TDK-Lambda LS Series single-output, power supplies increase to 200W

Posted : 20 Oct 2010

Leading power supply manufacturer TDK-Lambda UK adds a 200W model to its successful single output LS series of general purpose power supplies, with models now covering from 25W up to 200W. While the LS200 is particularly well-suited to budget conscious applications, it carries more functions than similarly priced products available on the market today and can fit into a 1U rack.

The LS200 has a universal input range of 85 to 264Vac (47-63Hz) with PFC meeting EN61000-3-2, 3, and can withstand a 300Vac surge for five seconds. Over current with constant current limiting, over voltage and over temperature protection circuitry are standard features of the LS200, as well as remote on/off signal, green LED ‘ON’ indicator and remote sensing. Available either enclosed with low noise fan or U-channel style with convection or customer airflow cooling, the efficient design of the LS200 achieves excellent thermal balance and 299K hours MTBF – up to 63% longer than competitor examples.

Nominal output voltages range from 3.3 to 48Vdc, delivering currents of up to 40A. To accommodate non-standard system voltages, the LS200 is user adjustable by up to -10/+20% (for 12V, 24V & 48V). Offered with an extended -25 to +70°C operating temperature range, the LS200 thermal design enables full power output up to 50°C and 60% output power at 70°C. Furthermore, the 24V and 36V output voltage models have 250W peak power capability.

As well as meeting EN55011/EN55022 class B conducted and radiated emissions, LS200 meets UL/IEC 60950-1 edition 2 safety approvals and carries the CE mark. The LS200 series comes with a three-year warranty. Size is 199 x 98 x 41mm.
