300W single output power supply from TDK-Lambda
Posted : 03 Jun 2010
Complementing its popular SWS range of power supplies, TDK-Lambda has developed the SWS300A series of single output units. Low cost and low profile, yet boasting advanced features such as active power factor correction and high input transient protection, these 300W general purpose power supplies operate from a universal input of 85 to 265VAC or 120-370VDC to meet a wide range of applications, including factory automation, test & measurement and display signs.
Offered with a choice of output voltages from 3.3V to 48V, each model in the SWS300A series can be adjusted by up to ±20% of its nominal voltage to accommodate non-standard system voltages. Furthermore, all power supply models incorporate an internal cooling fan for reliable power output over a wide temperature range of -10°C to +65°C. Over voltage, over current and over temperature protections are standard features; with a green power-on LED, the unit is switched on.
With input transient protection that meets IEC61000-4, the SWS300A models have a 3kVAC input to output isolation with Class B conducted and radiated EMI performance. The TDK-Lambda SWS300A series of single output, general purpose power supplies is approved to a wide range of safety standards, including ICE/UL/CSA/EN60950-1 and EN50178, and all models carry the CE mark, according to the LV Directive. All models carry a two-year warranty.
