Delta UPS Sizing Guide in Kenya
Choosing the correct Delta UPS size in Kenya helps protect your equipment from power outages, voltage fluctuations and unstable mains supply. Whether you are buying a Delta UPS for office computers, CCTV systems, networking equipment, servers or a data centre, the UPS must be sized according to the actual load and required backup runtime.
This Delta UPS sizing guide explains how to estimate your power requirements, choose the right UPS capacity and avoid common sizing mistakes when planning backup power for business and critical equipment.

Why Delta UPS Sizing Matters
An undersized UPS can overload, shut down unexpectedly or provide very short backup time. An oversized UPS may cost more than necessary. Proper sizing helps match the UPS capacity to the equipment load, runtime expectations and future expansion needs.
Prevents Overload
Correct sizing ensures the UPS can safely support all connected equipment.
Improves Runtime Planning
The right UPS size helps estimate how long equipment can stay powered during outages.
Supports Future Growth
Adding spare capacity allows room for extra devices and future upgrades.
Basic Delta UPS Sizing Formula
Start by listing all equipment you want to connect to the UPS, then add the wattage of each device. After calculating the total load, choose a UPS with enough capacity and extra headroom.
Simple rule: Total equipment load + 25% to 30% spare capacity = safer UPS sizing for most office, CCTV and networking applications.
Delta UPS Capacity Guide by Application
Use the table below as a practical starting point when choosing Delta UPS capacity for different applications in Kenya. Final sizing should consider the actual connected load and required runtime.
| Application | Typical Equipment | Suggested Delta UPS Size |
|---|---|---|
| Home Internet Backup | Router, ONT, modem | 650VA – 1200VA |
| Office Workstations | PCs, monitors, routers, printers | 1000VA – 2200VA |
| CCTV Systems | NVR, DVR, PoE switch, router | 1000VA – 3000VA |
| Network Cabinets | Switches, router, firewall, access points | 1500VA – 5kVA |
| Small Server Room | Servers, storage, switches | 3kVA – 10kVA |
| Data Centre | Racks, servers, critical loads | 20kVA and above |
How to Estimate Your Equipment Load
To size a Delta UPS correctly, check the wattage rating of every device that will connect to the UPS. This information is usually found on the equipment label, power adapter, product manual or technical datasheet.
Step 1: List Equipment
Write down every device that needs backup power, including routers, switches, NVRs, servers and monitors.
Step 2: Add Wattage
Add the watt rating of all connected devices to get the total equipment load.
Step 3: Add Spare Capacity
Add extra capacity for safety, efficiency and future equipment growth.
Sample Delta UPS Sizing Scenarios
The examples below show how different environments may require different UPS capacities. These are general examples and should be confirmed with actual equipment load before purchase.
| Scenario | Typical Load | Recommended Approach |
|---|---|---|
| Small Office Internet Backup | Router, switch, ONT, phone system | Use compact Delta UPS with enough runtime for connectivity. |
| CCTV Control Room | NVR, monitor, PoE switch, router | Choose online UPS where uptime and recording continuity matter. |
| Network Cabinet | Switches, router, firewall, access points | Use rackmount UPS if installed in a structured cabinet. |
| Server Room | Servers, storage, core switch, firewall | Choose online UPS with proper runtime and monitoring options. |
VA, Watts and Power Factor Explained
UPS capacity is commonly shown in VA or kVA, while equipment load is often shown in watts. When choosing a Delta UPS, always check both the VA rating and the watt rating because the watt rating determines how much real equipment load the UPS can support.
Important: Do not assume that a 1000VA UPS can support 1000W. Always check the UPS watt rating before buying.
Delta UPS Runtime Planning
Runtime is affected by battery size and connected load. A lightly loaded UPS will usually provide longer backup time than a heavily loaded UPS. If your business needs longer backup time, you may need a UPS model that supports external battery banks.
Short Runtime
Suitable for safe shutdown and short power interruptions.
Medium Runtime
Suitable for keeping CCTV, routers and office systems running during brief outages.
Extended Runtime
Suitable for critical loads that require external battery banks and professional sizing.
Common Delta UPS Sizing Mistakes
Avoid these common mistakes when buying a Delta UPS for business or critical power backup applications.
- Choosing UPS capacity based only on price
- Ignoring the UPS watt rating
- Connecting too many devices to one UPS
- Not allowing spare capacity for future expansion
- Underestimating runtime requirements
- Using basic UPS models for servers or critical systems
- Ignoring battery replacement and maintenance planning
When You Need Professional Delta UPS Sizing
Professional sizing is recommended for larger UPS systems, server rooms, hospitals, banks, data centres, telecom sites, industrial environments and any application where downtime can affect operations. These environments may require site assessment, load calculations, phase configuration review, battery bank planning and installation support.

Frequently Asked Questions
How do I know what size Delta UPS I need?
Add the wattage of all equipment you want to protect, then choose a Delta UPS with enough capacity and spare headroom for runtime and future growth.
Can I connect printers to a UPS?
Laser printers and high-power devices are usually not recommended on standard UPS outlets unless the UPS is specifically sized for that load.
What Delta UPS size is good for CCTV?
Many CCTV systems require 1000VA to 3000VA or more depending on the NVR, PoE switch, camera load and required runtime.
What Delta UPS size is suitable for servers?
Server environments commonly require online UPS systems from 2200VA upward, depending on the number of servers, storage devices and network equipment.
Does a bigger UPS give longer runtime?
A larger UPS may support a bigger load, but runtime depends mainly on battery capacity and connected load. For longer runtime, external batteries may be required.
