Autronic has redefined a true classic with the updated HFBC60-W/Ks. Under the motto "Familiar on the outside, completely new on the inside," the compact and powerful converter has undergone extensive modernization to continue meeting the demanding requirements of railway technology. The HFBC60-W/Ks complies with the stringent standards EN 50155 and EN 50121-3-2, making it ideal for use in harsh environments along the railway too.
The HFBC60-W/Ks’s compact dimensions (113 mm x 46 mm x 35 mm) enable seamless design-in. Its full compliance with railway-specific EMC requirements (surge, burst, emissions, and immunity) eliminates the need for additional circuitry. An integrated 10-ms hold-up time ensures reliable operation even during short-term voltage dips. The converter impresses with features such as active inrush current limitation, active reverse polarity protection, and comprehensive safeguards against overcurrent, overvoltage, and overheating (OVP, OCP, OTP). Customers have long appreciated how easy this converter is to put into operation.
Flexibility and Efficiency
With just one converter, nominal input voltages from 24 V to 110 V (±40%) are covered, significantly simplifying the approval process for customer applications. The galvanically isolated converter guarantees reliable performance with an efficiency of up to 91 % and an output power of 60 W, providing full operating security without derating—even under extreme temperature conditions (OT4, ST1, ST2) or all permissible input voltage ranges.
Installation is remarkably simple: natural convection combined with contact to the mounting surface is entirely sufficient. The materials chosen for the PCB and potting compound meet the highest fire safety standards in accordance with EN 45545-2 (HL3). The HFBC60-W/Ks is available with output voltages of 5 V, 12 V, and 24 V, seamlessly integrating into any design. Versions with a power output of 100 W are also available.
