RWY RAIL SERIES DC/DC Converters

Supplier: Helios Power Solutions Pty Ltd

Rugged, DC/DC Converters Deliver up to 280W for Railway and other Harsh Environments. Although developed to meet the stringent requirements for electrical and electronic equipment used on rolling stock, these dc converters are also well suited for use in mining, marine, military and other harsh environments requiring immunity to shock, vibration, dust, humidity and moisture.

The Amtex Electronics RWY 30...280 Series of single & dual output, compact, DC/DC converters are each encapsulated with a thermally conductive MIL-spec. compound, in a 59 x 81 x 56mm enclosure for the RWY30, 65 x 210 x 58 for the RWY200 & 11 x 201 x 61 for the RWY280, and weigh only 650g, 900g & 1.3kg respectively.

The RWY30...280 Series converters deliver between 30W and 280W precision regulated DC outputs from either 72VDC (50-90VDC range) or 110VDC (77-137VDC range) inputs using an advanced switch mode power conversion topology. These units can also be customized for other input and output voltages.

The RWY 30...280 Series meets the requirements of EN50155 (IEC571) Electronic Equipment Used on Rolling Stock Equipment. EMI performance exceeds the requirements for EN55022 Class B with a wide margin for both radiated and conducted measurements.

Combined line-and-load regulation is ±1% from no load to full load. These converters operate within a -40°C to +70°C temperature range without de-rating, with 1.7% de-rating per °C up to 100°C.

They have a proven track record in many major rail and industrial projects in Australia, North America and Europe, and demonstrated MTBF for these units exceeds one million hours at typical operating temperatures.
