Analog Devices Inc. EVAL-LTPA-RL2000 DC Efficiency Meter
Analog Devices EVAL-LTPA-RL2000 DC Efficiency Meter is designed for use with the LTpowerAnalyzer® Kit (EVAL-LTPA-KIT). The ADI EVAL-LTPA-RL2000 is a compact laboratory instrument for characterizing the efficiency of a power supply design across multiple load current values. With two voltage inputs and two current inputs, the RL2000 is capable of simultaneously measuring both input and output power, up to a maximum of 150W. This DC efficiency meter features a measurement range of ±125V for the voltage inputs, and 10µA, 100µA, 1mA, 10mA, 100mA, 1A, 10A, and 30A for the current input and load. For ease of use, an auto-range function is implemented into the RL2000, allowing the meter to automatically switch to the most appropriate range based on the measured input.
