Product Description

Product Description

YC9VA Single Phase Voltage Relay Adjustable Over Under Voltage Protectorwith LED Display

General

YC9VA votage 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.

Application

YC9VA/YC9VA2 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;

Overcurrent proteciton.

Operation

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.
