Phase Failure Three Phase Sequence Under & Overvoltage with Time delay

Specification :

• Under and Over voltage monitoring
• Monitors own three phase, 3-wire supply
• Detects incorrect phase sequence and phase loss
• Adjustable Trip levels and Time delay
• SPDT Relay output
• 17.5mm wide, DIN Rail mount
• Monitoring function: Under/Over voltage
• Monitored supply voltage*: 110V, 208V, 380V, 400V or 415VAC
• Trip level: Under: 75 – 95%/Over: 105 – 125%
• Hysteresis: ≈2%
• Time delay: 0.2 – 10s
• Output: SPDT 8A @ 250V (AC1)
• Dimensions(mm): W:17.5 x H:89 x D:66.5

The product monitors it’s own three-phase supply and for the output relay to energise, all phases must be present, the phase sequence correct and the phase to phase voltages within the set Under/Over trip levels. If any of these conditions are not met, the relay will de-energise.
