Description

      The QUS20-120-NHDR is a very good product. If you want to use it you must learn about it rightly. Here you can know some features about it. The QUS20-120-NHDR has ten features. The first feature is that it is 48vin, isolated, and 4:1 fixed conversion ratio (12v Nominal Out). This feature is very important, because the feature makes it used widely. You also should know the second feature, which is 240 watt max output. The third feature may make you know how good the QUS20-120-NHDR is. The QUS20-120-NHDR is parallel for higher output power. The forth feature of the QUS20-120-NHDR is ±10% current share accuracy. The fifth is over-temperature protection. The sixth feature is that the QUS20-120-NHDR is 96% efficiency. The seventh feature is that the QUS20-120-NHDR is remote enable on the condition of primary side. The eighth feature is that the QUS20-120-NHDR is positive or negative enable logic. The ninth is that the QUS20-120-NHDR has current limit. Here is the last feature that the QUS20-120-NHDR is vertical mount .
      There is some notes you should also know. The first is that Vin = 48Vdc, Ta = 20°C, Airflow = 200LFM unless otherwise noted. And the second is that input reflected ripple current is specified when measured with a 120F 63V electrolytic capacitor across the input pins. The next note is that output ripple voltage is specified when measured with a 270F electrolytic and a 10F ceramic capacitor at the converter output pins. You should also know that de-rating curves are conducted in a controlled environment. End application testing is required to ensure the hot spot temperature is below the maximum specified. Recommended airflow direction is input to output or cross-wise. For output to input airflow subtract 3A from derating curves. The last thing you should know is that transient response is specified with 270F electrolytic and 10F ceramic at the converter output pins.
