New from ConTech comes the QMS series of DC-DC converters, offering up to 25 Watts of fully regulated output power. The series has a 2:1 input range with nominal input voltages of 12, 24 and 48 V. Single outputs offered are 3,3, 5, 12 and 15 V, while dual outputs are ±12 and ±15 V. The footprint used on the 2,54 x 2,54 cm package is the same as that of an industry standard 2,54 x 5,08 cm, thereby offering a space saving alternative.
The converters operate with efficiencies as high as 90%, with features including remote on/off, output trim and short circuit protection. The operating ambient temperature range is -40°C to +50°C with no derating. The unit is encapsulated with a thermally conductive potting compound in a six-sided metal case for improved thermal performance in still air environments. The QMS series is RoHS compliant.
