An ATS automatically switches between two power sources to ensure continuous power supply to critical loads.  The "TOQ3-63" part indicates the model and that they can handle up to 63 Amps of current. The "/2P" means it's a 2-pole switch (for single-phase DC systems), while "/4P" signifies a 4-pole switch (likely for dual-pole DC systems or potentially for switching both positive and negative lines in a single-pole system for added isolation). These devices are used in applications where a power outage on the primary source requires an immediate switch to a backup source like a battery or generator, preventing any interruption to the connected equipment.

Features of TOQ3-63/2P and TOQ3-63/4P Dc Automatic Transfer Switch ATS:

• Dual Power Input: Accepts two DC power inputs (e.g., main supply and battery backup).
• High Current Capacity: 63A rating allows for handling significant DC loads.
• 2-Pole (2P) and 4-Pole (4P) Options:
• 2P is likely for single-phase DC systems (switching positive and negative).
• 4P may be for dual-pole DC or for enhanced isolation in single-pole by switching both + and - lines.
• Fast Switching Time: Minimizes interruption to the load during transfer (exact time varies, but often under 100ms).
• Indicator Lights: Typically LEDs to show which power source is currently active.
• Manual Override (Sometimes): Some models might have a manual switch for testing or maintenance.
• DIN Rail Mounting: Designed for easy installation in standard electrical panels.

Specifications  of TOQ3-63/2P and TOQ3-63/4P Dc Automatic Transfer Switch ATS:

• Rated Current: 63A (both /2P and /4P)
• Voltage: This is the key missing spec! DC voltage ratings must be known for safe use. Common DC voltages in ATS are 12V, 24V, and 48V, but others exist. You cannot assume a voltage.
• Number of Poles: 2 or 4 (as indicated in the model name)
• Switching Time: Usually <100ms (but confirm with the specific model)
• Operating Temperature: Will have a specified range (e.g., -20°C to +60°C)
• Standards Compliance: Likely to comply with relevant IEC or other electrical safety standards

Uses:

• Telecom/Datacom: Ensuring uninterrupted power to critical communication equipment.
  Renewable Energy Systems: Switching between solar/wind power and battery backup.
  Emergency Lighting: Providing backup power to essential lighting circuits.
  Security Systems: Maintaining power to alarm systems, CCTV, etc.
  Industrial Control: Protecting sensitive control circuits from power outages.
  UPS Systems (Smaller Scale): Can be a component in smaller DC UPS setups.

Benefits:

• Continuous Power: Prevents downtime and disruptions due to power failures.
• Automation: Automatic switching removes the need for manual intervention.
• Reliability: Designed for frequent switching and long-term reliable operation.
• Protection of Equipment: Ensures stable power supply, protecting connected devices from voltage fluctuations or sudden power loss.
• Increased Safety: Provides a safe and controlled way to switch between power sources.
