What is a DC Programmable Electronic Loads?
A DC programmable electronic load is a type of instrument that simulates a system working and consuming power. A DC programmable load is used by the power supply, EV battery, or other manufacturers who want to thoroughly test their power sources. Manufacturers of these products need to test their supplies dynamically. For instance, simulating an EV during operation to demonstrate compliance to quality and safety standards.

Before buying a DC electronic load, you need to find out a couple of things:
- What are the lowest & highest voltage points that you need the DC electronic load to read?
- What is the highest current operating point that the electronic load may need to read?
- Does the DC electronic load have front panel connections? This may be critical to reduce cable drop and increase the accuracy of the electronic load.
- What is the maximum power the electronic load need to prduce?
- Can your electronic load be quickly reconfigured for changing applications?

The Array 3751A is a 240 V 150 A 2.0kW Programmable DC Electronic Load. This unit is designed for heavy-duty applications such as grid testing, battery station testing. On top of that, the unit is a user-friendly HMI, as well as an RS232 interface to support SCPI and Labview.
The Array 3751A programmable DC offers four sets of test programs:
- Firstly, constant current, from 6 amps up to 150 amps at 1.0 mA resolution.
- Secondly, constant voltage, from 0 to 240 volts at 1mV resolution.
- Finally, constant resistance and constant power, up to 2,000 watts at 1mW resolution.
Beyond these standard tests, there are a few auxiliary functions that allow more specific testing: high-speed sequencing, high-speed transient, short circuit, and battery discharge.
- High power application.
- Auxiliary functions that allow more specisic testing.
- Limited to high power testing serniro only.
In conclusion, from a life-cycle perspective, battery performance and health really are the key to it all. In addition, the battery is the EV’s most expensive component in an electric vehicle. Moreover, the degree of degradation will affect the vehicle’s residual value (which helps answer the cost question from above), and will also have a direct impact on the maximum usable range over time. This is one of the reasons the manufacture wants to test these batteries’ health before shipping them out. In other words, the test engineers would need to pick the correct DC electronic that fit the requirement of the test is very important. Finally, failing to do so could ultimately cause an accident that we could all prevent.
