UPS Systems for Sale in South Africa

South Africa is just one of several global countries where the notion of energy services and energy service businesses have grown and developed over the past decade.

When it comes to electricity generation, distribution, and consumption, South Africa leads the continent in every category. However, the country’s energy situation is deteriorating; rolling load shedding has been in effect continuously since November 2022, reliability is eroding, and it is the only country where electrification rates are declining. The year 2023 is on track to be the worst on record, with load shedding being implemented almost daily.

Having said that, the situation makes for a thriving value chain for equipment suppliers in South Africa’s energy services market.

By implementing Toshiba’s UPS systems, you can safeguard your company from the effects of power failures and eliminate downtime altogether. When a power outage is detected, our UPS systems for sale instantly switch over to battery power, making them the most efficient available. Instead of experiencing data loss, device failure, or time-consuming delays, you can look forward to a productive and trouble-free experience.

Toshiba is a global leader in electronic manufacturing, delivering cutting-edge technology, products, and services. The Group is dedicated to improving people’s lives by making them less dangerous, more convenient, and more fruitful. With a shared commitment to the future and a strong sense of duty to safeguarding our global environment, we pool our creative energies and convictions to make a difference.

What Is a UPS System?

A UPS ensures continuous power to any attached devices. A UPS can immediately provide clean battery backup power and surge protection for plugged-in, sensitive equipment in the event of an interruption or fluctuations in the mains power supply.


UPS Size Matters

A device’s maximum wattage and maximum VA (volt-ampere) ratings are listed. The combined ratings of all attached devices must not exceed the maximum values specified. Watts are a measurement of the actual power used by the device, while volt-amps are the result of multiplying the voltage applied to the device by the current drawn by the device.

Although VA rating is always equal to or greater than watt rating, watt rating and VA rating might vary widely for computers and UPS units. Power factor refers to the ratio of watts to VA and can be written as a decimal (e.g., 0.8) or a percentage (e.g., 80%). The power factor is the most important aspect in selecting the appropriate size UPS for your needs. The Output Watt Capacity of your UPS should be 20–25% greater than the total power consumption of all connected devices.


Type of UPS Systems

There are many aspects to consider while deciding on a UPS to meet your needs. Choosing a UPS for power backup requires careful evaluation of the load size, location, and criticality of the equipment to be protected, as well as the budget.

There are three primary UPS setups: online double conversion, line-interactive, and offline (also known as standby and battery backup). The UPS system type is defined by the power flow within the device.


Online Double Conversion

When generated, AC power is steady and free of contaminants. However, it is prone to voltage sags, spikes, and full failure during transmission and distribution, which can disrupt computer operations, wipe data, and damage equipment. Only online double conversion technology offers complete defence against all these power issues, guaranteeing the greatest standards of network security.

Because it first converts AC power to DC and then back to AC, an online UPS system is often referred to as a “double conversion” system. This configuration of AC-DC/DC-AC protects the load against fluctuations in the mains supply. An online UPS ensures that the power you receive is clean and consistent every time.



A line-interactive UPS provides power conditioning and battery backup. This device works well in locations with power fluctuations but few outages. Line-interactive UPS systems tolerate wide input voltage swings before switching to battery backup.

Line-interactive UPS controls power fluctuations better than offline systems, even without battery backup. Line-interactive UPS’s voltage boost circuitry and input voltage range are key advantages. More range means more protection.

Line-interactive UPS uses an always-on inverter. The inverter filters and regulates voltage by charging the battery when AC input is normal and switching to battery power when input fails. Line interactive UPS systems drain their batteries more quickly than online UPS systems that condition power through double-conversion.



Standby UPS

Standby UPS, often known as offline UPS, is cost-effective. Offline UPS systems that transition to batteries quickly can prevent power anomalies and survive short outages. Most spikes are prevented by an offline UPS, but minor sags and surges are not.

The unit’s power range before switching to battery backup determines offline UPS quality. When the power goes off, a broader range means less battery depletion and more backup time. More UPS battery backups mean lower battery life.

Small workplaces, home computers, and other non-critical applications benefit from this technology. Offline UPS is ideal for low power capacity and cost. Desktops, gaming consoles, workstations, wireless networks, and other electronics are protected by offline UPS technology. It gives ample runtime during power outages to save work in progress and orderly shutdown equipment. Offline UPS systems provide power backup and basic surge protection.
