The HPBC20 of autronic for PCB mounting offers an ultra-wide input voltage range from 14,4 to 154 VDC with 20 W power. A single converter thus covers all international vehicle system voltages for rail vehicles (24 V, 36 V, 72 V and 110 V) including the tolerance range of ± 50155% required by EN 40 in one device. The ultra-wide solution is ideal for Europe-wide operating companies, since a converter is sufficient for the qualification of assemblies.
The EN 50155 in terms of temperature, shock, vibration, as well as the track-specific criteria for EMC, and Surge, Burst and ESD are completely complied with without additional components and make this compact converter (63 x 55 x 20 mm) unique. In addition, the converter has an integrated 10 ms power failure bypass (class S2). The combination of booster and single-ended flow converter in the optimized operating point achieves a high efficiency of approx. 87%.
Overvoltage and overtemperature protection are integrated as standard, and the converter is also idle-proof and permanently short-circuit-proof. In addition to the variant with 5 V output, a variant with 12 V is also planned. Further outputs are available on request.
