The Sinotimer SVP-718S is a digital protection relay for single-phase electrical installations, designed to monitor voltage and current, disconnecting the power supply when values exceed the set limits.

The device provides protection against overvoltage, undervoltage, and overcurrent, making it suitable for use in residential and commercial electrical panels. The digital display allows monitoring of voltage and current, while the front buttons make it easy to adjust protection parameters.

• Overvoltage protection – disconnects the power supply when the voltage exceeds the specified limit.
• Undervoltage protection – interrupts the circuit when the voltage falls below the set limit.
• Overcurrent protection – disconnects the power supply when the current exceeds the specified value.
• Digital monitoring – displays voltage and current.
• Automatic reconnection – allows power restoration after the parameters return to the set limits, according to the device settings.
• Adjustable parameters – limits and times can be set via the front buttons.
• DIN rail mounting – for integration into electrical panels.

The front display shows voltage and current values, and the P indicator indicates the operating status. The device has four buttons for navigating settings and controlling operation.

The relay can be used to protect circuits supplying household appliances, electronic equipment, air conditioning systems, and other electrical loads, within the technical limits and installation size of the device.

Important: This product is a voltage and current protection relay, not an AFDD switch, and does not provide residual current protection. It does not replace switches or residual current devices required by the installation. Installation and setup must be carried out by an experienced electrician, in accordance with the electrical diagram and the manufacturer’s instructions.
