РН-263t is designed to protect household and industrial electrical equipment (such as refrigerators, air conditioners, washing machines, television, video, and audio equipment) from unacceptable voltage fluctuations in the network and the consequences of neutral (ground) disconnection.

Key Features of РН-263t:

Voltage Monitoring:

• Displays the current voltage in the network and the state of the relay contacts (load status).
• Current Monitoring: Measures and displays the current consumed by the load, along with the active power.
• The relay disconnects the load if the current exceeds a predefined threshold.

Error History:  Stores information about the last five malfunctions in non-volatile memory, providing a history of power failures.

Overheating Protection:  Equipped with protection against overheating caused by poor contact of conductors in the terminals, which may result from contamination or inadequate clamping pressure.

Functional Modes:

• Voltage Relay: Provides protection against voltage fluctuations.
• Digital Multimeter: Displays the network voltage, active power, and consumed current.

Power Supply:

РН-263t is powered by the circuit that supplies the load, making it easy to install without requiring an external power source.
