ABSOPULSE Electronics has released the HVT 100R-1K-F2 series, a 100W addition to its line of high input voltage railway DC-DC converters.

The units operate from an input voltage of 900Vdc (525V–1270Vdc range) and deliver 24Vdc, 48Vdc, 110Vdc regulated outputs.

The HVT 100R-1K-F2 units meet the requirements of EN50155 for electronic equipment used on rolling stock and are suitable for a broad range of on-board and trackside applications. The units have heavy filtering on the input and output and comply with EN50121-3-2. They also meet EN61000-4-2, EN61000-4-3, EN61000-4-4 and EN61000-4-6 standards.

The converters are verified for 5600Vdc input to output isolation and production level testing is 3000Vdc input to output, which isolates application equipment from the supply. Other electronic protection includes inrush current limiting, reverse polarity protection, output current limiting, short-circuit protection and self-resetting thermal shut-down in the case of insufficient airflow.

The 100W converters are cooled by conduction via baseplate. Additional cooling is achieved by natural convection through the cooling slots. No fan cooling is required. This enables operation over a -25°C to 55°C temperature range for full specification. Wider temperature ranges are also possible. The units are ruggedised to ensure immunity to shock and vibration. The internal boards are conformal coated for protection from moisture, humidity and airborne contaminants.
