Offering a wide 4:1 input range, both series have 9-36 VDC or 18-75 VDC inputs that cover the nominal input voltages of 12, 24 or 48 VDC. Comprising of single and dual output variants, there are a total of 28 models across the two series. Single output models offer 3.3, 5, 12 or 15 VDC while dual output voltages are +/- 5, +/- 12 or +/- 15 VDC. Output voltages are fully regulated to within +/- 0.5% over all input ranges and to less than +/- 1.0% across all load conditions. Both devices feature an input to output and input/output to case isolation of 1,600 VDC for up to 1 minute.
With a maximum case temperature of +105 degrees C, the units can operate at full output power from -40 degrees C to +60 degrees C without derating. No additional heat sinking or forced airflow is required making the converters suitable for most operating environments.
These highly reliable DC/DC converters comply with MIL-STD-217F for predicted lifetime. The JTF12 has a MTBF in excess of 1 million hours and the JTM20 is rated at 560 thousand hours.
A remote on/off signal is included as standard, allowing engineers to design-in the ability to sequence converter start-up or control the outputs.
The JTF12 and JTM20 products are available now from Farnell or direct from XP Power.
