YC9VA Voltage Protection Relay

General
YC9VA voltageand current display relay is a microprocessor-based voltagemonitoring devicefor single-phase AC networksto protectelectrical equipment from surge voltage.The deviceanalyzes the main voltage and displays its curent valueon a digitalindicator Load is switched by electromagnetic relay.The user canset the current voltage value and delaytime throughthe buttonThe value isstored in non-volatile memory.Aluminum wires and copper wires can be used forconnection.
