Avetlink AK Controller for Stable Lighting Operation
Oxidized contacts, loose connections, and uneven loads can cause lighting controllers to stop working or make lamps flicker.
The Avetlink AK controller is designed to balance current distribution in the lighting system. Regular inspection and maintenance help keep connections reliable and reduce unexpected failures.
According to the supplied product description, proper maintenance can achieve:
- 60% fewer short-circuit faults.
- 70% less light flickering.
- More than one additional year of service life.

Applications and Maintenance
The controller is intended for workshop lighting and outdoor advertising displays. Important inspection points include loose terminals, contact oxidation, and bulging capacitors.
Basic visual checks can help identify these problems. Internal inspection should only take place after the power is disconnected and any stored electrical energy has been safely discharged.
Key Features
- Straightforward inspection: Basic visual checks do not require specialized measuring instruments.
- Load balancing: The source specifies compatibility with a 24-tube system using four lamps connected in parallel.
- Stable operation: Secure connections and correctly matched loads help reduce interruptions and flickering.
Maintenance Tips
1. Inspect wiring contacts every three months. Follow the manufacturer’s approved cleaning and corrosion-protection instructions.
2. Keep each lamp’s power at 50W or less.
3. Keep the total connected load within the controller’s 200W rated limit.
