Absopulse Releases New HVI 109-WR-TX Converter

Absopulse Electronics Ltd. (Carp, Ontario, Canada) released its HVI 109-WR-TX converter, which was designed for use in harsh environments where a wide operating temperature range of –40 °C to +50 °C, and a wide input-voltage range of 400 Vdc to 800 Vdc are required. The rugged unit is suitable for railway, heavy industrial and other adverse environmental applications.

The HVI 109-WR-TX design employs double-conversion topology to generate 24 Vdc continuous voltage at 4 A. It has non-destructive, reverse polarity protection on the input; surge protection; and high-grade input/output filtering to meet EN55022 Class A EMI. The unit is designed to meet international safety approvals, including IEC950, CSA22.2.950 and UL1950. It is conduction cooled and the chassis measures 4.4 in x 2.2 in x 10 in.

The converter can be fully encapsulated to ensure immunity to shock, vibration, humidity, moisture, dust and insects. Optional redundancy diodes would allow for parallel-connection for higher output power or N+1 redundancy, or make it suitable for battery-charging applications.

The standard model HVI 109-WR-TX is priced at $186 in quantities of 25 to 99.
