K Series with PFC Data Sheet
150 – 280 Watt AC-DC Converters
Installation Instructions
Note: These converters have a power factor correction (PFC).
The LK4000/5000 models are intended to replace the LK1000
and LK2000 converters in order to comply with IEC/EN 61000-
3-2. LK1000 is replaced by LK4003 with option K.
Switch off the system and check for hazardous voltages
before altering any connection!
These converters are components, intended exclusively
for inclusion within other equipment by an industrial
assembly
operation
or
by
professional
installers.
Installation
must
strictly
follow
the
national
safety
regulations in compliance with the enclosure, mounting,
creepage, clearance, casualty, markings, and segregation
requirements of the end-use application.
Connection to the system shall be made via the female
connector H15 (standard) or H15S2; see: Accessories.
Other installation methods may not meet the safety
requirements.
Pin no. 24 ( ) is reliably connected with the case. For
safety reasons it is essential to connect this pin reliably to
protective earth. See: Safety of Operator-Accessible
Output Circuits.
The phase input 30/32 (L~) is connected via a built-in fuse
(see: Input Fuse and table 4), which is designed to protect
in the case of a converter failure.
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 connect load
and supply to both female connector pins of each path in
order to keep the voltage drop low and to not
overstress the connector contacts with high
currents.
– If the second output of double-output models is not
used, connect it 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:
Safety of Operator-Accessible Output Circuit.
Standards and Approvals
The converters are approved according to UL 60950-1,
CSA 60950-1, IEC 60950-1, and EN 60950-1.
The converters correspond to Class I equipment 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).
Basic insulation between output(s) and case based on
200 VAC.
Functional insulation between outputs.
Overvoltage category II
Pollution degree 2 environment
Max. altitude: 2000 m.
The converters fulfill the requirements of a fire enclosure.
CB-scheme is available: SI-1819 (IEC 60950-1:2001)
All boards and components 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.
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 unit.
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.
Isolation
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
