The TEP 150UIR and TEP 200UIR from Traco are series of railway-certified DC/DC converters designed for highest reliability in the most demanding applications. Their ultra-wide 12:1 input voltage ranges allow the application engineer to target an array of nominal system voltages with a single design. Thanks to their dedicated holdup capacitor connections, the TEP 150UIR and TEP 200UIR meet extended holdup-time requirements without the need for bulky input capacitors.
Ultra-wide 12:1 input voltage range: 14–160 VDC
The TEP 150UIR and TEP 200UIR series are EN 50155 certified for applications on rolling stock. Additional certifications include EN 61373 for mechanical shock and vibration, EN 45545-2 for fire behavior and IEC/EN/UL 62368-1 for IT and general-purpose industrial applications. Fully encapsulated, they operate in temperatures from –40°C to +105°C.
