TRACO POWER TEQ300-7216WIR

DC/DC Converter TEQ 300WIR Series, 300 Watt • High power block with excellent thermal convection • Operating temperature -40°C to +80° • Increased shock & vibration resistance • Ultra wide 4:1 input voltage range • EN 50155 approval for railway applications • Excellent efficiency up to 92% • Constant current output characteristic for battery load applications • Power sharing (up to 3 pcs in parallel) The TEQ-300WIR Series is a family of isolated high performance dc-dc conver- • Input filter meet EN 55032 class A ter modules with ultra-wide 4:1 input voltage ranges which come in a rugged, sealed metal case. • I/O isolation 3000 VDC These converters are suitable for a wide range of applications, but the product is • Infinite capacitive load designed particularly also for industrial applications where often no PCB moun- • Under voltage lock-out circuit ting is possible but the module has to be mounted on a chassis. A very high efficiency and the overall heatsink construction allows an operating temperature • Soft start up to +60°C with natural convection cooling without power derating and up to • Input protection filter +80ºC with power derating. Further features include output voltage trimming, Remote On/Off and under voltage lockout. The ultra wide input voltage range and reverse input voltage protection make these converters also an interesting solution for battery operated systems.
