amiciSmart 220V Under Voltage and Over Load Protection

Product Information

Application
The product is designed to protect single-phase lines from over-voltage, under-voltage, and over-current faults. It can automatically power off the line in case of a fault and restore the connection after a time delay when the voltage or current returns to normal. It also provides protection against transient over-voltage and can disconnect the line in case of unstable voltage, sudden power-off, or power-on due to faults.

Product Features

• Automatic restoration of line connection after voltage or current recovery
• Protection against false operation caused by transient over-voltage
• Disconnection of the line in case of unstable voltage or faults
• No damage to the product itself even at peak fault voltage

Application
Over Voltage and Voltage Protective Device with Auto-Reclosing Function (OUPA) is an intelligent protector integrated with an over-voltage protector, under-voltage protector, and over-current protector. In case of over-voltage fault, under-voltage fault, and over-current fault in line, this product can instantly power off to prevent electrical equipment from being burnt. The over-voltage, under-voltage, and over-current values of this product can all be set up by yourself and can be adjusted based on local practical conditions.

Product Features

• In case of over-voltage fault, under-voltage fault, and over-current fault in single phase line, the product can power off the line and can automatically restore connecting the line over a time delay after the voltage or current of the line is recovered to normal condition.
• In case of transient overvoltage in line, the product can protect the equipment from false operation.
• In case the line is subject to unstable Voltage or sudden power-off and power-on due to a loosened connection and another fault, the product will disconnect the line.
• When the fault voltage of the line reaches the peak, the product itself will not be damaged.

Normal use and installation conditions

Normal use conditions

Ambient air temperature
Ambient air temperature shall not be more than +55°C and not less than -20°C and the 24H average temperature shall not be more than +35°C.

Altitude
The altitude of the installation place shall not exceed 2000m.

Atmospheric conditions

Humidity
The relative air humidity at the installation place shall not be more than 50% when the ambient air temperature is +40°C; Relative humidity may be high under low-temperature conditions.

Usage
After being installed, the protector can be wired by the user. Wherein, a cross-section of the wire shall be selected by the standard applicable and based on the rated current of the protector. Pay attention to the locations of incoming and outgoing wires and the phase sequence before powering them on for use.

Notes

• The user shall follow relevant procedures and pay attention to the following items when carrying out various operations or tests to ensure the correct and safe use of the product
• The input and output shall be corrected and connected based on the product marking. (Wherein, the load current shall be less than the protective current of the product.)
• Neutral line N cannot be improperly connected and shall be reliably wired; otherwise, the protector may not work normally.
• Before powering on, please carefully check whether the wiring is correct, whether the load matches the protective current of the product, and whether the binding screw is tightened; otherwise, the product may be damaged.
• After powering on the product, do not touch any live part to avoid electric shock.
• This product shall be combined with micro circuit breaker to play the role of short-circuit protection; otherwise, the product may not be able to realize load limit protection in case the input or load end of the product appears short circuit.
• As the product has an automatic reset function after the product plays the role of protection and acts, it is necessary to remove the load (electric appliance) and check the circuit; otherwise, the product will be frequently connected and disconnected from the load. Finally, the product or its circuit may be burnt due to frequent overload connection and disconnection for a long time.
• Products that are not used for a long time shall be moisture-proof and dust-proof. Before use, they shall be debugged according to the above contents, and they can be put into operation only when they are normal.
• This product has no isolation function. Please disconnect the front circuit breaker when maintaining circuit.
• The maximum sustainable voltage of this device is 440V. In case of surge, this product will destroy itself without damaging your appliances. Your appliances will be safe.
