Residing in compact metal packages, the 15W JTK15 and 30W JTL30 series dc/dc converters accommodate an ultra wide 4:1 input range. Covering nominal input voltages of 12, 24, or 48 VDC, the units can accept either 9 to 36 Vdc or 18 to 75 Vdc inputs. Measuring 25.4 mm x 25.4 mm x 9.9 mm, the JTK15 series is available in single- or dual-output models while the JTL30 series measuring 50.8 mm x 25.4 mm x 10.16 mm offers single-, dual-, or triple output options. Single output models provide 3.3, 5, 12, or 15 Vdc with the duals providing ±5, ±12, or ±15 Vdc. Triple outputs deliver +3.3 or +5 Vdc with either ±12 or ±15 Vdc combinations. All outputs are fully regulated and vary no more than ±0.5% over all input conditions for single-output models. Dual and triple outputs vary by less than ±1%. Additionally, output voltages are trimmable by ±10% on single-output models. Other shared features include an input to output and input/output to case isolation of 1,600 Vdc for up to one minute, a remote on/off signal, plus over-voltage and continuous short-circuit protection. Prices range from $38.22 for a JTK15 single-output model to $67.08 for JTL30 triple output models in medium quantities. For further information, contact Duane Darrow at XP Power, Sunnyvale, CA.
