Model list (Gen2)

Part number	Model	Capacity (VA/W)	Input	Output
9210-53050	5PX 1000i RT2U G2	1000/1000	IEC C14 (10A)	8 × C13 (10A)
9210-63060	5PX 1500i RT2U G2	1500/1500	IEC C14 (10A)	8 × C13 (10A)
9210-73037	5PX 2200i RT3U G2	2200/2200	IEC C20 (16A)	8 × C13 + 2 × C19
9210-73043	5PX 2200i RT2U G2	2200/2200	IEC C20 (16A)	8 × C13 + 2 × C19
9210-83121	5PX 3000i RT3U G2	3000/3000	IEC C20 (16A)	8 × C13 + 2 × C19
9210-83120	5PX 3000i RT2U G2	3000/3000	IEC C20 (16A)	8 × C13 + 2 × C19

RT2U and RT3U refer to 2U and 3U chassis heights — same capacity, but the 3U body has more internal room and airflow. Power factor is 1.0 (VA = W), so the real driving capability is honest.

Who this suits

The 5PX is the "good enough, done properly" answer. For servers, network gear, POS or surveillance on a normal site supply, the line-interactive architecture is efficient, runs cool and is priced fairly.

Move up to the 9PX online range if any of these apply: frequent sags or brownouts on the supply; waveform-sensitive equipment (precision instruments, medical); or a requirement for output fully isolated from the mains.

Why "pure sine wave" matters

Cheap UPS units often output a simulated (stepped) sine wave. That is tolerable for transformer-based supplies — and problematic for active PFC supplies, which nearly all current servers and switches use: audible noise, extra heat, sometimes a failure to transfer to battery at all. This is the most overlooked — and most expensive — mistake in UPS buying.

Key features

Line-interactive with built-in automatic voltage regulation (AVR) — mains sags and surges are corrected without draining the battery

Pure sine wave output, safe for servers and network gear with active PFC supplies

Rack or tower out of the box — rack brackets included

Expandable battery module extends runtime without replacing the unit

USB and serial ports with power-management software for automatic shutdown

Optional network management card brings the UPS into your existing monitoring

Where it fits

SME machine room

A switch plus a few servers — 5PX covers it without buying a three-phase frame for a small load.

Shops and offices

Short-ride-through backup for POS, tills and network gear, so a trip does not interrupt a sale.

Surveillance and access control

Recorders and door controllers stay up through an outage, keeping footage and access running.

Frequently asked questions

How does line-interactive differ from online — which do I need?

Line-interactive passes mains through and corrects voltage with an AVR — efficient, cool-running and affordable. Online double-conversion regenerates the output entirely, isolating the load from the mains. Offices, shops and small machine rooms are well served by a 5PX; step up to the 9PX if the equipment is sensitive or the grid is poor.

How long will it run?

Runtime is not a property of the unit alone — it is load power against battery capacity. The same 5PX may hold a 300 W load for 15 minutes and a 1,000 W load for about 4. Send us the equipment list and we will calculate it for your case.

When do the batteries need replacing?

Typically every 3–5 years, sooner in hot rooms. An annual discharge test shows the real state — replace the set when runtime drops noticeably, rather than block by block.
