Half Bricks with 16.8- to 137.5-Vdc Inputs Target Rolling Stock

Delta Electronics, Inc. has introduced the H80SV series for rail transportation applications, a family of standard half brick isolated dc-dc converters with extreme wide input voltage range. The converters are constructed according to EN 50155 to ensure harsh environmental operations.

With extremely wide input voltage range (16.8- to 137.5-Vdc continuous, 14.4- to 200-Vdc transient), multiple standard output voltage (12Vdc, 15Vdc, 24Vdc, 48Vdc and 54Vdc) and output power (100W and 200W) selection, H80SV series is suitable for a variety of electronic system in locomotive and high-speed trains.

The high power conversion efficiency (91.5% @72Vin, 15Vout, 200W) allows the power module operate at extreme thermal environments, and the operating temperature range of the converters is -40°C to +100°C.

The H80SV series comes with a host of industry-standard features, such as over-voltage protection, over-current protection, over-temperature protection and input UVLO protection. The series is constructed according to EN50155 to ensure harsh environmental conditions do not influence its mode of operation. The H80SV series meets UL60950-1 & 62368-1 safety standard and fire & smoke meets EN45545-2.
