Plasma regulator

A plasma regulator or an EPS regulator was a component used to regulate plasma in the electro-plasma system of a starship or starbase.

On a starship, plasma regulators were crucial to the functioning of the warp drive. When the USS Defiant (NCC-1764) arrived in the 22nd century mirror universe, it was sabotaged by the removal of two of its plasma regulators. ''

Around stardate 50929.4, O'Brien had to recalibrate a shipment of EPS regulators to prevent them from interfering with Deep Space 9's artificial gravity grid.
