Product Details
Application
YC9VA voltage and current display relay used in administrative, industrial and residential buildings and has the function of protecting single-phase lines:
Undervoltage protection;
Overvoltage protection;
Working under voltmeter mode.
Operation and Installation Functions
When a voltage is applied to the device, the digital indicator will display the current value of the voltage in the network.
A flashing light indicates that there is no voltage on the output of the device. If the supply voltage is within the set range, after Ton (default is 30 seconds), the load will turn on and the indicator will stop flashing. If the voltage is not within the specified range, the load will not be connected to the line until the voltage returns to normal. Meantime, if the voltage is lower than the set lower limit during the restart, the error indicator will flash. If the voltage is higher than the set upper limit, the error indicator will remain on.
1. Install and secure the relay.
2. Connect the wires to the relay according to the schematic.
3. Set the desired voltage value.
4. Set the required response time.
