Product description

DC/DC converter AER-Serie, compact power supply for the railway applications

The Autronic AER series are a generations of high performance, convection cooled DC/DC converters from 3 W to 75 W. The AERs have been designed specifically for use in railway applications and in harsh environments. Due to their compact design the small power supplies can perfectly be used in display solutions, customer information systems, radio modules or for switches and repeaters. Additionally, due to their UL/cUL60950 certification they are a safe choice for industrial and telecommunication applications.

The electrically isolated power supplies are available with an input of 4:1, 11:1 or 18:1, which covers the input range of 12 to 110 VDC, including a tolerance of +/- 40%. The compact module solutions comply with the railway standard EN 50155 as well as the EMC standard EN 50121-3-2 with low external components.

The DC/DC converters certified for railway applications have a very high efficiency in a compact housing and can be used for operating temperatures between -40°C and 85°C (case up to 100 °C). Optionally, the power supplies are available with heat sink, so higher heat dissipation can be guaranteed even at higher requirements. Other product features are the high insulation (I/O 3000 Vdc), remote on/off, undervoltage shutdown, overload and over-temperature protection which provides protection against damages.

The DC/DC converters are available with single output with 5V, 12V, 15V, 24V and 48V and dual output with +- 12 V and +-15 V. The outputs can be trimmed. No minimum load is required; the start time of the converter is very fast.

The bricks have been tested according to the Fire and Smoke EN 45545-2, and have passed the shock/vibration test according to EN 61373 (category 1, class B). Acceptance according to EN 60950-1/62368-1 is available.
