TDK-Lambda Americas Inc. in San Diego is introducing the RFE1000 1-kilowatt, single-output AC-DC power supply series in a 1.61-inch high 1U package for stand-alone or distributed power architectures in applications such as radio communications, factory automation, test and measurement, robotics, and RF power amplifiers. These power converter devices are for power electronics applications requiring reliable 24-, 32-, or 48-volt bulk power. Voltage adjustment as wide as +20 percent and -10 percent is possible. The device operates from a universal input of 85 to 265 volts AC with PFC, with efficiency as high as 88 percent. Power system designers can use the RFE1000 power supplies individually, or connect as many as eight units in parallel to form an N+1 redundant power system with built-in O-ring diodes. Each power supply has variable-speed cooling fans and can operate in temperatures ranging from 0 to 70 degrees Celsius. The RFE1000 has a power density of 10.5 watts per cubic inch, and measures 12 by 5 by 1.61 inches. Overvoltage, overcurrent, and over-temperature protection are standard. System monitoring features include opto-isolated signals for DC-OK, AC-fail, and over-temperature warnings, along with an LED indicator for DC-OK.
