Automatic Transfer Switches (ATS)

For any commercial or industrial operation, maintaining a continuous power supply is essential. An Automatic Transfer Switch (ATS) acts as the critical bridge between your main utility grid and your backup generator. Maruka Technology manufactures robust ATS units that detect power failures instantly and manage the transition to backup power without manual intervention.

Our systems are engineered to ensure a seamless changeover, minimizing the disruption caused by blackouts. Once the utility power is restored and stabilized, the ATS automatically switches the load back to the mains and commands the generator to cool down and shut off. This automation guarantees that your facility remains operational around the clock, even when unattended.

Safety Interlocks

We utilize mechanical and electrical interlocks to physically prevent the mains and generator supplies from connecting simultaneously, eliminating the risk of short circuits.

Voltage Monitoring

To prevent unnecessary switching during minor fluctuations, our ATS units monitor voltage stability, ensuring a transfer only occurs during a genuine outage or brownout.

Instant Response

The system continuously monitors the mains supply. Upon detecting a failure, it initiates the generator start signal within seconds to restore power rapidly.

Manual Override

Every unit is equipped with a manual operation handle, allowing maintenance personnel to operate the switch safely during servicing or system testing.

Simple Steps to Process

The logic within an ATS is designed to protect your equipment. We program specific time delays to ensure smooth transitions between power sources.

01

Detection

The controller senses a loss of phase or voltage drop in the utility grid and waits a preset time to confirm it is not a momentary spike.

02

Transfer

Once the generator reaches the correct frequency, the switch isolates the mains and engages the generator supply to power the load.

03

Restoration

When utility power returns, the system verifies its stability before transferring the load back and shutting down the generator.

Operational Advantages

Installing a reliable ATS eliminates the need for manual generator operation, which can be dangerous and slow. It provides peace of mind knowing that your critical systems—such as refrigeration, servers, or production lines—are protected.

  • Ensures business continuity during power outages.
  • Eliminates human error during power switching.
  • Protects sensitive equipment from voltage instability.
  • Reduces downtime and associated financial losses.
