine
test in accordance with EN 50116, IEC/EN 60950 and UL 1950
and should not be repeated in the field. Power-One will not
honor any guarantee claims resulting from electric strength field
tests.
LK-models Operated at Greater than 63 Hz
Above 63 Hz the earth leakage current may exceed 3.5 mA, the
maximum specified in IEC/EN 60950. The built-in Y-caps are
only approved for
≤
100 Hz. Frequencies greater than 350 Hz
are only permitted for
