New power supplies offer superior performance and reliability

26-11-2021 | SL Power | Power

SL Power Electronics has launched the NGB Series of high-power density convection rated AC/DC power supplies. Designed for applications including industrial, medical, audio broadcast and LED lighting, the series provides a wealth of application relevant features and is offered in multiple formats and power levels, including 250W, 425W, 660W and 1200W (with 150W and 800W coming soon), all with a single output from 12–56VDC.


Departing from the commonly used industry approach of optimising a design to need forced air cooling with fans, the series provides customers increased reliability and excludes acoustic noise. Its next-generation design optimises the convection rating performance. It uses a scalable design strategy with highly customisable options, incorporating enhanced digital monitoring and control, multi-output, cardiac float, covers and fan covers.


Whether operating in an industrial or medical environment, the series provides Class I and II inputs with high output stability over wide temperature range up to 50C with no derating, wide universal input voltage range from 80-264VAC, high convection power rating (derated only at 90VAC input voltages), lifetime extended by the use of greater than seven-year electrolytic capacitor life, Medical 4th Ed. and heavy industrial levels of EMC compliance meeting Class B emission levels with margins, approved to CSA/EN/IEC UL62368, IEC61326-1/UL60601-1, 3rd Edition and three-year warranty.


Gary Baker, UK country manager for SL Power, comments: "By designing our new NGB series power supplies from the ground up, we are able to meet the needs of today’s systems designers looking for high reliability and high output current stability over wide variations in operating temperature, which ensures the reliable performance of mission critical systems in medical, audio and Industry 4.0 applications.”
