The TEQ 20WIR & 40WIR are two series’ of isolated high performance railway DC/DC-converter modules, with 4:1 input voltage ranges arranged in a rugged metal case. These converters are suitable for a wide range of applications, but they prove especially effective within railway and industrial applications, where one can struggle to organise PCB mounting, while the module is mounted on a chassis. Spring clamps additionally support the converters’ increased shock & vibration resistance.  

The product range is now extended, with additional dual output models (±12, ±15 & ±24 VDC) to further increase the application’s range. A very high efficiency and heatsink construction allows for an operating temperature of up to +83 degrees Celsius (natural convection), without power derating and up to +93 degrees Celsius with power derating. Further features include under voltage lockout, over temperature protection and short circuit protection.
