K Series with PFC Data Sheet
150 – 280 Watt AC-DC Converters
An additional external fuse, suitable for the application,
might be necessary in the wiring to the other line input 26 /
28 (N~) if:
? Local requirements demand an individual fuse in each
source line
? Phase and neutral of the mains are not defined or
cannot be assigned to the corresponding terminals (L~
to phase and N~ to neutral).
? Neutral and earth impedance is high or undefined
Notes:
– If the inhibit function is not used, pin no. 18 (i) should be
connected to pin no. 14 (S–/Vo1–) to enable the output(s).
– Do not open the converters, or warranty will be invalidated.
– Due to high current values, the converters provide two
internally parallel contacts for certain paths (pins 4/6, 8/10,
26/28 and 30/32). It is recommended to use both female
contacts in parallel connection order to keep the voltage
drop and the temperature of the contacts low.
– If the second output of double-output models is not used,
connect it in parallel with the main output.
Make sure that there is sufficient airflow available for
convection cooling. This should be verified by measuring
the case temperature, when the converter is installed and
operated in the end-use application; see Thermal
Considerations.
Ensure that a converter failure (e.g., an internal short-
circuit) does not result in a hazardous condition; see also
? Overvoltage category II
? Pollution degree 2 environment
? Max. altitude: 2000 m.
? The converters fulfill the requirements of a fire enclosure.
All boards of the converters are coated with a protective
lacquer.
The converters are subject to manufacturing surveillance
in accordance with the above mentioned UL standards
and ISO 9001:2000. A CB-scheme is available.
Cleaning Agents
In order to avoid possible damage, any penetration of
cleaning fluids is to 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 except
those with option D or V including a potentiometer.
? IP 20: All models fitted with option P, or with option D or
V with potentiometer.
Leakage Currents
Leakage currents flow due to internal leakage capacitances
and Y-capacitors. The current values are proportional to the
supply voltage and are specified in the table below.

The converters correspond to Class I equip-
ment and have been evaluated for:
? Building-in
? Basic insulation between input and case based on 250
VAC, and double or reinforced insulation between input
and output(s).
? Functional insulation between outputs.

The electric strength test is performed in the factory as
routine test in accordance with EN 50116 and IEC/EN
60950 and should not be repeated in the field. Power-One
will not honor any warranty claims resulting from electric
strength field tests.
