This enhances reliability and continued operation ‐Vout of your application. If the output current is too high, the converter will enter the short circuit condition.

If the output voltage drops too low (approximately 97% of nominal output voltage for most models), the PWM Figure 4 Measuring Output Ripple and Noise (PARD) controller will shut down. Following a time-out period, the PWM will restart, causing the output voltage to begin rising to its appropriate value.

Passive resistance loads are employed and the output is set to the maximum voltage. If you set up your own emissions testing, make sure the output load is rated at continuous power while doing the tests.  The recommended external input and output capacitors (if required) are included. Please refer to the fundamental switching frequency. All of this information is listed in the Product Specifications. An external discrete filter is installed and the circuit diagram is shown below.

IR Transparent The system includes a precision low flow-rate anemometer, optical window variable speed fan, power supply input and load controls, Variable temperature gauges, and adjustable heating element. Unit under speed fan test (UUT) The IR camera monitors the thermal performance of the Unit Under Test (UUT) under static steady-state conditions. A IR Video special optical port is used which is transparent to infrared Camera wavelengths. Both through-hole and surface mount converters are soldered down to a 10"x10" host carrier board for realistic heat absorption and spreading. Both longitudinal and trans- verse airflow studies are possible by rotation of this carrier Heating board since there are often significant differences in the heat element dissipation in the two airflow directions. The combination of Precision adjustable airflow, adjustable ambient heat, and adjustable low-rate Input/Output currents and voltages mean that a very wide anemometer range of measurement conditions can be studied. 3” below UUT The collimator reduces the amount of turbulence adjacent to the UUT by minimizing airflow turbulence. Such turbu- lence influences the effective heat transfer characteristics Ambient and gives false readings. Excess turbulence removes more temperature heat from some surfaces and less heat from others, possibly sensor causing uneven overheating. Both sides of the UUT are studied since there are differ- Airflow ent thermal gradients on each side. The adjustable heating collimator element and fan, built-in temperature gauges, and no-contact IR camera mean that power supplies are tested in real-world conditions.
