Individual emitter segments are capable of directing 5.1 Megawatts.  By comparison, the small personal hand Phasers issued to Starfleet crew members are Type I and II (One and Two), the latter being limited to 0.01MW.  Certain large Planetary defense emitters are designated as Type X+, as their exact energy output remains classified.

In cross-section, the Phaser array takes on a thickened Y shape, capped with a trapezoidal mass of the actual emitter crystal and Phaser-transparent hull antierosion coatings.  The base of an array segment sits within a structural honeycomb channel of Duranium 235 and supplied with supersonic regenerative LN2 cooling.  The complete channel is thermally isolated by a high number of link struts to the vehicle framework.

The first stage of the array segments is the EPS submaster flow regulator, the principal mechanism controlling Phaser power levels for firing.  The flow regulator leads to the Plasma distribution manifold PDM, which branches into two hundred supply conduits to an equal numbers of prefire chambers.  The final stage of the system is the Phaser emitter crystal.
