The output power of this product isThe 250 watt converter provides an input range of 14.4 volts to 154 volts in one device.

AUTRONIC has added HFBC250-2DW to its railway DC/DC converter series with wide input. This converter with an output power of 250 watts covers an input range of 14.4 volts to 154 volts through a single device. All requirements for the use of railway technology are met with a small footprint and flat design.

Efficiency of plug and play solutions91% to 95%, convenient for design in customer applications. High efficiency performance has been achieved across the entire temperature range within the allowed input voltage range.

No additional filtering by external components is required to meet the requirements of railwaysEMC requirements (surge, emission, immunity, etc.). Other functions include active surge current limiting (30A), active reverse polarity protection, and overcurrent, overvoltage, and overheat protection (OVP, OCP, OTP). The integrated 10ms hold time helps applications in the event of short-term power failures.

Due to the fact that all European input voltages are converted by a single converter, this simplifies the design and thus simplifies the approval process for customer applications. Electrical insulationHFC250-2DW is developed based on temperatures OT4, ST1, and ST2, and can operate at 250 W, reaching up to 70 ° C and 85 ° C for at least 10 minutes. In addition to natural convection, the simple installation of Autronic converters only requires contact with the lower side to dissipate the generated heat to the housing, thus eliminating the need for complex heat sinks. The selection of circuit board materials is based on fire testing.
