Post Glover Dynamic Braking Resistors
... Ohms are specified by the drive manufacturer as the minimum required resistance and are often stated as a range. Post Glover uses a manufacturing tolerance of -0 to +5% to prevent an overcurrent condition on the drive. Watts are stated as either a maximum braking power or continuous braking power. I ...

Electrical ballast
An electrical ballast is a device intended to limit the amount of current in an electric circuit. A familiar and widely used example is the inductive ballast used in fluorescent lamps, to limit the current through the tube, which would otherwise rise to destructive levels due to the tube's negative resistance characteristic.Ballasts vary in design complexity. They can be as simple as a series resistor or inductor, capacitors, or a combination thereof or as complex as electronic ballasts used with fluorescent lamps and high-intensity discharge lamps.
