In today's technology-driven world, ensuring uninterrupted power is not a luxury—it's a necessity. From protecting sensitive equipment to maintaining seamless business operations, the right Uninterruptible Power Supply (UPS) can be the difference between uptime and costly downtime.

At Paradyne, we provide a wide range of UPS solutions tailored to the specific needs of businesses across sectors. In this guide, we explain how to assess your power requirements, the different types of UPS systems available, and how to make an informed decision for your facility.

Understanding Your Power Load

Before choosing a UPS, it is essential to evaluate your total connected load—the equipment that must remain powered during an outage.

Steps to calculate your power requirement:

1. List all devices to be supported during a power failure (e.g., servers, routers, PCs, printers, CCTV, etc.).

2. Note the power consumption of each device in watts (usually mentioned on the label).

3. Add up the wattages to get total consumption.

4. Account for the power factor (typically 0.7–0.8). Divide the total watts by the power factor to get the load in volt-amperes (VA), which corresponds to UPS sizing in kVA.

Example:
If your equipment consumes 2,800 watts and the power factor is 0.8, the required UPS capacity is:

2,800 ÷ 0.8 = 3,500 VA or 3.5 kVA

At Paradyne, we assist customers in assessing actual load conditions and recommending the right UPS capacity, ensuring you avoid the risks of under- or over-sizing.

Determining Battery Backup Requirements

The second key decision is the desired backup time—how long the UPS should keep your systems running during a power outage. This can range from 15 minutes (to allow safe shutdown) to several hours for continuous operation.

Battery sizing considerations:

Battery capacity is measured in ampere-hours (AH). To calculate required AH:

• Multiply your load in watts by the desired backup time (in hours).

• Divide this by the system DC voltage multiplied by a safety factor (typically 0.8 to account for efficiency and temperature loss).

Example:
For a 2,000W load with 30 minutes (0.5 hour) backup and a 180V battery system:

Battery AH = (2,000 × 0.5) ÷ (180 × 0.8) = 6.94 AH

In practice, businesses opt for 15–26 AH batteries depending on redundancy, depth of discharge, and desired backup. Paradyne supplies reliable SMF-VRLA batteries from reputed brands such as Exide and configures battery banks to meet specific customer backup needs.
