Input Fuse
A fuse mounted inside the converter protects the module in
case of failure against severe defects. The fuse can not be
made externally accessible. Reverse polarity at the input
will cause the fuse to blow.

Input Transient Protection
A metal oxide VDR (Voltage Dependent Resistor) together
with the input fuse and a symmetrical input filter form an ef-
fective protection against high input transient voltages
which typically occur in most installations, but especially in
battery driven mobile applications.
Nominal battery voltages in use are: 24, 36, 48, 60, 72, 96
and 110 V. In most cases each nominal value is specified in
a tolerance of –30%...+25%, with short excursions to
±40% or even more.
In certain applications, surges according to RIA 12 are
specified in addition to those defined in IEC 60571-1 or EN
50155. The power supply must not switch off during these
surges and since their energy can practically not be ab-
sorbed an extremely wide input range is required. The Q
series input range has been designed and tested to meet
most of these requirements. See also:
EMC (surge B).
