FAQs

An electronic load, in the context of electrical engineering, refers to a device designed to simulate the electrical load that a circuit or power source would encounter in a real-world scenario. The load is used for testing and characterizing various electronic components. These components can include power supplies, batteries and voltage regulators.

An electronic load can actively draw current from the device under test (DUT) and provide a controllable load to help operators assess the performance, stability and efficiency of the DUT. An electronic load can help operators evaluate and assess the behavior of electronic and electrical systems that will encounter varying operating conditions.

The electric load of current, otherwise called the electrical current load, refers to the amount of current drawn from a power source by a device or circuit. The electric load of current is typically measured in amperes (A) and represents the flow of electric charge through the load.

The basic electronic load is a simple resistive load, otherwise called a dummy load or fixed load. The basic electronic load consists of resistors that provide a constant resistance value to create a load used to test electronic components and circuits.

A basic electronic load is usually not programmable or adjustable. It serves as a straightforward load for specific resistance testing purposes.

An electronic load bank is a specialized device used to test and validate power sources, such as batteries or generators, to name two. The load bank offers precise and adjustable electrical loads. This allows operators to control the testing of power systems under different conditions. Different industries that benefit from this device include power generation or telecommunications, for example, to help assess equipment performance and capacity.

A DC electronic load is a device designed to simulate and apply controlled electrical loads to direct current (DC) power sources. A DC electronic load enables operators to test and evaluate the performance of DC power supplies, batteries or other DC-powered electronic systems. The device performs this task by drawing specific current levels and enabling precise measurements and assessments.

An example of a DC load is the EA EL Electronic High Power Density DC Electronic Loads from EA Elektro-Automatik, which are designed for “two-quadrant operation,” also called the source-sink principle, which is a combination of a load and a power supply.

The EA ELR regenerative DC electronic load is a regenerative load that can recover over 96.5% of current back to the local grid, resulting in high energy savings.

In terms of electronic testing and power systems, the DC in DC load stands for direct current. A DC load is a device or component used to apply a controlled electrical load to a DC power source to help operators test and evaluate DC power supplies, batteries or electronic systems.

Several types of DC loads are used in electronic testing and power applications. These include resistive loads with fixed resistance, electronic loads with programmable control, battery simulators for battery behavior, regenerative loads that can absorb and return energy, dynamic loads for simulating real-world applications, and high-power loads designed for testing high-current and high-power electronics. The choice of DC load depends on the testing needs and characteristics of the devices or systems under evaluation.

A programmable DC electronic load is a versatile testing device that applies controlled electrical loads to DC power sources. It allows operators to program the device to simulate various load conditions digitally. It allows operators to adjust current, voltage and other parameters. This makes it a valuable tool to test and characterize power supplies, batteries and electronic components.

To set a DC electronic load, the operator would first input the desired parameters, such as current and voltage limits, using the device controls or a software interface. Once configured, the operator can activate the electronic load to apply the specified load conditions to the DC power source to allow testing and evaluation.

There are different types of DC loads used for testing and evaluation purposes. These include:

  • Resistive loads that offer fixed resistance values
  • Electronic loads, which are programmable and versatil
  • Battery simulators that mimic battery behavior
  • Regenerative loads which can absorb and return energy
  • Dynamic loads, which can simulate dynamic load profiles, and
  • High-power loads that test high-current and high-power electronics

The selection of DC load type will depend on specific testing requirements and the characteristics of the devices or systems that require evaluation.
