Describes the steps for prototyping for the first time when a high voltage is encountered. In addition, we will recommend the best instrument you need to complete these tasks.
In the first boot process, we first high-pressure stage and low-voltage phase separated. We recommend using AC power with current limiting. Once the AC power is selected, starting with the design of the lowest AC voltage, this is a critical step that helps to reduce the risk of major blows, such as poor welding, poor assembly, or PCB design errors.
Now start measuring AC input voltage and current. We recommend using a corresponding grade differential probe and current probe. If you use a clamp current probe to measure the low AC input current that is not absorbed by the system, you will actually increase the current seen by the probe. To this end, the circuit conductor is simply cycled through the clamps many times. Remember to divide the current reading by the number of turns.
Now ready, the device under test is powering up. Before using power, use an oscilloscope or power analyzer on the AC input and enable logging to ensure that the incoming and incoming events are captured. We recommend using the PA1000 Power Analyzer, which is optimized for fast, efficient and accurate measurement of power consumption. This power analyzer also provides an influx of current mode to test the peak current during the influx of current.
