Excelsys Technologies Ltd. (Dublin, Ireland) launched a new generation of modular ac-dc power supplies, the Xgen Series, which employ an innovative architecture based on a master ac-dc powerPac and multiple plug-in dc-dc powerMod output modules. The Xgen power supplies are designed specifically for fast user configuration in the development laboratory or field, and are suitable for low-to-medium-volume applications in medical, industrial, data and telecom applications.
The Xgen Series comprises four ac-dc powerPacs, with ratings of 400 W, 700 W, 1,000 W and 1,200 W, and eight plug-in powerMod dc output modules. The range of powerMods covers dc output voltages from 1.5 V to 58 V, and includes single- and dual-output versions, as well as units capable of delivering up to 50 A output current.
Each Xgen ac-dc powerPac measures 260 mm x 127 mm, has a low profile of 40.4 mm, features a universal input that accommodates 85 Vac to 264 Vac (47 Hz to 63 Hz) and 120 Vdc to 380 Vdc, offers a high power density of more than 15 W/in³, and are rated for full power operation over an operating temperature range of -20 °C to +60 °C; (up to +70 °C), with de-rating.
The Xgen Series powerMods use planar magnetics and surface-mount components, which help keep the size down to 80 mm x 36 mm x 12 mm, and employ high-efficiency dc-dc conversion techniques to minimize power losses. The Xgen powerMod provides better than ±0.1% line and ±0.2% load regulation, and the output voltage will deviate by less than 10% for a 25% to 75% step change in load current, and will fully recover in under 250 µs.
The Xgen Series power supplies have a 3,000 Vac input/output isolation rating and carry a full set of international safety approvals, including EN60950 and UL1950. The supplies are also available in medically approved versions, with 4,000 Vac input/output isolation and low leakage current, which meet the EN60601-1 and UL60601-1 standards. Prices for 100-off range from €200, depending on configuration.
