Description

NHR’s 4300 DC Loads have been used across a variety of major company initiatives and remains a highly competitive product on the market. The modular 4300 DC electronic load is ideal for rack and stack ATE customers, military as well as aerospace applications. This flexible load measurement system can be reconfigured easily to test products in parallel which better simulates real-world conditions and improves testing time. The capability to combine up to 16 loads into a single chassis, with fast transient speed and synchronous measurement, opens several new test strategy possibilities. The 4300 DC electronic load is perfect for applications that require simultaneous testing of multiple power conversion UUTs or multi-output power supplies.

Another major advantage is the built-in 4301 Digital Power Analyzer that provides accurate UUT input measurements dedicated to each tester channel. This advanced digital measurement system is capable of measuring devices in a few seconds. The analyzer includes a power meter, multi-meter, and oscilloscope that together provides a powerful test solution.

This distributed measurement capability allows measures each output from a multi-output power conversion device simultaneously rather than sequentially. Not only does this dramatically reduce the overall test time but also provides far better channel-to-channel performance measurements including dynamic cross effects. This flexible DC load and measurement system allows you to reconfigure the loading arrangement as required by future test needs.
