The WTHD Online Single Phase UPS is a reliable and efficient power backup solution designed to keep your computers, networking devices, and sensitive electronics running smoothly during power outages or voltage fluctuations. Available in various capacities including 1000VA (1KVA), 2000VA (2KVA), 3000VA (3KVA), 4000VA (4KVA), 5000VA (5KVA), 6000VA (6KVA), and up to 10000VA (10KVA), this UPS supports both 110V and 220V systems, making it suitable for a wide range of applications and locations

One of the key features of this WTHD UPS is that it is an online double conversion model, which means it continuously provides clean and stable power. Unlike offline or line-interactive UPS systems, the online UPS converts incoming AC power to DC and then back to AC. This process eliminates problems like voltage spikes, surges, and dips, ensuring your equipment receives a consistent and high-quality power supply. This is especially important for sensitive devices such as computers, servers, and medical equipment that require stable electricity to operate safely and efficiently

With its single-phase design, the WTHD UPS is ideal for homes, offices, small businesses, and IT setups that do not require three-phase power. It is easy to install and use, offering multiple outlets to connect critical devices. The UPS also features built-in battery management to provide longer backup times and protect the battery life. You can trust it to automatically switch to battery power when the main power fails, giving you enough time to save your work, perform an orderly shutdown, or continue operations without interruption

The WTHD Online Single Phase UPS is also designed with user-friendly LCD displays and alarm systems that keep you informed about battery status, load conditions, and power quality. Its compact and sturdy build allows it to fit well into different workspaces without taking up much room

The WTHD Online Single Phase UPS is a dependable power backup solution for protecting your valuable electronics against unexpected power failures and electrical issues. Whether you need to support a single computer or multiple devices, these UPS models provide peace of mind, ensuring your systems stay up and running when you need them the most. Choose the right capacity from 1KVA to 10KVA according to your needs, and rely on WTHD for powerful, stable, and continuous power protection
