Summary
Innovative design and attention to detail make the LW se-
ries the choice of many design engineers. These compact
power supplies feature a total volume of nearly three times
less than conventional switchers in the same power range.
MOSFET switching technology and component derating
further assure high reliability. The LW's flex power output
design easily accommodates changing design needs and
power requirements. Universal AC input is standard on all
15 and 30 W rated triple output models. Safety approvals
according to UL 1950, CSA 950 (EB 1420C) and IEC/EN
60950.
Key applications
Equipment for office automation, factory automation, pe-
ripheral, communication, security, display, test and meas-
urement, inspection and medical.

Proper Method of Operation
Inrush Current
To achieve the proper output voltage from each of the three
outputs, the individual load currents must remain within the
minimum-maximum ratings. If the load current can drop be-
low the minimum value specified, add a pre-load.
All models feature inrush current limitation circuits by
means of power thermistors. Switching the AC input on/off
repeatedly in rapid succession (less than 2 minutes waiting
time) should be avoided. An appropriate AC switch for each
model based on its specifications should be provided.
Output Current Limitation
Series or Parallel Connection
Each output provides its own built-in current limitation at
approx. 105% of the rated currents. In case of overload, the
circuit limits the current. After removal of overload, the cir-
cuit automatically resets.
The outputs cannot be operated in series or parallel con-
nection with other type of sources.

Po/Po max
The relation between the maximum allowed output power
Po allwed, the temperature TA of the surrounding air and the
mounting method is given in the: Installation Instruction.
The percentage rates apply if the AC-DC converter is lo-
cated in free, quasi-stationary air (convection cooling).

The following figure shows the allowed output power of an
AC-DC converter if mounting method A is used.
For Po max values see: Type Survey and Key Data. The ther-

rent, airflow and temperature of surrounding components
and surface.

Electromagnetic Compatibility (EMC)
Electromagnetic Immunity
A metal oxide VDR together with an input fuse and an input
filter form an effective protection against high input tran-
sient voltages which typically occur in most installations,
but especially in battery driven mobile applications. The
VEW series has been successfully tested to the following
specifications:

Safety and Installation Instructions
Installation Instructions
Our AC-DC converters are components, intended exclu-
sively for inclusion within other equipment by an industrial
assembly operation or by professional installers. Installation
must strictly follow the national safety regulations in compli-
ance with the enclosure, mounting, creepage, clearance,
casualty, markings and segregation requirements of the
end-use application. See also: Technical Information: In-
stallation and Application.
in the wiring to the phase terminal L. A second fuse in the
wiring to the neutral terminal N is needed if:
• Local requirements demand an individual fuse in each
source line
• Neutral and earth impedance is high or undefined
• Phase and neutral of the mains are not defined or cannot
be assigned to the corresponding terminals (L to phase
and N to neutral)
Connection to the system shall be made via the terminal
block at the rear side of the unit according to: Terminal As-
signment.
Important: Do not open the modules, or guarantee will
be invalidated.
Make sure that there is sufficient air flow possible for con-
vection cooling. This should be verified by measuring the
ambient temperature when the unit is installed and oper-
ated in the end-use application. The maximum specified
ambient temperature TA max must not not be overriden, de-
pending on output power and mounting method. See: Ther-
mal Considerations and table: Allowed output power by
mounting method.
For safety reasons it is essential to connect the FG and
ACG terminals with protective earth. See also: Safety of op-
erator accessible output circuit.
A fuse is built-in in the connection from the L terminal of the
unit. Since this fuse is designed to protect the unit in case of
an overcurrent and does not necessarily cover all customer
needs, an external fuse suitable for the application and in
compliance with the local requirements should be installed

The AC-DC converters correspond to class I equipment
and are UL recognized according to UL 1950, UL recog-

The electric strength test is performed as factory test in ac-
cordance with IEC/EN 60950 and UL 1950 and should not
be repeated in the field. Melcher will not honour any guar-
antee claims resulting from electric strength field tests.

Safety of operator accessible output circuit
If the output circuit of an AC-DC converter is operator ac-
cessible, it shall be an SELV circuit according to the IEC/EN
60950 related safety standards
60950 up to a configured output voltage (sum of nominal
voltages if in series or +/– configuration) of 44 V.
However, it is the sole responsibility of the installer to as-
sure the compliance with the relevant and applicable safety
regulations. More information is given in: Technical Infor-
mation: Safety.
The following table shows a possible installation configura-
tion, compliance with which causes the output circuit of the
AC-DC converter to be an SELV circuit according to IEC/EN
