Description
A power supply or battery only proves itself when something draws real current from it, so a load is essential. The Keysight EL34143A DC electronic load takes that role on the bench. It has one input rated to 150 V and 60 A, with 350 W of power available.
One input, four load modes
First, the load works in constant current, voltage, resistance and power modes. For example, pick constant current to discharge a battery at a steady rate. Then pick constant power to mimic a converter that draws more current as its input voltage drops. Also, static and transient profiles let you step the load and watch how the source recovers.
Seeing the result
A built-in data logger records test behavior over time and offers several result views. In addition, remote sensing and protection features support repeatable runs. Interfaces include LAN and USB, with a GPIB option you can install yourself.
What the Keysight EL34143A DC electronic load handles
- Validating AC-DC and DC-DC power supplies.
- Discharge tests on batteries, chargers and adapters.
- Evaluating LED drivers and automotive electronics.
Size the load to the job
Check three numbers against your device: the highest voltage, the highest current and the power. The ratings do not apply at the same time, because 150 V at 60 A would far exceed 350 W. So do the math for your real operating point. Also ask about the minimum operating voltage in the data sheet, because it matters for low-voltage sources.
Hire or buy through Lost in HCM
Rent the Keysight EL34143A DC electronic load for a validation run, a pilot batch or a stretch of production overflow. Buy it instead when your lab tests supplies every day. Lost in HCM prepares the quote, while SMK Vietnam lists the unit. To begin, request a quote from Lost in HCM with your voltage, current and dates. You can also browse DC electronic load rentals, check the Keysight website, or contact SMK Vietnam.
EL34143A questions
Which load modes does the EL34143A offer?
It runs constant current, constant voltage, constant resistance and constant power. Each mode suits a different type of source, because loads behave differently.
Can I add a GPIB connection?
LAN and USB come standard. A user-installable GPIB option is available too, so mention it in your request if your rack needs it.
What does the built-in data logger record?
It records the test over time and shows the results in several views. As a result, many bench tests need no separate recorder.
