Model 4100 Modular DC Electronic Load

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

Application
Model 4100 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 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.

Broad Operating Envelope
To cover the full spectrum of unit-under-test output voltages, the Model 4100 DC Electronic Load operates at full current from 2.1 to 450 V. In the constant-current mode, the 4100 Load provides three ranges in order to assure the necessary low-end resolution for both set and measurement values

Paralleled Virtual DC Loads
To address higher power requirements, the 4100 Load 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.
