New 1U High Chroma DC Power Supply with Web Interface for Remote Monitoring

New 1U High Chroma DC Power Supply with Web Interface for Remote Monitoring

The development of electronic components often requires long-term or repeated testing during quality assurance or product verification stages. For example, aging of semiconductor power components, long-term durability of active and passive components, LED and laser diode, aging of solar modules, and similar tests all necessitate a long-running and stable DC power supply. Moreover, processing multiple […]

How to Test a DC-DC Converter for Quality and Reliability

This post describes how to test a DC-DC converter. DC-DC converters are devices used to convert one DC voltage to another. DC-DC converters are used in a wide variety of products from portable devices such as cell phones, notebooks and laptop computers to electric vehicles and avionics. The range of input voltages and output voltages […]

Question: Why is Accuracy and Multiple Ranges important?

Answer:  Most accuracy specifications for Test Equipment are listed as % rdg + % fs. Example: 0.1% rdg + 0.1% fs This is a percentage of the reading or measurement + the percentage of the Full Scale for the range you are in. If a DC Electronic Load has only one range, say 80 amps […]
