B&K Precision touts multirange DC power supply

Differing from conventional power supplies with fixed outputs, B&K Precision’s Model 9110 DC power supply automatically recalculates the voltage/current limits for each setting and provides 100 W of output power in any voltage/current combination within its rated limits of 60 V and 5 A. By expanding the number of maximum power volt/amp combinations, the Model 9110—a digitally controlled, mixed-mode linear/switching supply—enables you to reduce the number of individual power supplies needed for an application.

The Model 9110 provides 10-mV/1-mA resolution over its full range. The unit can store and recall 4x100 groups of preset volt/amp values, and it features overcurrent, overvoltage, and overtemperature protection.

By automatically recalculating voltage/current limits, the power supply forms a constant-power hyperbolic-shaped boundary. For example, when setting the voltage to the maximum of 60 V, the maximum current value is 100 W/60 V = 1.66 A. For a 20-V setting, the maximum current is 5 A. Full output power of 100 W is possible for all volt/amp combinations that lie on the hyperbolic curve.
