The New range of HAE150U and HAE200U DC/DC Power Converters are suitable for the harsh mechanical and electrical environment of traction vehicles and rolling stock applications. It has an ultra-wide input voltage range from 16V to 160V and covers all the input power systems of railway applications which are 24V, 28V, 36V, 48V, 72V, 96V, 110VDC. Ultra-wide input voltage converters usage has risen lately, due to the increase of onboard electronic systems such as video surveillance, access and ticketing machines, passenger device-charging USB ports, infotainment, information systems and telemetry.
According to EN50155 standard (defines the supply requirements for electronic equipment in rail applications), equipment powered directly from batteries with no voltage stabilizing device must function properly with input voltages that range from 0.7VN to 1.25VN during normal operation. The equipment must also withstand input voltage drops of 0.6(VN) for 100 ms and overvoltage surges of 1.4VN for one second that may occur during startup. The HAE150U & HAE200U Series with its input voltage range from 16V -160V or 12VDC in transient operation meets stringent railway sector performance standards.
Up to 93% high efficiency means a reduced requirement for cooling, and their remote on/off facility enables simple, reduced power consumption in the off condition. Plus, it reduces the capacitance of hold-up capacitors by applying the enhanced hold-up function to meet the requirements of supply interruption and change-over.
HAE150U and HAE200U feature full protections, such as: over current protection, short circuit protection, output over-voltage protection, input under-voltage lockout, over-temperature protection, etc. HAE150U and HAE200U meet IEC 62368-1, EN 50155, and EN 45545-2 for ITE and railway applications.
