Automatic Changeover With Current Limiter (ACCL) Single Phase

ACCL (Automatic Changeover with Current Limiter) is a type of electrical switchgear that automatically switches the power source between the main supply (grid) and a backup source (generator or inverter) while limiting the current to avoid overloads during backup operation.
It has Microcontroller based control and processing & SMPS based power supply.

Key Functions of ACCL

Automatic Source Changeover

• Switches from main supply to generator/inverter when the main fails.
• Switches back to the main supply when it is restored.

Current Limiting

• Limits the amount of current (amperage) drawn from the generator or backup source.
• Prevents overloading of the generator, which may not be able to handle full building loads.

Protection Features

• Overload and voltage fluctuations are managed on Generator operation.
• Auto recovery from overload condition.

Benefits

• Ensures uninterrupted power supply.
• Prevents overloading backup power systems.
• Reduces manual intervention during power outages.
• Helps in load management and energy efficiency.
