Abstract: Systems, apparatuses, and methods for a modular resistor grid system include a mount and a plurality of modular resistor grid assemblies that interchangeably couple to the mount. At least two modular resistor grid assemblies are in the plurality. Each has a housing and a plurality of resistor plates. Each housing has input and output terminals. Each plurality of resistor plates is connected between the input and the output terminal of a housing. Each resistor plate has a thickness, and each plurality of resistor plates provides a target electrical resistance for a modular resistor grid assembly. A first modular resistor grid assembly has a first number of resistor plates with a first thickness. A second modular resistor grid assembly has a second number of resistor plates with a second thickness. The first number of resistor plates is greater than the second number. The first thickness is greater than the second thickness.

Abstract: Systems, apparatuses, and methods relate to modular resistor grid assemblies having a “black box” resistance. The modular resistor grid assemblies include a first plurality of first resistor plates having a first thickness disposed within a first housing. The first housing has a first input and output terminal. The first resistor plates provide a target electrical resistance between the first input output terminal. A second plurality of second resistor plates having a second thickness smaller than the first thickness is disposed within a second housing. The second housing has a second input and output terminal. The second resistor plates provide the target electrical resistance between the second input and output terminal. The first and second housing interchangeably couple to a resistive braking system. The first plurality includes a first number of first resistor plates, and the second plurality includes a second number of second resistor plates less than the first number.
