Samwha-dsp 63A 40A Din Rail Adjustable Over Voltage Protection Relay Automatic Voltage Protector

general

AVR current and voltage protection relays are designed to protect equipment with sensitive operating voltage and current values ​​from errors that may be caused by supply voltages and overloads.

Device connection is made according to the connection type. Otherwise, the device may be damaged. Adjust the overcurrent and high and low voltage and settings of the device according to the operating current and voltage values ​​of the load you will be using.

Overcurrent error status: If the current value is lower than the current set value (when the device has no error), the current
The value rises above the current set value, the device waits for the set error wait time, then the device opens the relay, the error indicator lights up, and the overload value shown on the current display flashes throughout the error period.

Voltage Error Status: If the mains (input) voltage value is between the high and low voltage setpoints (when the device has no errors), the mains (input) voltage value rises above the high voltage setpoint or below Below the low voltage voltage setting value; the device waits for the set error waiting time, then the device disconnects the relay, the error indicator lights up, and the power input voltage value displayed on the voltage display flashes throughout the error period.

Exit the overcurrent error state: after eliminating the load overcurrent fault, press the switch key twice to manually reset or
cut the power.
Note_1: Manual reset is to avoid secondary damage to the system, and it is not excluded by automatically resetting the system
overcurrent or short circuit.

Exit voltage error state: when the mains (input) voltage value returns to normal / reaches a value between high and high
The low voltage setpoint device waits the set reset wait time before the device energizes the relay. The error indicator is off and the output indicator is on.

Connection Diagram

The neutral wire from the power supply must be connected to the "N" and "L" terminals to set the "input" of the device.
Neutral and phase connections for equipment requiring protection against overvoltage and undervoltage should be taken from the "N" and "L" terminals in the "Output" section of the equipment.
