Electronic loads minimise test bench space

Keysight Technologies’ EL30000 Series bench DC electronic loads offer a compact bench form factor with a built-in data logger that delivers insights for immediate, real-time decisions, and minimises the need for additional instruments with an accurate system that measures voltage, current and calculates power.

These bench electronic loads enable customers to test a wide range of power sources, perform both static and dynamic tests to ensure devices can output constant energy, as well as handle a sudden increase or decrease in demand.

Multiple ranges allow accurate measurements for small and large devices from zero to 150V. 

Using the built-in measurement system eliminates the need for an external digital multimeter, shunts and associated wiring.

Device manufacturers and design engineers will be able to:

  • Measure voltage and current accurately with a fully integrated voltmeter and ammeter that simultaneously measures the device under test (DUT) voltage and current.
  • Capture measurements over time with the built-in data logger that continuously logs voltage, current and power to a data file.
  • Create, capture and display fast transients with a dynamic load profile and built-in scope mode that digitises the voltage and current, and shows the results, reducing measurement set up complexity.
  • Simplify tests with standard operating modes: constant voltage (CV), constant current (CC), constant resistance (CR) and constant power (CP).
  • Connect with USB, LAN (LXI Core) and optional general-purpose interface bus (GPIB) to easily measure, capture and display results.

"Our customers are focused on accelerating their next-generation designs," said Christopher Cain, vice president and general manager of Keysight's Electronic Industrial Products. "Simplifying the testing of batteries and the electronics design at the heart of portable electronics, enables faster time to market and maximum performance."

An electronic load is an instrument designed to test sources by presenting various resistances and measuring the response. Device manufacturers and design engineers use electronic loads to test power devices such as power supplies, batteries, battery modules, solar panels, fuel cells, LED drivers and power converters.
