DC Electronic Loads Ultra-Compact, Modular Loads Model 4100/4110 ❑ 300 W, 60 A modules ❑ Up to 6 loads in a 5 1/4-inch high chassis ❑ Parallelable “virtual” loads ❑ Below 1 volt operation The Model 4100 and 4110 electronic loads are designed for use within the S300 Power Subsystem. These highly versatile loads may be used in any combination together with DC sources within the same 6-slot chassis. The use of such wide-capability modular loads yields more flexibility, less rack space, and lower cost than an assortment of loads each having limited voltage and current range. BROAD OPERATING ENVELOPE To cover the full spectrum of supply-under-test output voltages, the Model 4100 load operates at full current from 2.1 to 450 V. To meet newer low voltage requirements, the Model 4110 load operates down to 0.7 V and at reduced current down to 0.1 V. In the constantcurrent mode, both loads have three ranges in order to assure the necessary low-end resolution for both set and measurement values. Website: www.w ellking.com PARALLELED “VIRTUAL” LOADS To address higher power requirements, the same type (4100 or 4100s) can be paralleled in software to respond as if they were a single larger load. All load functions, including slew rate and short-circuit, are then internally synchronized so that the supplyunder-test sees a single “virtual” 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, thus extending the system’s flexibility with a minimum of load modules. OPERATION BELOW 1 VOLT With the clear trend toward lower IC voltages, today’s loads must anticipate tomorrow’s test requirements. Both the 4100 and the 4110 will operate below 1 V at reduced current levels, with the latter being optimized for operation at these very low voltages.
