Dual Loop Master Controller
-
The Xcite System Master Controller provides all dual loop functions needed for accurate closed loop control and display of the static and dynamic test variables, while producing the highest electro-hydraulic frequency response. At the heart of each Xcite System is the Master Controller, a compact electronic control package which provides all of the controls and displays necessary to operate a controlled force or torque exciter system. The Xcite Master Controller is unique in that it provides electro-hydraulic excitation over a broad frequency range, unprecedented by any previous electro-hydraulic excitation system. It achieves its great frequency range through the use of sophisticated circuitry, high voltage inputs to the servovalve and compression control of the dynamic feedback variable in addition to the conventional servo control of the static loop. Static parameters such as force or displacement may be matched with dynamic control variables such as force, displacement, velocity, acceleration or strain for maximum test flexibility.

Phase Monitors
-
NAI''s AC- and DC-powered Phase Monitors are used to protect three-phase loads from damage due to phase reversals or phase absence. Contacts may be used to disconnect the load or to operate alarm circuits or both. Upon application of power, the output relay energizes if all phases are connected and the phase sequence is ABC. If any phase becomes disconnected or if the phase rotation is abnormal, the relay immediately de-energizes. These monitors are specifically designed for rugged defense and industrial applications.
