20W/40W Dual-Output Railway DC-DCsJune 04, 2019 by Scott McMahan
Traco Power has added products to two series of high-performance railway dc-dc converters. The TEQ 20WIR & 40WIR are two series of isolated railway dc-dc converter modules with 4:1 input voltage ranges. Both series of converters come in a rugged metal case.
These converters are suitable for a broad range of applications, Traco designed them specifically for railway and industrial applications where often no PCB mounting is possible but the module must be mounted on a chassis. Spring clamps also support the converters increased shock and vibration resistance.
Traco extended the product range with additional dual output models (±12Vdc, ±15Vdc, and ±24Vdc) to broaden the variety of typical applications. The new models offer increased shock and vibration resistance.
A very high efficiency of up to 91% and the heatsink construction allow an operating temperature up to +83°C (natural convection) without power derating and up to +93ºC with power derating.
Further features include under-voltage lockout, over-temperature protection and short circuit protection. The converters have EN 50155 approval for railway applications and feature I/O isolation up to 3000Vdc. The input filters the meet EN 55032, class B standard.
Traco backs the dc-dc converters with a 3-year warranty.
