Leading power supply manufacturer Lambda has upgraded its SWS series of single output AC/DC power supplies. Already recognised as offering high reliability and performance in cost-sensitive applications, the new SWS models offer higher power output and an increased voltage output range.

Lambda is introducing three new SWS300 models: the SWS300-5, SWS300-24 and SWS300-48, with the final figures referring to the output voltage. Maximum output power on the SWS300-5 is 275W, rising to 321.6W on the SWS300-48. Lambda is also introducing three SWS600 models designed for higher current and power output applications. The SWS600-5 has an output power of 500W with 600W peak, while the SWS600-24 & -48 are both capable of 600W continuously.

Each model accepts a continuous input from 85 to 265V which means they are compatible with global standards. Lambda has incorporated soft-start circuitry, an integral Class B EMI filter and over voltage and current protection. The series is CE marked and carries UL, CSA, EN60950 and EN50178 safety approvals.
Operating temperature range is –10 to 65ºC, with a temperature coefficient of less than 0.02%/ºC. The dimensions of the SWS300 series are 52x102x198mm and 92x120x190mm for the SWS600 series.
