Market’s widest XP Power product range

RS COMPONENTS says its new XP Power QSB Series of DC- DC converters means the global multi- channel distributor now has the broadest range of power supplies from XP Power on the market. Designed for applications including signal processing, telecoms, networking and industrial systems, the new QSB Series delivers a stabilised output at a range of standard voltages between 3.3 V and 48 V, at power levels of 75 W to 600 W, says RS.

The QSB Series accepts a wide range of input voltages, typically provided from a battery. Input ranges for most models are 2:1 or 4:1, including 18– 36 or 9– 36 VDC (24 V nominal) and 36–75 or 18–75 VDC (48 V nominal). However, the 150 W QSB15048W models offer a wider 8:1 input range, accepting anything from 9 V to 75 V.

Power conversion efficiency is high: typically between 86 percent and 93 percent depending on model. High power densities of up to 123.0 W/ in3 are achieved. Modules can be connected in parallel for higher power requirements.

All QSB Series power converters provide 1500 VDC isolation, with isolation resistance of 107 Ω or 109 Ω and isolation capacitance ranging from 100 pF to 4000 pF. All provide remote on/off functions, and all except QSB15048W models include remote sense, compensating up to 10 percent of nominal output voltage.

QSB converters are available in baseplate cooled packages with industry standard footprints — including half brick and full brick formats. They can operate over a wide temperature range from – 40°C to +100°C. Over-voltage, over- current and over-temperature protection are provided.

Each unit carries a three-year warranty.
