What is programmable DC electronic load?
A programmable load is a type of test equipment or instrument which emulates DC or AC resistance loads normally required to perform functional tests of batteries, power supplies or solar cells.
How do you calibrate DC electronic load?
The calibration is basically a three step process. First, the control board current measurement is calibrated by injecting DC voltage into the “Parallel In” connector. Once this is done, the load voltage measurement is calibrated by injecting voltages into the “Remote Sense” input.
How does a DC electronic load work?
The electronic load is operated In CV mode to typically test and load a current source device – for example, a current charging circuit. The electronic load modulates its resistance to reach the programmed voltage. The load monitors the input voltage through a voltage divider.
What are DC loads?
A DC electronic load is a testing device that can sink current and absorb power from a DC power supply to ensure that it is working correctly. Often used in manufacturing and engineering, a DC load offers essential data on battery life and performance.
How do you test DC load?
Use a power supply, DC load, and a computer to analyze voltage versus current characteristics. Connect the power supply in parallel to the DC load. Set the power supply to its rated voltage and set a preset value for current. The DC load should display the rated voltage if power supply’s output is on.
What is DC electronic?
Direct current (DC) is an electric current that is uni-directional, so the flow of charge is always in the same direction. As opposed to alternating current, the direction and amperage of direct currents do not change. It is used in many household electronics and in all devices that use batteries.
What is the difference between AC and DC load?
Another important difference between AC and DC is the magnitude of the voltage. DC voltage is low-level voltage while AC is high-level voltage….Comparison Chart.
| Parameters | AC (Alternating Current) | DC (Direct Current) |
|---|---|---|
| Type of Load | It can be resistive, inductive or capacitive. | Only resistive |
What is the use of DC load?
DC Electronic loads are growing in popularity as more electronic devices convert and store energy. They are utilized in testing most sources of DC, including batteries, solar panels, LED drivers, DC-DC converters, and fuel cells.
Why is DC used in electronics?
Direct current is used in any device that has a circuit board because the chips within these devices require a steady, unidirectional flow of electrons to operate and store data. Every home PC has a DC inverter built into the system, which then provides DC style power to the rest of the devices inside the case.
