What Is a UPS?

A UPS (Uninterruptible Power Supply) provides backup power during outages and stabilizes voltage, ensuring continuous operation of critical devices like computers, routers, and surveillance systems.

Types of UPS Systems

AC UPS (Alternating Current UPS)

AC UPS systems power devices that operate on AC electricity such as computers, servers, and televisions.Pros:

• Supports high-power devices
• Versatile for office environments

Cons:

• Lower efficiency for small loads
• Bulky and noisy

DC UPS (Direct Current UPS)

DC UPS systems are designed specifically for low-power DC devices like WiFi routers and CCTV cameras.Pros:

• High efficiency
• Compact and silent
• Longer backup for routers

Cons:

• Limited to DC devices

AC UPS vs DC UPS – Which Should You Choose?

• Choose AC UPS for computers, servers and office equipment
• Choose DC UPS for routers, modems, CCTV and IoT devices

Using an AC UPS for low-power devices often results in poor efficiency and shorter backup times.

Conclusion

Understanding the difference between AC UPS and DC UPS helps you choose the most efficient backup solution. Selecting the right UPS improves reliability, reduces energy loss, and extends equipment life.
