UPS & Voltage Protection in Bangladesh

Load shedding and voltage swings can shut down a PC or damage its parts. A UPS in Bangladesh gives you battery backup to save your work, while stabilisers and surge protectors smooth the voltage.

Types of UPS

• Offline (standby): simple and low cost, switching to battery during a cut.
• Line-interactive: adds voltage correction (AVR), a good choice for home and office PCs.
• Online: continuous protection, best for servers and sensitive equipment.

Choosing the right size

When buying a UPS in Bangladesh, remember that VA is not watts. A UPS delivers roughly 60 percent of its VA rating in real watts, so a 1000VA unit supports a load around 600W. Add up the watts of your PC, monitor and router, and pick a UPS comfortably above that. Backup time depends on load and battery size, and a larger battery gives more minutes.

What a UPS should not run

Do not connect air conditioners, refrigerators, heaters or laser printers to a small UPS. They draw high current and can overload it. A UPS is a protection device, not a safety guarantee.

Care tips

Keep the unit in a cool, dry and ventilated place. Charge and use the battery regularly, and expect to replace the battery every few years. Read the specifications on the product page, and check the label and battery in the parcel on delivery.

Frequently asked questions

How many VA do I need for a desktop PC?

A typical home PC with a monitor needs 650VA to 1000VA, depending on the graphics card and power supply.

What is the difference between UPS and a stabiliser?

A UPS has a battery to keep devices running during a cut, while a stabiliser only corrects low or high voltage.

How long will a UPS run my computer?

From a few minutes to over an hour, depending on load and battery. It is designed to let you save work and shut down safely.

Can I connect a router to a UPS?

Yes, routers use little power, so a UPS keeps your internet running for a long time during load shedding.

Do I need a surge protector with a UPS?

Most UPS units already include basic surge protection. A separate surge strip is useful for devices that do not need a battery.
