Specifications, Back Panel Power | PS Audio C250 specification

Back Panel: Power

The C250 is equipped with the standard, internationally accepted 15 amp IEC. This device is labeled, “AC input.” With the supplied power cord, or with another high- end after market cable like the PS Audio Lab Cable II, connect the C250 to a power source.

The C250 is internally equipped with a PS Audio Power Plant. This circuit was spe- cifically tailored for the C250 input stage.

The primary function of this power plant is to regulate and optimize the power line signal for the input stage, however you may still choose to plug the C250 into a PS Audio P1200 Power Plant to obtain additional levels of enhancement. Other- wise, simply connect the C250 directly into your wall receptacle.

The C250 is equipped with a 3 amp fast blow fuse to provide protection for the regenerator (power plant) board. This fuse can be located where it says, “Regenera- tor Fuse.” There is another fuse to provide protection for the main amplifier circuitry, which has a 15 amp slow blow rating. This fuse can be located where it says, “Main Fuse.”

You will find two spare fuses along with this user’s guide should you need them. To obtain specific information on how to replace a fuse, or more importantly to de- termine if the fuse needs replacing, refer to the service section at the end of this manual.

The C250 is capable of handling either 100-120 volts AC input or 220-240 volts AC input. The input AC circuitry in the C250 is auto-sensing. Therefore, the Classic 250 will automatically recognize the correct input voltage and make the ap- propriate internal adjustments to function properly. There are no manual selections or switches to be made by the user to se- lect input voltage.
