Demonstrate DC Electronic Load Fundamentals

DC electronic loads characterize a power supply’s responses to various load conditions. The N6790 series load provides modes for current, voltage, resistant and power.

EL30000 Series DC Electronic Loads

The EL30000 Series bench DC electronic loads provide superior performance in compact bench form factor. A single and dual-channel model is available with up to 600 W – ideal for design verification of consumer power supplies, batteries, battery modules, solar panels, LED drivers, and power converters.

Bench DC Electronic Load with Scope Mode

A DC electronic load with two channels and a built-in scope can capture and analyze cross-regulation. Power supplies with multiple voltage rails will have cross-regulation. It is important to characterize the cross-regulation to ensure that it does not affect the device. In the past, this measurement required multiple instruments. Today, a single instrument, the EL34243A bench electronic load with a built-in scope mode, can generate a unique dynamic load and capture the effects on adjacent voltage rails.
