EATON 5P line-interactive UPS (650–1550 VA)

The most compact line-interactive unit Eaton makes: pure sine wave output, ABM battery charging, tower or 1U rack — the sensible starting point for a workstation or a network cabinet.

Product details Specifications

Where the 5P sits

The 5P is the smaller sibling of the 5PX: same line-interactive architecture and pure sine wave output, in a more compact body and without the expandable battery module. For a single workstation, a wall-mounted network cabinet or a POS counter, it is usually the right size — and the 1U rack models fit a shallow cabinet that a 2U unit will not.

Two details worth checking before ordering

Outlet type. IEC C13 outlets on most models — confirm your equipment leads, or plan the adapters at order time.
Rack depth. The 1U models are shallower than most; measure the cabinet before assuming any 1U unit fits.

Sizing is free before quotation — send us the load list and we will confirm the right capacity.

Selectable output 200/208/220/230/240 V, 50/60 Hz auto-sensing

Frequently asked questions

How is the 5P different from the 5PX?

The 5P is the compact line-interactive unit — smaller, lighter, and cheaper, without the 5PX's expandable battery module and higher capacity ceiling. For a workstation or a wall-mount network cabinet the 5P is usually the right size; for a small machine room, step up to the 5PX.

What does ABM charging do for me?

ABM (Advanced Battery Management) charges in three stages and compensates for temperature, so the batteries are not held at float voltage unnecessarily. Eaton rates it at roughly 50% longer battery life — which in practice means one replacement cycle instead of two.

What size UPS do I need? Sizing capacity and runtime

My equipment adds up to 2000 W, so is a 2000 VA UPS enough? That calculation almost always ends in the wrong purchase. What is missing is not addition — it is three correction factors.
