Power outages and voltage spikes can shut down your machines, corrupt data, and cost you time and money. When a server or a production line loses power, you may lose work, damage equipment, or miss important deadlines. The APC Easy 3S 20 kVA Online UPS, Pure Sine, 3-Phase, White Tower gives you clean, uninterrupted power so your critical loads stay on and run safely.
APC Easy 3S 20 kVA Online UPS, Pure Sine, 3-Phase, White Tower with APC
Stay online even when the grid fails. This APC unit is a double-conversion online UPS that supplies a pure sine wave to three-phase equipment. It is built for data centers, factories, and any place that cannot afford a power interruption. If you need reliable power for servers, PLCs, or heavy machinery, this UPS is the answer.
Usages
The tower fits in a server room and protects up to 20 kVA of load. Use it to keep IT racks running, to safeguard industrial control panels, or to power medical imaging devices that require a stable sine wave. It also works well for large-scale CCTV systems, broadcast equipment, and any three-phase setup that cannot tolerate voltage distortion.
