Power failure is a serious issue in Cambodia as power cuts generally happen quite frequently. However, for venues like hospitals or data centres, they cannot be blacked out, not even for a second. Therefore, the usage of UPS has become very important and widespread in Cambodia nowadays.

UPS, or Uninterruptible Power Supply, is an electrical apparatus that provides emergency power to a load when main power fails. However, there are many UPS units out there on the market, so how can we know which one we should use and which one matches your business?

Legrand, a global specialist in electrical and digital building infrastructure, shares with you several tips on how to pick the right UPS.

Choose one with higher Energy Efficiency
When buying a UPS, you should not only consider the price but you have to calculate how the machine will pay you back in the future. Pick the product with a higher power saving system rather than the cheapest product that consumes a lot of energy. For example, with online double conversion technology, Legrand UPS units are 96 percent energy efficient which is 6 percent better than the old versions of UPS on the market, which can help users save up to USD5,000 per year.

Maintenance Service is the key
The most important part of a UPS is not only the machine itself, but you should also consider after-sales maintenance. Imagine if your UPS stopped working or exploded; do you know how to fix it? Legrand provide a highly efficient and fast after-sales maintenance service, thanks to Legrand-certified maintenance staff based in Phnom Penh. Every Legrand UPS also has a two year-warranty of which the extension can be renewed after the expired date.

Be cautious about the Power Factor
In general, most users think that the amount of KVA is equal to the amount of KW when they are buying a UPS. However, it is not always like that. You have to look at the power factor. For example, if a 100 KVA UPS marks the power factor as 0.8, this mean that UPS is capable of only 80 KW, not a full 100KW. However, most of Legrand UPS’s power factor is 1. This can help buyers save more money as they do not have to buy the larger size UPS.

Pick the brand with a good quality battery
Last but not least, you have to be very careful about what batteries are used inside the UPS as it can affect the quality of the product. Every Legrand UPS contains the highest standard battery to ensure the best quality of the UPS.
