... WATCH THE DUTY CYCLE Servomotors are likely to expose the DC power supply to unusual extremes of load variation. More so, at least, than better-behaved loads like computers and instrumentation. Depending on the servo's duty cycle, the power supply can require an output rating nearer the amplifier's ...

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.
