A series of 300W high performance and ruggedised DC/DC converters, featuring ultra-wide 4:1 input voltage ranges and EN 50155 approval for railway applications, has been announced by Power Sources Unlimited. The shock and vibration resistant TEQ 300WIR series is available in single output voltages of 12, 24, 28 and 48VDC. Its chassis mount design is suited for industrial applications where PCB mounting is not possible.

A high efficiency of up to 92% and the overall heat sink construction allows an operating temperature from -40 to +55°C with natural convection cooling without power derating and up to +80°C with power derating. Standard features include output voltage trimming, 3,000VDC I/O isolation, power sharing (up to three units in parallel), soft start, remote on/off and under voltage lockout. The ultra-wide input voltage range, constant current output characteristic and reverse input voltage protection make these converters suitable for battery operated systems.

Pricing starts under $420.00 each in OEM quantities. Prototype quantities are available in 3-4 weeks. PSUI is an ISO 9001:2008 North American authorised distributor for TRACO Power. All TRACO Power products are backed by a three year warranty.
