Power fluctuations in arcade machines can lead to performance issues, hardware damage, and even data loss. To mitigate these risks, here are the most effective solutions:

1. Use Voltage Stabilizers: Install a high-quality voltage stabilizer to maintain consistent power supply and prevent sudden spikes or drops.

2. Install Surge Protectors: Protect sensitive components from power surges by connecting the machine to a reliable surge protector.

3. Regular Electrical Maintenance: Inspect wiring, connectors, and power sources periodically to ensure optimal performance and safety.

4. Uninterruptible Power Supply (UPS): A UPS can provide backup power during outages and smooth out minor fluctuations.

5. Grounding and Proper Wiring: Ensure the machine is properly grounded and wired to avoid interference or unstable power delivery.

By implementing these measures, arcade operators can enhance machine longevity and provide a seamless gaming experience.
