How to choose UPS uninterruptible power supply in Mozambique

There are various types of uninterruptible power supply (UPS) systems available to provide protection from power problems. Understanding the differences allows you to choose the right UPS for your specific needs. A standby UPS is the most affordable and common type for home and small business use.

Unlike generators or other backup power supplies that can take a few seconds to kick in, a UPS system ensures no break at all in the power current, hence the name uninterruptible power supply. The UPS battery backup carries the critical load until the longer-lasting backup power supplies can engage and take over the job.

A UPS, at its most basic, is a battery backup power system that supplies power long enough for equipment to properly shut down when utility power fails. It helps prevent loss of data and minimizes the stress a hard shutdown causes on your electronic equipment.

And the power factor. A UPS system with a power factor of only 0.8 can provide only 80 percent of its rating. A UPS system with a “unity” (or 1.0) power factor will provide 100 percent of its rated capacity. You can specify load capacity from 350VA up to 20kVA using the UPS Product Selector.

What do I need to know about battery chemistry? The UPS Selector tool allows you to specify different types of battery chemistry, such as lead-acid or lithium-ion.

A Standby UPS system is the most basic topology. When incoming power drops below or surges above safe voltage levels, a Standby UPS system switches to battery power, providing a bridge of power until utility power is restored. Line-Interactive UPS systems feature Automatic Voltage Regulation (AVR) functionality.
