Over / under voltage monitor (incorporating phase failure)

• The Electro 11 pin plug-in range of control and timing devices are to be installed into a standard 11 pin base making installation easy and convenient.
• Monitors own supply.
• Relay will only operate whilst the supply voltage is within the presettable OVER and UNDER voltage limits and all three phases present and in sequence.
• Providing effective power supply supervision and protection.

Features:

• Output 10A SPDT
• 10 second start-up delay
• Latch facility incorporated
• 180 second response delay
• Over / under voltage protection
• Measures on own power supply
• LED indication for over / under volts
• Upper and lower limits separately adjustable
• Upper and lower limits separately adjustable
• Phase failure protection / phase reversal protection
• Measures if phase to neutral voltage are within set limits, present and in sequence
• Monitoring relay and measuring relay for upper / lower phase to neutral voltage control
