No Transformer Required! This model operates from
power supplies that rectify the line directly with
full optical isolation between signal and power stages.

The power supply should deliver sufficient power P ,
to supply the power delivered to the motor, and the
power lost in the amplifier.
In general, the supply voltage V should be larger
than the motor’s nominal voltage rating for the
absolute maximum voltage rating. Consult the motor
manufacturer for more information.
The current delivered by the supply can be calculated
from the equation I = P / V. Furthermore, the power
supply should be able to handle any current surge that
occurs during power up. The Copley amplifier limits
the current surge to 37 Amps maximum on power-up.

The capacitor used in the bridge rectifier circuit must be
able to keep the voltage ripple, or Vrip , at sufficient
levels and the capability of storing 10 times the energy
regenerated from the load. The capacitor C may be
calculated from this equation:
C = I / (120Hz * Vrip)
