Bel Power Solutions provides leading manufacturers in the railway and transportation industry worldwide with high-performance, rugged DC / DC and AC / DC MELCHER™ brand converters.

With more than 40 years of design and manufacturing experience, MELCHER products are designed to meet the highest national and international standards for harsh environments, safety and electromagnetic compatibility and interference (EMC / EMI) as well as undergo rigorous and extensive engineering and design validation tests ( EVT / DVT), highly accelerated life tests (HALT) and highly accelerated stress screen (HASS) tests.

Our strict engineering guidelines ensure low component stress, thermal profiling and high phase margins for stability and dynamic response.

There are literally hundreds of thousands of Bel Power's MELCHER products installed around the globe, whether on rolling stock or trackside. Our MELCHER cassette DC / DC and AC / DC power converters designed for railway applications have successfully passed all tests and requirements according to the material fire safety of DC / DC and AC / DC converters according to EN 45545-1, EN 45545-2 (2013) for hazard levels HL1 to HL3.

The fire safety tests have been conducted at a certified lab. In addition the above the products also comply with national versions of fire and smoke standards, in particular DIN 5510-2 and NFF 16-101 (1988) classification I3 / F2.

Products features and benefits include:
