HIGH-FLEXIBILITY DC LOAD SYSTEM

APPLICATION

The L4000 DC Electronic Load System is the most flexible, mid-to-high-power DC electronic load system available. It is intended for applications requiring a great number of different types of modular DC loads that can be either paralleled under program control or physically reconfigured as test requirements change. This high degree of flexibility is achieved through a chassis that will accept five different sizes of DC load modules, each of which is available in three maximum voltage limits.

BROAD CONFIGURABILITY

The L4000 DC Electronic Load System can be configured to match an unusually wide assortment of loading requirements by selecting from sixteen types of electronic load modules. These include 150, 300, 600, 1200 and 2.5kW power levels at 60, 200, 400 & 500V maximums. The smaller electronic loads require fewer card slots, thereby allowing up to 16 loads in a single 10½-inch chassis. The user can mix and match electronic load modules and voltage ranges to suit any type of loading requirement. Additional electronic load modules and higher power levels can be provided through a slave chassis controlled through the same GPIB address.

VIRTUAL LOADING

To take flexibility a step further, similar DC electronic load types can be grouped as "virtual loads" under program control thus minimizing the number of different load modules needed to meet a particularly wide variety of requirements. The benefits of this flexibility are lower test station costs, less rack space and ease of adapting to future load requirements.
