TDK-Lambda has added a 200 W model to its single-output LS series of general purpose power supplies, with models now covering from 25 W up to 200 W. The LS200 is targeted at budget conscious applications and can fit into a 1U rack.
The power supply has a universal input range of 85 to 264 V a.c. (47-63 Hz) with PFC meeting EN61000-3-2, 3, and can withstand a 300 V a.c. surge for five seconds. Over-current with constant current limiting, over-voltage and over-temperature protection circuitry are standard features, 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 299 000 hours MTBF.
Nominal output voltages range from 3,3 to 48 V d.c., delivering currents of up to 40 A. To accommodate non-standard system voltages, the LS200 is user adjustable by up to -10/+20% (for 12 V, 24 V and 48 V). Offered with an extended -25°C to +70°C operating temperature range, the thermal design enables full power output up to 50°C and 60% output power at 70°C. Furthermore, the 24 V and 36 V output voltage models have 250 W peak power capability. As well as meeting EN55011/EN55022 class B conducted and radiated emissions, the LS200 meets UL/IEC 60950-1 edition 2 safety approvals and carries the CE mark. It comes with a three-year warranty and measures 199 x 98 x 41 mm.
