San Diego, CA â€šÃ¢â‚¬â€œ TDK-Lambda has unveiled its latest addition to its line of AC-DC medical power supplies. The new single-output CSS65 series, 40 to 65-watt supplies, accept a wide input voltage range, has a very low profile and an industry standard footprint of 2 x 4â€šÃ¢â‚¬Â, with a height of only 1.18â€šÃ¢â‚¬Â, making it an ideal choice for applications in medical equipment, gaming, point-of-sale and test & measurement equipment, to name a few.
These new open-frame supplies feature a universal 90-264Vac, 47-63Hz input, enabling them to be used anywhere in the world, plus they can operate from a 120-300Vdc input. Fuses are mounted internally on both the Line and Neutral inputs (dual fuses). These supplies feature a very low leakage current of less than 250â€šÃ‚ÂµA at 264Vac, 63Hz, which is most important for medical applications. In addition, the CSS65 is designed to withstand 4kVac, input-to-output. The series are available with an output voltage of 5V, 12V, 15V, 19V, 24V, 36V or 48V, and can operate with convection cooling (no fans required). The operating temperature range is from -10â€šÃ‚Â°C to +70â€šÃ‚Â°C with derating above 50â€šÃ‚Â°C. The outputs are floating so they can be used as either a positive or negative polarity.
Remote sense connections are provided to compensate for cable drops between the output terminals and the load. Other standard features include overvoltage and short-circuit protections. The input and output connections mate with standard Molex connectors. The CSS65 series have global medical safety agency approvals per UL/EN/IEC60601-1; meet the conducted and radiated EMC requirements of EN55022-B and FCC Class B, which is much tougher to meet than Class A and are RoHS compliant.
