General-purpose power supplies boost efficiency
The LS50, LS75 and LS100 have 88 to 264V AC inputs, while the LS150 is switch-selectable for 115 or 230V AC, minimising the cost.
Power supplies cater for short-term peaks
Units provide a very cost and space efficient solution compared with oversizing conventional power supplies just to handle the peak current.
The new PAQ100H is an ideal solution for a wide variety of applications, for example, industrial automation systems and distributed power architectures used in telecommunications and IT servers.
The PAQ100H has a nominal input voltage of 48V over an input voltage range of 36 to 75V.
The new power supplies are available in six output ratings offering 1.5V at 50A, 1.8V at 50A, 2.5V at 45A, 3.3V at 40A, 5V at 35A and, most notably, 12V at 15A.
The availability of a 12V unit is very significant given that industry experts believe that 12V is becoming increasingly important as one of the most significant intermediate bus voltage requirements.
Lambda is one of only a few manufacturers of quarter-brick DC/DC convertors able to produce a 12V unit.
The new DC/DC convertor's baseplate design reduces hot spots and is suitable for heatsink or cold-wall mounting in applications where airflow cooling is not available.
Features include overcurrent, overvoltage and overtemperature protection and automatic restart.
All units comply with global safety approvals including UL60950, CSA C22.2 No 60950-00, EN60950 and CE60950.
High standards of insulation provide on/off isolation voltages of input-to-case of 1000V DC, input-to-output of 1500V DC and output-to-case of 1000V DC.
The power supplies' operating case temperature is from -40C to +125C.
Each unit comes with a two-year warranty. Request a free brochure from Lambda ...
