Automated Power Transfer: High-Performance ATS & Auto Changeover Panels

At Plus 3 Group, we specialize in the design and manufacture of Automatic Transfer Switch (ATS) and Auto Changeover Panels. These systems are the critical link in your power infrastructure, ensuring that hospitals, residential complexes, and industrial plants never suffer from a total loss of power.
 

Our panels act as the intelligent "decision-maker" for your electrical system, instantly switching between utility power and backup sources without requiring human intervention.

How the Auto Changeover Process Works
The primary function of an ATS panel is to manage the start-stop sequence of your generator based on the health of the grid:
 

Grid Monitoring: The panel continuously tracks the incoming utility supply.

Seamless Transition: Upon a power failure, the ATS prevents the load from connecting until the backup generator has reached the correct frequency and voltage.

Emergency Activation: Once the generator is ready, the switch transfers the building’s electrical load to the emergency power source.

Automatic Restoration: When the utility power is restored and stabilized, the ATS commands the generator to shut down after a proper cool-down cycle, returning the load to the mains.

Specialized Dual-Mains Solutions for Fire Safety
In compliance with stringent building regulations, Plus 3 Group offers unique Dual-Mains Automatic Changeover Panels. These are specifically engineered for high-rise buildings and critical infrastructure that utilize duplicate power supplies.

Life-Safety Priority: In the event of a fire or power failure, the panel automatically swaps to the secondary supply to ensure continuous operation of firefighting lifts and emergency ventilation systems.
 

Advanced ATS Controllers
The "brain" of our panels is the ATS Controller, which utilizes sophisticated software subroutines and high-reliability relays. This controller governs the transfer switch with precision, ensuring that the mechanical components operate only when electrical conditions are 100% safe.

Engineering Excellence & Range
As a leading manufacturer in India, we build our panels to survive the most demanding conditions:

Quality Fabrication: Manufactured as per Indian Standards (IS), using premium raw materials and laser-cut precision.
 

Flexible Capacity: We supply systems ranging from compact 32A units for small backup requirements to massive 3200A ACB-based systems for large-scale industrial installations.

Switching Technology: Depending on your needs, we utilize high-speed circuit breakers or motorized changeover switches to guarantee infrastructure uptime.
