Line Voltage & Phase Sequence Detector
208D-208/240VAC
The Model 208 Line Voltage & Phase Sequence Detector provides essential monitoring for industrial electrical systems. Operating at 208/240V and 400Hz, this device offers continuous connection for reliable performance. Its primary function is to indicate normal phase rotation (ABC or CBA) and identify missing phases (A, B, or C). This capability is crucial for maintaining operational integrity and preventing potential equipment damage due to incorrect phasing or power interruptions. The detector's clear lamp indicators provide immediate visual feedback, allowing for prompt identification of system anomalies. Its utility lies in its direct, unambiguous reporting of critical power conditions.

FAQs
How does the detector indicate normal phase sequence?
The detector indicates normal phase sequence (ABC or CBA rotation) through specific lamp patterns. For ABC rotation, lamps ABC, A, B, and C are lit. For CBA rotation, lamps CBA, A, B, and C are lit.
What visual indication is provided if a phase is missing?
If Phase A is missing, lamps ABC, CBA, B, and C are lit. If Phase B is missing, lamps ABC, CBA, A, and C are lit. If Phase C is missing, lamps ABC, CBA, A, and B are lit.
What are the primary voltage and frequency specifications for this device?
The Line Voltage & Phase Sequence Detector operates at 208/240V and a frequency of 400Hz.
