Notes on Electronic Loads.

Electronic loads and load banks are used to test electrical and electronic equipment. They mimic load requirements for testing and troubleshooting purposes. There are four basic types of electronic loads: benchtop, slot, modular and system. Benchtop loads are relatively inexpensive, but  limited in terms of range and accuracy. Slot loads measure a single set of variables and are similar to benchtop loads. Modular loads include a computer chassis and are designed for applications with changing load configurations. Although modular loads more than one chassis are available, devices with a single chassis can be configured to act as a single load in dynamic modes. System loads are designed for near-continuous duty and include an integral transient generator. They are more expensive than other types of electronic loads, but provide a wider range of features.

Selecting electronic loads requires an analysis of performance specifications and product features. Input specifications include power, voltage, current, and frequency. Modular loads also vary in terms of number of loads per chassis. As a rule, smaller electrical loads require fewer card slots. Measurement type, efficiency, and emulation mode are additional considerations when selecting electronic loads. Measurement types include voltage, current, peak-current, frequency, crest-factor, power-factor and true power. Efficiency, a measure of power, is usually expressed as a percentage. Electronic loads provide up to five emulation modes: constant-current, constant-voltage, constant-resistance, constant-power, and short circuit. Alternating current (AC) and direct current (DC) outputs are characterized as high, low, or medium power. In terms of features, electronic loads often include a graphical user interface (GUI) and integral software. Test results can be sent to a digital front panel, a printer, or a personal computer (PC).

Electronic loads are used for design verification, multiple unit production testing, and troubleshooting inbound devices for repairs. Some products are used to test AC power supplies, DC power supplies, switching power supplies, or uninterruptible power supplies (UPS). Others are designed to test fuel cells, inverters, telecommunications rectifiers, batteries and battery charges. Programmable electronic loads are used with automatic testing equipment (ATE) and a variety of units under test.
