Power Testing Equipment

Power Supplies and Electronic Loads are forms of test equipment that go together like Signal Generators and Signal Analyzers. Power supplies generate precise amounts of energy to power a device under test (DUT) while electronic loads provide the means to measure the output of an energy source, such as an uninterruptible power supply (UPS), an inverter, or a battery. Power supplies and loads are available for AC or DC testing, over a wide range of power ratings and capacities. Finding the right match for an application is a matter of understanding the specifications for each type of instrument and the performance levels needed for the measurements in mind.

AC Power Sources and DC Power Supplies are defined by a voltage range, maximum voltage, current range, maximum current and total power. Some supplies may also be rated for a short-duration, peak current level above and beyond the maximum rating, as might be used for inrush current testing. In addition, AC power sources have adjustable frequency ranges and may have standard frequency settings, such as sine wave outputs at 50/60 Hz, to simplify testing of standard AC-powered devices. AC power sources are usually differentiated in terms of their signal purity by the amount of distortion at a standard output setting, such as 50/60 Hz for ease of comparison with other AC Power Sources.
