PULS QS10.241-60 INTRODUCTION
The QS10.241-60 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 -40°C up to +70°C with full output current.
This DC/DC converter comes in a very compact housing and requires only 60mm 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.
