TRACO Power TEP 150UIR and TEP 200UIR DC-DC Converters are offered in 150W or 200W fully encapsulated packages with an ultra-wide 12:1 input range of 14VDC to 160VDC. The TEP 150UIR and TEP 200UIR converters are designed for the highest reliability in demanding applications allowing engineers to target an array of nominal system voltages with a single power supply design. Due to the dedicated holdup capacitor connection, the converters meet extended holdup-time requirements without requiring bulky input capacitors. These converters feature various protections, including short circuit, overvoltage, and overtemperature. TRACO Power TEP 150UIR and TEP 200UIR DC-DC Converters possess many certifications, such as EN 50155 for applications on rolling stock, EN 61373 for mechanical shock and vibration, EN45545-2 for fire behavior, and IEC/EN/UL 62368-1 for IT and general-purpose industrial applications.
