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.

Serial AC Power Sequencer
90-200-001
AC Power Sequencer
Each power outlet can be programmed to switched on in sequence with a specific timing delay. The delay can be staggered to ensure that order dependent systems - like PXI - can be switched on and off in an orderly way with just one operation. A staggered start up also limits the inrush current associated with the powering up of equipment, including earth current inrush, placing less stress on cabling and leakage breakers. Power on or off instructions can be initiated from either the front panel switch or via the serial interface.
