Electronic Loads

What is a Programmable Electronic Load?

Electronic loads offer a useful means of absorbing electrical energy. Modern electronic loads are constructed by banks of High-Power FETs, attached to heat sinks. The FET's source and drain connections are connected to the external energy source. The FET's "ON" resistance is controlled by a microprocessor-controlled control system in such a way that it can arrange for the load to provide:

  1. Constant Resistance
  2. Constant Voltage
  3. Constant Current

How can Power Supplies and Solar cell Arrays be Tested?

In the past banks of power resistors or rheostats were connected to the power source to simulate a required load. Although they would in most cases provide a fixed resistance, the resistance could not be changed dynamically so their usefulness as a test facility was limited.

A Programmable Electronic Load is able to change its resistive load value dynamically. This means that the load value can be changed under computer control to perform a sequence of tests to evaluate the performance of the power source.



How are Electronic Load Banks Used?

The load bank is useful in the laboratory and production test environment for testing a wide range of equipment:

  • Power Supplies
  • Batteries
  • Generators
  • Solar Cell Arrays
  • Fuel Cells

In addition to testing power generators, power drivers can also be tested such as:

  • LED Display Panels (dedicated LED Loads are available for this)
  • Motor and Power Drivers

In all cases, the programmable load allows dynamic performance to be tested including transient load testing, making it ideal for use in a production test facility.
