Voltage and current display relay is a microprocessor-based voltage monitoring device for single-phaseAC networks toprotect electrical equipment from surgevoltage.The device analyzes themain voltage and displays itscurrent value on a digitalindicator Load isswitched by electromagnetic relay.The usercan set the currentvoltage value and delay timethroughthe button.The value is stored in non-volatile memory.Aluminum wires and copperwires can beused for connection.
General
Function description:When a phase of L1,L2,L3 overvoltaged,undervoltaged orphase lacked,the relay will be disconnected and automatically search for the normalphase,and switch to open the relay of the normal phase,switching priority
L1>L2>L3!
