What are chassis mount resistors?
Chassis resistors are sluggish devices that are against the flow of voltage and are employed to automate signal levels, distribute voltages, bias sensing elements, or endpoint transmission lines, among other applications. These resistors are usually extended and may distribute up to 2500 watts of energy.
Why use chassis resistors?
A metallic wire is coiled around a non-conductive core in chassis resistors with a metal, often aluminum, housing to inhibit or restrict the flow of current and facilitate heat conduction. They could also be made flameproof or contain a corrugated ribbon component for quick cooling. Wire wound resistor technology is used to create chassis resistors, which have a sizable ceramic core that is molded into an extruded aluminum chassis-mount shell. The aluminum enclosure offers improved heat conduction, and the wire wound construction enhances pulse handling.
Types of chassis:
- Manual chassis or frame-full chassis.
- Non-conventional or frameless chassis.
- Estate/Station Wagon.
- Multi-Purpose Vehicle (MPV) / Multi Utility Vehicle (MUV).
- Sport Utility Vehicles (SUV).
Applications of the chassis resistor
Large electrical and manufacturing machinery, motor start or stop cycles, equipment discharge, load test simulation, and dynamic brakes all often require chassis mount. Due to their low-temperature coefficient of resistance (TCR), or the fact that they maintain practically constant resistance across a wide temperature range, chassis resistors are also particularly well suited for applications where the resistor is utilized to aid heat loss and cooling.
