High power density supplies are for mission-critical applications

AC/DC power conversion supplies in the NGB series by SL Power have high power density convection for applications including medical, industrial, audio broadcast and LED lighting. They are available in 250, 425, 660 and 1200W (with 150 and 800W being released soon) versions, all with a single output from 12 to 56V DC.

The company has departed from the conventional approach of forced air cooling with fans and instead offers customers increased reliability and eliminates acoustic noise, says SL Power. The focuses on optimising the convection rating performance and the scalable design has customisable options including enhanced digital monitoring and control, multi-output, cardiac float (cf), covers and fan covers.

Whether operating in a medical or industrial environment, the NGB series offers Class I and II inputs with high output stability across wide temperature range up to 50°C without derating, wide universal input voltage range from 80 to 264V AC and high convection power rating (derated only at 90V AC input voltages). The supplies’ lifetime is extended by the use of a seven-year electrolytic capacitor life and they meet Medical 4th Edition and heavy industrial levels of EMC compliance meeting Class B emission levels with margins. The series is approved to CSA / EN / IEC UL62368, IEC61326-1 / UL60601-1, 3rd Edition and carries a three-year warranty.

According to the company, the NGB series offer high reliability and high output current stability over wide variations in operating temperature to ensure reliable performance of mission critical systems in medical, audio and Industry 4.0 applications.

The SL Power product portfolio ranges from a selection of standard, modified, and completely custom turnkey solutions. With more than 60 years of experience in the power industry, SL Power offers OEMs products that are optimised for thermal management, reliability, EMI / EMC, power density, and power efficiency.

SL Power Electronics specifically target three primary market segments: medical, LED, and industrial.
