Rugged DC/DC Converter with 400VDC to 800VDC Input Range Operates in -40ºC to +50ºC Environments
03 December 2004
Absopulse Electronics’ HVI 109-WR-XT converter was designed for use in harsh environments where a wide operating temperature range of –40ºC to +50ºC and a wide input voltage range of 400VDC to 800VDC are required. This rugged unit is ideally suited to railway, heavy industrial as well as other applications in adverse environments.
The HVI 109-WR-XT design employs field-proven, double-conversion topology to generate 24VDC continuous voltage at 4A. It has non-destructive reverse polarity protection on the input, surge protection and high-grade input/output filtering to meet EN55022 Class A EMI as a minimum. The unit is designed to meet international safety approvals including IEC950, CSA22.2.950 and UL508. It is conduction cooled and the chassis measures 4.4in x 2.2in x 10in.
This 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.
Absopulse’s HVI (high voltage input) Series incorporates an extensive range of high input voltage converters with output power ranging from 50W to over 3,000W.
