Introduce
Voltage and current display relay is a microprocessor-based voltage monitoring device for single-phase AC networks to protect electrical equipment from surge voltage.The device analyzes the main voltage and displays its current value on a digital indicator.Load is switched by electromagnetic relay.The user can set the current voltage value and delay time through the button. The value is stored in non-volatile memory.Aluminum wires and copper wires can be used for connection.
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!
Application
Voltage and current display relay used in administrative,industrial and residential buildings and has the function of protecting single-phase lines:
●Undervoltageprotection;
●Overvoltageprotection;
●Workingundervoltmetermode;
●Overcurrent proteciton.
