⚡ UPS Buying & Maintenance FAQ
🔍 General Questions
Q1. What is a UPS and why do I need one?
A UPS (Uninterruptible Power Supply) provides backup power during outages and protects against power fluctuations. It ensures your equipment stays online, preventing data loss and hardware damage.
Q2. How do I choose the right UPS?
Start by calculating your total power load (in VA or kW) and determine how long you need backup power. Consider your equipment type, environment (home, office, industrial), and whether you need features like remote monitoring or compact size.
Q3. What types of UPS systems are there?
- Standby (Offline): Basic protection for home/small office use.
- Line-Interactive: Mid-tier option with voltage regulation.
- Online (Double Conversion): Premium protection, ideal for mission-critical systems.

Q4. How much runtime will a UPS give me?
It depends on the connected load and battery capacity. Most product pages include estimated runtimes under typical loads.
Q5. Should I consider Lithium-ion UPS batteries?
Yes, especially for edge environments or critical operations. Lithium-ion batteries offer longer life, faster recharge, higher temperature tolerance, and reduced maintenance—though they cost more initially.
⚙️ Installation & Setup
Q6. Can I install a UPS myself?
Small, plug-and-play models are easy to install. For larger, hardwired systems, we recommend professional installation for safety and performance.
Q7. Where should I position my UPS?
Install in a dry, well-ventilated, and accessible location. Avoid direct sunlight, heat sources, or areas prone to dust and moisture.
Q8. Do UPS units need ventilation?
Yes. Proper airflow prevents overheating. Never block vents or stack equipment directly on top of the UPS.
🛠 Maintenance & Performance
Q9. How often should I test my UPS?
Run a self-test every 3–6 months. For business-critical applications, regular load testing and professional checks are recommended.
Q10. What’s the battery lifespan?
-
VRLA (Lead Acid): 3–5 years
-
Lithium-ion: 8–10 years
Battery life depends on usage, temperature, and maintenance routines.
Q11. Can I replace the UPS battery myself?
Yes, most smaller UPS units support DIY battery replacement. Always refer to the user manual or contact support for guidance.
Q12. How do I know if my battery needs replacing?
Watch for reduced runtime, warning alarms, failed self-tests, or visible swelling/leakage on the battery.
🔧 Troubleshooting & Monitoring
Q13. Why is my UPS beeping?
Frequent beeping usually means the UPS is on battery, the battery is low, or there’s a fault. Check the display or consult the manual for error codes.
Q14. Can I monitor my UPS remotely?
Yes. Many UPS models offer network cards or software for remote monitoring via web browser or SNMP tools.
Q15. What should I do during a long power outage?
Shut down non-essential devices to extend battery life. After power returns, allow the UPS to recharge fully before use.
🛡 Warranty & Support
Q16. What’s covered under warranty?
Typically, warranties cover defects in materials and workmanship. Battery warranties may vary by type and model—check specific product documentation.
Q17. Do UPS systems need regular service?
For high-dependency environments, yes. Regular service ensures battery health, system integrity, and up-to-date firmware.
⚡ PDU Buying & Maintenance FAQ
General PDU Questions
Q1: What is a Power Distribution Unit (PDU)?
A PDU is a device designed to distribute electrical power to multiple pieces of equipment in a rack or enclosure. They’re common in data centres, server rooms, laboratories, and other critical infrastructure environments.
Q2: Why are PDUs important in IT and critical infrastructure?
They ensure reliable, organised power delivery, help prevent overloading, and often provide monitoring, switching, or automation to improve uptime and energy efficiency.
Q3: What is a Basic PDU?
A Basic PDU is a simple, fixed-outlet power strip for rack mounting. It distributes power without monitoring or remote control features.
Q4: When would you choose a Basic PDU?
When you only need reliable power delivery and do not require remote management, monitoring, or switching — for example, in non-critical or standalone applications.
Q5: What are the advantages of a Basic PDU?
- Cost-effective
- Simple to install and maintain
- Fewer components to fail
Q6: What is a Metered PDU?
A Metered PDU provides real-time power consumption data, usually via an onboard display. It lets you see load levels to avoid overloading circuits.
Q7: What’s the difference between a Metered and a Basic PDU?
A Metered PDU shows power usage; a Basic PDU does not. This is important for capacity planning and preventing overload.
Q8: Who should use a Metered PDU?
Ideal for environments where you need to balance loads across circuits but don’t need remote monitoring — such as smaller server rooms.
Q9: What is a Switched PDU?
A Switched PDU allows you to remotely turn individual outlets on or off. This enables remote reboot of connected devices without physical access.
Q10: When is a Switched PDU most useful?
In situations where equipment is hosted in remote sites or colocation facilities, and you need to perform resets without sending a technician.
Q11: Are Switched PDUs secure?
Yes, reputable models offer password-protected access and encrypted management protocols to prevent unauthorised control.
Q12: What is a Managed PDU?
A Managed PDU combines the features of a Switched PDU with advanced monitoring — such as outlet-level metering, environmental sensor integration, and network-based management.
Q13: What can you monitor with a Managed PDU?
- Voltage, current, power factor, and energy consumption
- Outlet-specific usage
- Environmental conditions (temperature, humidity) with optional sensors
Q14: Why choose a Managed PDU?
Managed PDUs help with energy optimisation, capacity planning, remote troubleshooting, and proactive failure prevention.
Q15: How do I choose the right type of PDU?
- Basic: Lowest cost, simple distribution only
- Metered: Adds local load monitoring
- Switched: Adds remote outlet control
- Managed: Adds both control and detailed monitoring
Q16: What factors should I consider before buying?
- Number and type of outlets
- Voltage and amperage requirements
- Mounting orientation (vertical/horizontal)
- Features (monitoring, switching, network interface)
- Brand reliability and support
