DC/DC Converter TEP 40UIR Series, 40 Watt Ultra-wide 12:1 input voltage range 975, 14160 VDC Compact 2.3x1.45x0.5 standard package (quarter brick) Bus pin to easily extend hold-up time EN 50155 and EN 61373 approval for railway applications Qualification for fire behavior according to EN 45545-2 Operating temperature range 40C to +85C UL 62368-1 IEC 62368-1 I/O-isolation 3000 VAC The TEP 40UIR is a series of high performance 40 Watt railway DC/DC convert- ers with ultra wide 12:1 input voltage range featuring a compact brick High efficiency up to 91% (2.3x1.45x0.5) metal package. The ultra wide input allows the converter to Adjustable output voltage, Remote act as an all-in-one solution if different voltage ranges have to be covered in the On/Off and adjustable under voltage same application, resolving the issue of having multiple different converters in- lockout stalled. 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 ca- 3 year product warranty pacitors 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 +85C and an I/O-isolation voltage of 3000 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.
