UPS Buying Guide: How to Choose the Right UPS in Bangladesh

Buying a UPS (Uninterruptible Power Supply) is essential if you want to protect your computer, router, office equipment, or servers from sudden power cuts and voltage fluctuations. This UPS Buying Guide will help you understand the key factors so you can choose the perfect UPS for your home or business.

1. Identify Your Power Requirement (VA/Watt Capacity)

Before choosing a UPS, calculate the total power consumption of the devices you want to connect.

How to calculate?

Add up the wattage of each device and choose a UPS with 25–40% extra capacity for safety.

Example:

• PC: 300W

• Monitor: 50W

• Router: 10W
  Total: 360W → Choose a 600VA–1000VA UPS

2. Decide the Type of UPS You Need

There are three main UPS types:

Offline UPS (Standby UPS)

• For basic home/office use

• Budget-friendly

Line-Interactive UPS

• Better voltage regulation

• Suitable for small to medium businesses

Online UPS (Double Conversion)

• Best protection

• Zero transfer time

• Ideal for servers, medical equipment & professional workstations

Choose based on your power sensitivity and workload.

3. Check Backup Time

Backup time depends on battery capacity.

General guideline:

• Light use (router/PC): 5–15 minutes

• Office/Workstation: 10–30 minutes

• Server setup: 30+ minutes (Online UPS with external batteries)

More backup time = bigger battery = higher price.

4. Look at Battery Type & Quality

Most UPS use sealed lead-acid (SLA) batteries.

What to consider:

• Battery capacity (Ah)

• Brand reliability (Long, Leoch, CSB, etc.)

• Warranty (minimum 1 year recommended)

For heavy usage, Online UPS often supports external batteries for longer backup.

5. Transfer Time (Very Important)

Transfer time = time taken to switch from main power to battery.

• Offline UPS: 2–10 ms

• Line Interactive: 2–4 ms

• Online UPS: 0 ms (perfect for sensitive devices)

If you use servers, medical tools, or video editing machines, Online UPS is mandatory.

6. Output Waveform

UPS output can be:

Modified Sine Wave (cheaper)

• Basic computers and routers

• Budget UPS

Pure Sine Wave (premium)

• Servers

• Gaming PCs

• Professional equipment

• Medical devices

For expensive desktops or workstations, always choose pure sine wave UPS.

7. Voltage Regulation (AVR)

UPS with AVR protects your devices from:

• High voltage

• Low voltage

• Sudden spikes

• Brownouts

Line-interactive and online UPS have better AVR systems.

8. Number of Sockets & Output Ports

Make sure your UPS has enough outlets for:

• PC + Monitor

• Router

• CCTV

• Printer (optional)

Choose models with surge protection ports for extra safety.

9. Brand, Warranty & After-Sales Service

A UPS is only as good as its support.

Recommended to check:

• Warranty period (1–2 years)

• Battery warranty

• Nationwide service centers

• Authenticity (buy from trusted sellers)

Buying from a reliable retailer like Orient Computers ensures genuine products with full warranty support.

10. Price vs. Performance

UPS prices in Bangladesh vary depending on:

• Capacity (VA)

• Battery size

• Features (AVR, LCD display, pure sine wave)

• Online vs Offline UPS

Choose based on your need — not just the cheapest option.
