PULS QS5.241-60 INTRODUCTION
The QS5.241-60 DC/DC converter is designed specifically
for railway & transportation applications. It is approved
according to the EN 50155 standard, which is an
international standard covering electronic equipment
used on rolling stock for railway applications. The
standard covers aspects such as temperature, humidity,
shock, vibration, EMI, and other parameters. Because of
these requirements, the unit is equipped with
conformal-coated PC boards. The unit features a DC-OK signal contact for remote
monitoring and quick-connect spring-clamp terminals
for a reliable connection even when mechanical
vibration and shock are involved.
The unit also covers an
extremely wide temperature range from -25°C up to
+70°C with full output current.
This DC/DC converter comes in a very compact housing
and requires only 40mm of space on the DIN rail due to
its high efficiency and low power losses. The high
efficiency is achieved by utilizing cutting-edge
technology and other unique design techniques.
