Lambda’s new LS Series of convection cooled single output power supplies is available in 50, 75, 100 and 150W models. These general purpose units from Lambda are well-suited to budget conscious applications, but feature an extremely efficient design that achieves excellent thermal properties and offers high reliability.
The LS50, LS75 and LS100 are 88 to 264Vac input, while the LS150 models are switch selectable for 115 or 230Vac thus minimising cost. All LS units withstand a 300Vac surge for five seconds minimum.
Standard output voltages range from 3.3 to 48Vdc, delivering currents up to 30A. To accommodate non-standard system voltages, the LS Series is user adjustable by ±10%. Models within the LS Series are up to 4% more efficient than similar products available on the market. The 50W LS50-24 model, for instance, achieves a typical efficiency of 86%.
Offered with an extended operating temperature range, the LS Series provides full power from -25 to +50°C and can still deliver up to 70% power at 70°C depending on the chosen model. Overcurrent and overvoltage protection are standard features, as is a power on signal.
As well as being EN55011/EN55022 and FCC compliant (achieving class B conducted and radiated emissions), Lambda’s new series meets UL/EN/IEC 60950-1 safety approvals and carries the CE mark. All models meet EN61000-3-2, 3 harmonic correction standards. With a MTBF of over 600k hours, per MIL-HDBK-217F (25°C) standard, Lambda’s LS Series comes with a three-year warranty.
