Product overview

Ultra-compact professional UPS for a server rack: line-interactive with voltage regulation, 850 VA / 600 W, in a 1U rack form factor.
Technology & protection: it switches to battery the instant the power cuts out, absorbs surges and continuously corrects voltage fluctuations without drawing on the battery.
Power: 850 VA for 600 W of usable output.
Outlets: 4 C13 outlets (for computer and server power cords).
Pure sine wave output; the 1U form factor saves rack space. Quiet operation (below 40 dB).
LCD display: it shows the load, battery level and remaining runtime at a glance — so you can monitor the UPS without any software.
Ideal, for example, for a rack-mounted switch, firewall or small server.
Remember to check how much power your equipment draws and to choose the capacity according to the runtime you need.

Frequently asked questions about this product

An 850 VA UPS in 1U — is that really possible?
Yes: the 5P 850i fits in 1U — 43.2 mm high — with a width of 438 mm, a depth of 509 mm and a weight of 13.8 kg. That is half the height of a conventional rack-mount UPS, but the depth still needs checking.
How long does the 5P 850i run on battery?
12 minutes at half load and 7 minutes at 70%. With 600 W of usable power, that is enough to shut down a switch, a router and a small rack server cleanly.
Is the output of the 5P 850i a pure sine wave?
Yes, the output waveform is a pure sine wave — it is stated explicitly, and rare on a line-interactive UPS of this size. The signal stays clean even when the UPS switches to battery.
What voltage and frequency range does the 5P 850i accept?
From 160 to 294 V, adjustable down to 150 V, and from 47 to 70 Hz on a 50 Hz system — down to 40 Hz in low-sensitivity mode. This last setting allows it to cope with a very unstable power source.
Why does 850 VA only give 600 W?
The power factor is 0.7: 850 × 0.7 ≈ 600 W actually available. Compare this figure in watts with the combined power draw of what you install in the rack, not the VA in the product name.
What is in the 5P 850i's box?
The rack-mounting kit, a cable locking system, a USB cable, a serial cable, two IEC-IEC cords, the quick start guide and the safety instructions. Nothing extra to order to install it.
Can the batteries be changed without cutting the power?
Yes, they are hot-swappable. The UPS contains two sealed 12 V / 7 Ah lead-acid batteries, and an audible alarm signals changes of state.
Can the USB port and the serial port be used at the same time?
No, the two do not work simultaneously. The UPS also has contact terminals, a remote on/off mini-connector and a slot for a Network-MS, ModBus-MS or Relay-MS card.
Is the Eaton 5P 850i Rack 1U new and under warranty?
Yes, new equipment, with the invoice serving as the warranty document, for 3 years. It has four C13 outlets with a C14 inlet, stays below 40 dBA, and its output voltage can be set to 200, 208, 220, 230 or 240 V. The datasheet covers the rest.
