Output Power Derating
The output power of LW models must be decreased at low
input voltage and/or powertrain temperature above 125 °C.
The powertrain temperature depends on the output power, the
input voltage, and the cooling method. At low input voltage the
losses increase. At the maximum specified environment
temperature TA free air convection cooling might be insufficient
approaching maximum ambient conditions. As a result, the
output power has to be reduced according to the tables below.
Input Fuse and Protection
A slow blow fuse ( Schurter T 6.3 A, 5
× 20 mm), protected by a
sleeve, is connected in the line input. EW models have a
smaller fuse (250 V, 4
× 9 mm, SOC NT3 6.3A V009, UL-
recognized E-39265). For DC input voltages above 250 V
observe the Installation Instructions.
Converters with option F have 2 small fuses, one in each input
line. Converters with option E and F have 2 large fuses
( T 6.3 A, 5
× 20 mm). The DC input voltage for all converters
with option F is limited to 250 V.
A VDR and a symmetrical input filter form an effective
protection against input transients.
An under- and overvoltage lockout protects the converter,
which is disabled below Vi min and above Vi max by an internally
generated inhibit signal.
The built-in bridge rectifier provides reverse polarity protection
at the input if operated from DC.
EW models are protected by the (blowing) input fuse in
connection with the body diode of the main transistor. Option Q
offers a serial diode, but this affects efficiency by approx. 1%.
Note: The measurements have been made by the approval
boards with free air convection cooling according to UL 60950
specified ambient temperature TA and with the converter built in a
cardboard box according to UL 508 and a specified temperature
outside the box Tout. The tables give a correlation between TA or
Tout and the case temperature TC (measuring point TC see
Mechanical Data). For models not specified, please contact
Power-One.
EW models have no derating.
