APC Smart-UPS SRT 6000VA RM 230V
PRODUCT DESCRIPTION
APC Smart-UPS SRT 6000VA RM 230V (SRT6KRMXLI) - 2 Years Local Warranty
6 kVA / 6 kW Double-Conversion On-Line Protection in 4U of Rack Space
The APC Smart-UPS SRT 6000VA RM (SRT6KRMXLI) is an on-line, double-conversion UPS built for the 19-inch cabinet: incoming mains is rectified to DC and regenerated as a clean sine wave, so the load runs from the inverter continuously rather than being switched over when the supply fails. On Singapore's 230V / 50Hz supply that matters most during the afternoon storm season, when PUB grid dips and momentary interruptions are common enough to reset a server or corrupt a database write. Output voltage distortion is rated at less than 2%, and an internal bypass (automatic and manual) means an inverter fault does not have to mean a dropped load.
Unity Power Factor: 6,000 VA and a Full 6,000 W of Usable Output
The SRT6KRMXLI delivers 6,000 W from its 6,000 VA rating, so there is no watt derating to work around when sizing. Output is 230 V AC single phase (configurable to 220 V or 240 V) at 50/60 Hz ±3 Hz synchronised to mains, on (6) IEC 320 C13, (2) IEC jumpers and (4) IEC 320 C19 outlets plus a hard-wire output, with a 3:1 crest factor for switch-mode PSU inrush. Size on watts: total the real power draw of everything you intend to protect and keep it comfortably under 6,000 W.
4U of Rack Budget, Rail Kit Included
The SRT6KRMXLI occupies 4U in a 174 mm (H) x 432 mm (W) x 719 mm (D) chassis and ships with rack mounting support rails, brackets and hardware included, so budget the U space and check your cabinet depth — 719 mm is deep, and you need clearance behind the unit for the cable bend radius. Net weight is 60 kg, so mount it in the lower part of the cabinet and plan the lift with two people. If the deployment is free-standing rather than racked, the SRT6KXLI is the tower build of the same electronics.
Scalable Runtime with SRT192RMBP Battery Packs
Internal batteries are maintenance-free sealed lead-acid (VRLA) on a 192 V DC bus rated at 902 VAh, with a 597 W charger and a typical recharge time of 1.5 hours, and the replacement cartridge is the APCRBC140. Where you need longer autonomy the SRT6KRMXLI accepts up to ten SRT192RMBP external battery packs, taking the system from 2,706 VAh to 18,942 VAh. Schneider rates expected battery service life at three to five years; in a Singapore comms cabinet that is driven almost entirely by ambient temperature, so keep the room cool and dry. The unit is rated for 0–40°C at 0–95% non-condensing humidity.
Network Management Included, and Local Singapore Supply
Interface ports are RJ-45 10/100 Base-T, RJ-45 serial, USB and SmartSlot, a Web/SNMP management card is supplied with the unit, and one SmartSlot remains free for an AP9613 Dry Contact I/O card or an AP9641 with environmental monitoring. A multi-function LCD status and control console, prioritised audible and visible alarms, an emergency power off (EPO) connection and a temperature probe are all provided. Audible noise is 55 dBA and thermal dissipation 1,300 BTU/hr — budget both into a small comms room. SourceIT supplies the SRT6KRMXLI from Singapore with a GST invoice and local warranty support, so there is no overseas RMA and no import paperwork.

Compatibility & Runtime
What you can plug in. The SRT6KRMXLI provides (6) IEC 320 C13, (2) IEC jumpers and (4) IEC 320 C19 outlets, plus a hard-wire output. All outlets are battery-backed. Total the real power draw (watts) of the equipment you intend to protect and keep it below the 6,000 W rating — runtime falls sharply as load rises.
Runtime depends on load. Runtime is not linear: halving the load more than doubles the time on battery. Schneider publishes the internal capacity as 902 VAh with a 1.5-hour recharge time, but does not publish a runtime table for this model that we are able to cite, so rather than quote a figure we cannot source, ask SourceIT for a runtime calculation against your measured load.
Extended runtime. Connect up to ten SRT192RMBP external battery packs on the 192 V DC bus, taking total capacity from 2,706 VAh to 18,942 VAh. Recharge time increases with each pack added, and each pack has a keyed mating connector that only fits its corresponding UPS — APC does not support third-party packs. The tower SRT192BP is the pack for the tower SRT6KXLI.
Rack fit. Occupies 4U and ships with the rail kit included (rack mounting support rails, brackets and hardware). Chassis dimensions are 174 mm (H) x 432 mm (W) x 719 mm (D) — check cabinet depth carefully and allow for the cable bend radius behind the unit. At 60 kg, mount it in the lower part of the cabinet.
Input and circuit — read this before ordering. The SRT6KRMXLI is hard wired: hard wire 3-wire (1P + N + E). It does not arrive with a plug you can put into a wall socket — a licensed electrician must terminate it onto a suitably rated dedicated circuit. Confirm the supply arrangement and breaker rating with your electrician and building management before delivery. This is the single most common cause of a delayed SRT installation in Singapore.
Network management. Interface ports are RJ-45 10/100 Base-T, RJ-45 serial, USB and SmartSlot. A Web/SNMP management card is supplied with the unit and one SmartSlot remains free, so you can add an AP9613 Dry Contact I/O card, or an AP9640 / AP9641 Network Management Card 3 — the AP9641 adds environmental monitoring inputs for the AP9335TH sensor.

Frequently Asked Questions — APC SRT6KRMXLI
What is the difference between the 6,000 VA and 6,000 W rating, and how do I size the SRT6KRMXLI?
VA is apparent power and W is real power. On most UPS families the watt figure is lower than the VA figure, and watts is what limits you — but the SRT6KRMXLI is a unity power factor design, so it delivers the full 6,000 W. Add up the real draw of everything you want on battery and keep the total below 6,000 W. Sizing to about 70–80% of that leaves headroom for inrush and future additions, and gives noticeably longer runtime.
How long will the SRT6KRMXLI run on battery?
That depends entirely on load. Schneider publishes the internal capacity as 902 VAh with a 1.5-hour recharge time, but does not publish a runtime table for this model that we can cite, so we would rather give you a calculation than a marketing figure. For defined autonomy, add SRT192RMBP packs (up to 10, taking the system to 18,942 VAh) and ask SourceIT to size the configuration against your measured load.
Does the SRT6KRMXLI produce a sine wave output, and will it work with an active-PFC power supply?
Yes. Schneider specifies a sine wave output with less than 2% voltage distortion, and the unit is an on-line double-conversion design, so the load is fed from the inverter continuously. That is exactly the output type active-PFC server and workstation power supplies expect — unlike the step-approximated output of many entry-level line-interactive and standby UPS units.
What does the RMXLI suffix mean, and how is it different from XLI?
They are genuinely different builds. RMXLI is the rackmount orientation supplied with rack rails, brackets and mounting hardware; XLI is the tower orientation supplied without a rail kit and with removable support feet instead. The electronics, the 6,000 VA / 6,000 W rating and the outlet set are the same. Note also the separate SRT6KRMXLI-6W SKU, which carries a different registered warranty term — do not conflate the two on a tender.
Which replacement battery does the SRT6KRMXLI take, and can I change it myself?
It uses the APCRBC140 replacement battery cartridge, quantity 1. APC designs the SRT battery modules to be user-replaceable and the front bezel comes off without tools. Schneider rates expected battery life at three to five years; heat is the main determinant, so a cabinet that runs hot will shorten cartridge life.
How much rack space does the SRT6KRMXLI need, and is the rail kit included?
It occupies 4U in a standard 19-inch cabinet and the rail kit is included in the box, along with rack mounting brackets and hardware. Chassis dimensions are 174 mm (H) x 432 mm (W) x 719 mm (D) — check your cabinet depth, 719 mm is deep, and allow for cable bend radius behind the unit. Net weight is 60 kg, so mount it low in the rack and plan the lift.
Does the SRT6KRMXLI come with a plug?
No. The input is hard wire 3-wire (1P + N + E). A licensed electrician must terminate it onto a dedicated circuit of suitable rating. Factor that into your installation schedule and confirm the supply with building management before the unit is delivered.
Can I monitor the SRT6KRMXLI over the network?
Yes. Interface ports are RJ-45 10/100 Base-T, RJ-45 serial, USB and SmartSlot, and a Web/SNMP management card is supplied with the unit. One SmartSlot remains free if you want to add an AP9613 Dry Contact I/O card or an AP9641 Network Management Card 3 with environmental monitoring for the AP9335TH sensor.
How does the SRT6KRMXLI compare with the SRT5KRMXLI?
Both are on-line double-conversion Smart-UPS SRT rackmount units with rails included. The SRT5KRMXLI is rated 5,000 VA / 4,500 W in 3U; the SRT6KRMXLI is rated 6,000 VA / 6,000 W in 4U. The 6 kVA unit gives you 1,500 W more usable output for one extra U of rack space. If your load sits close to the boundary, take the larger unit — runtime and battery life both improve when a UPS is not run near its ceiling.
Is the SRT6KRMXLI covered by warranty in Singapore?
Yes. Every APC SRT6KRMXLI sold by SourceIT comes with local Singapore warranty and a GST invoice; APC backs the SRT6KRMXLI with a 3-year manufacturer warranty on the UPS (repair or replace, excluding the battery) and 2 years on the battery.
