40 and 60W railway DC-DC converter series with 12:1 inputs
Traco Power has launched two series of DC-DC converter with railway approvals and a wide 12:1 input range
The TEP 40UIR & TEP 60UIR railway DC-DC converter series are housed in a compact quarter brick (2.3”x1.45”x0.5”) metal package.
The ultra wide input of 9–75 and14–160 VDC allows the converter to act as an all-in-one solution if different voltage ranges have to be covered in the same application, resolving the issue of having multiple different converters installed. An internal circuit implemented in these modules helps to extend the hold-up time with ease as it eliminates the need of expensive high voltage capacitors to cover the full input range. With only a 25V capacitor (independent of the input voltage) the whole input range can be covered effectively reducing cost, size an inrush current.
All models are approved for railway applications according to EN 50155, EN 61373, EN 45545-2 and offer standard features such as high efficiency up to 91%, an operating temperature range of -40° to +85°C and an I/O-isolation voltage of 3,000 VAC. An adjustable under voltage lockout function, remote on/off and adjustable outputs round out the features and ensure that these converter modules fit in any application setup.
