The SINOTIMER SMQ5-63 is an automatic transfer switch designed for safe switching between two single-phase power sources, such as the electrical grid and a generator or inverter. It ensures continuous supply to consumers with automatic switching in case of primary source failure and automatic return after voltage restoration.

The switch incorporates both automatic operation and manual control, making it suitable for residential, commercial, and technical applications where power supply safety is essential.

Principle of Operation: In automatic mode, the switch monitors the normal power source. When the voltage drops or disappears, the load is automatically transferred to the backup source. Once the primary source voltage returns, the device switches back automatically.

Key Features:

• Front selector for choosing between automatic or manual operation
• Rotary switch for direct mechanical switching
• LED indicators showing voltage presence on normal and backup sources
• Clear markings for Main Power (N) and Emergency/Backup Power (R)

Electrical Connections:

• Normal power input: L phase, N neutral
• Backup power input: L phase, N neutral
• Output to load: L phase, N neutral

Electrical Characteristics:

• Maximum rated current: 63A
• Operating voltage: 230V AC
• Frequency: 50/60Hz
• 2-pole switching L + N
• Automatic and mechanical modes
• High switching capability for continuous applications

Installation: Mount on panel or metal base, secure with screws through appropriate holes in the casing. Recommended for installation inside electrical panels. Installation must be performed by certified personnel.

Applications:

• Backup generator systems
• Photovoltaic installations with secondary source
• Residential and commercial buildings
• Technical rooms, halls, laboratories
• Applications where continuous power supply is critical

Important notes:

• Does not provide short-circuit protection
• Does not replace circuit breakers or fuses
• Use with appropriate protections recommended
• Does not allow both sources to operate simultaneously
