Model 4110 Modular DC Electronic Load

• Below 1 volt operation
• 300 W, 60 A load modules
• Up to 6 DC loads per 5 1/4" high chassis
• Parallelable "virtual" loads

Application
Model 4110 DC Electronic Loads are designed for use within the S300 Modular Power System. These highly versatile electronic loads may be used in any combination together with the 4100 Electronic Load and/or programmable DC power supplies within the same 6-slot chassis. The use of such wide-capability power modules yields more flexibility, less rack space and lower cost than an assortment of individual DC electronic loads and programmable DC supplies, each having a more limited voltage and current range.

Paralleled Virtual DC Loads
To address higher power requirements, the same type (4100 or 4110s) can be paralleled in software to respond as a single, larger load. All load functions, including slew rate and short-circuit, are then internally synchronized so that the unit-under-test sees a single "virtual" DC load without the dynamic discontinuities associated with paralleling older designs. Should the next application require a different load grouping, reconfiguration is quickly achieved through reprogramming, along with corresponding fixture adjustments, thus extending the system's flexibility with a minimum number of electronic load modules.

Operation Below 1 Volt
With the trend toward lower IC voltages, today's DC electronic loads must anticipate tomorrow's test requirements. The 4110 DC load is optimized at these very low voltages and will deliver full current down to 0.7 V plus linearly reduced current down to 0 V.
