It employs soft-start circuitry, has an integral Class B EMI filter and provides over voltage and over current protection. Other features include an output adjustment potentiometer (+/- 10%), integral power good LED indicator and screw terminals for input and output connections.

Four models are available with nominal output power ratings of 50, 75, 100 and 150W. Each model can be supplied with a choice of 5, 12 or 24V output. The company will extend the SWS series soon to offer more output voltage selections between 3 and 48V.

CE marked in accordance with the Low Voltage Directive, the new SWS series carries UL, CSA, EN60950 and EN50178 safety approvals. All models conform to EN61000-3-2, the SWS100 and SWS150 being fitted with an integral active PFC filter. Other approvals include EN55011-B, EN55022-B, FCC-B, and EN61000-4.
