TDK-Lambda PYH200 200W Single-Output DC-DC Converters are board-mount 200W DC-DC converters in a rugged half-brick housing with silicone potting. The TDK-Lambda PYH200 DC-DC Converters provide a regulated and galvanically isolated output voltage. The series boasts a 14V to 160V (12:1) input voltage range and 3000VAC input/output (I/O) isolation strength. These DC-DC converters feature a -40°C to +100°C case temperature range and low heat generation due to the high efficiencies of up to 90%. These features and the high shock and vibration resistance (thanks to the potted design) make this device suitable for nearly every situation. PYH200 complies with EN 50155 international standard, covering electronic equipment used on rolling stock for railway applications.
