Power Line Monitor:-This is a ideal item to monitor and control single phase supply.Receives single phase supply with earth and gives supply at 3 sockets on front facia of the box.If earth is not connected the supply trips indicationg Line Fault.If supply voltage is below 207Volts,then the supply trips indicating Undervoltage fault.If supply voltage is above 253Volts,then the supply trips indicating Overvoltage fault.The PLM also limits sudden current surgesand has surge protection against power surges.Main features are:1)Indications as PLM On,Line fault,Power ON,Overvoltage,Undervoltage2)Limits current surges3)Protects connected equipment from voltage fluctuations4)Suppresses voltage surges5)Fuse protection for overloading
