APC Smart-UPS RT 6kVA 6kW Rack Tower 4U 230V On-Line Double Conversion
PRODUCT DESCRIPTION
APC Smart-UPS RT 6kVA 230V International (SRTG6KXLI) - 2 Years Local Warranty
6 kVA / 6 kW Double-Conversion On-Line UPS for the Singapore Server Room
The APC Smart-UPS On-Line SRTG6KXLI is a 6,000 VA / 6,000 W double-conversion UPS from the Smart-UPS RT (SRTG) generation, sized for a server room that has outgrown a 5 kVA unit but does not yet justify the 5U chassis. Incoming mains is rectified to DC and regenerated as a clean sine wave, so the load is fed from the inverter continuously rather than switched across when the supply fails. Output voltage distortion is rated at less than 2%, and an internal automatic and manual bypass carries the load if the inverter is overloaded or taken out for service. On a Singapore riser shared with lifts and chillers, that continuous regeneration is what keeps sags and switching transients away from your servers.
Unity Power Factor, 230 V Single-Phase In and Out
The SRTG6KXLI is a unity power factor design: it delivers the full 6,000 W from its 6,000 VA rating, so you size on real watts with nothing lost to a 0.8 or 0.9 multiplier. Input is 230 V single-phase (220 / 230 / 240 V user-selectable), hard wired through a 3-wire (1P + N + E) terminal block, with a wide 160–285 V window at full load and 100–285 V at half load before the unit has to fall back on its batteries. Output is 230 V at 50/60 Hz ±4 Hz synchronised to mains (±0.1 Hz on battery), on two IEC C13 outlets, one IEC C19 outlet and a hard-wire 3-wire terminal block. Maximum input current is 33 A and full-load output current is 28 A. Unlike the 15 and 20 kVA units in the range, the 5–10 kVA SRTG models are single-phase only — there is no 400 V three-phase input option.
Batteries on a ±96 V Bus, Scalable with the SRTG192XLBP4 Pack
Internal batteries are sealed maintenance-free VRLA, 16 x 12 V 5 Ah cells in two battery modules on a ±96 VDC bus, with the APCRBC170 as the replacement cartridge (quantity 1) and a typical recharge time of 4 hours. Schneider's Smart-UPS RT 5–20 kVA range brochure lists approximately 2 minutes at the full 6,000 W and 8 minutes at half load (3,000 W) — a ride-through figure, not autonomy. For generator start-up cover or a multi-server shutdown window, add up to four SRTG192XLBP4 external packs, the 192 V, 5 Ah, 3U pack built for the SRTG 5–10 kVA models. Expected battery life is three to five years; plant-room temperature decides which end you get.
4U Rack or Tower — and the Rail Kit Is Not Included
The SRTG6KXLI is rack / tower convertible in a 175 mm (H) x 440 mm (W) x 620 mm (D) chassis, occupying 4U when racked. At 620 mm deep it fits a standard 1,000 mm server cabinet with room for cabling, and the stabiliser brackets for tower use are in the carton. The rail kit is not included: order SRTGRK1 for the UPS (Schneider's product page lists the same kit for the SRTG192XLBP4 pack). Net weight is 55.9 kg (61.8 kg packaged), so plan a two-person lift and mount it low in the cabinet. Acoustic noise is rated at 55 dBA, quiet enough for a comms room that shares a wall with an office.
Network Management Card 3 Pre-Installed, Colour LCD, Green Mode, Local Singapore Supply
An AP9641 Network Management Card 3 with environmental monitoring is pre-installed, with a one-year Secure NMC subscription per Schneider's listing, so SNMP, HTTPS and PowerChute Network Shutdown work the day it is racked. Local interfaces are serial (RJ45), USB Type B, an EPO terminal with normally-closed contacts, a maintenance-bypass signal (MBS) input and a battery temperature sensor terminal. The multi-colour LCD scrolls input, output, load, battery temperature and charge, runtime and ambient temperature. Green (ECO) mode feeds the load directly from mains at up to 98% efficiency and, per Schneider's manual, returns to inverter or battery within 8 ms of a mains failure; a Generator Mode setting relaxes input sensitivity for sites on standby generators. SourceIT supplies the SRTG6KXLI from Singapore with a GST invoice and local warranty support.

Compatibility & Runtime
What you can connect. Output is delivered on (2) IEC C13, (1) IEC C19 and (1) hard wire 3-wire (1P + N + E) terminal block, the IEC outlets forming two controllable groups on 16 A and 10 A circuits. In practice the IEC outlets feed a rack PDU or top-of-rack devices, and the bulk of the load is wired out through the terminal block. Total the real power draw (watts) of everything you intend to protect and keep it below 6,000 W with headroom.
Runtime at stated loads. Schneider's Smart-UPS RT 5–20 kVA range brochure lists approximately 2 minutes at the full 6,000 W and 8 minutes at half load (3,000 W). Runtime is not linear — halving the load more than doubles the time on battery. Recharge time is 4 hours. Ask SourceIT for a runtime calculation against your measured load.
Extended runtime. Connect up to four SRTG192XLBP4 packs in parallel. Each pack is 192 V (±96 V), 5 Ah, 3U, 83.5 kg, and ships with its battery cable and brackets but not the rail kit. The SRTG192XLBP2 is the ±192 V, 9 Ah pack for the 15 and 20 kVA units and does not fit this UPS.
Rack fit. 4U when racked, in a 175 mm (H) x 440 mm (W) x 620 mm (D) chassis, rack / tower convertible. The rail kit is not included — order SRTGRK1. Each SRTG192XLBP4 pack adds 3U and 83.5 kg, so a UPS with two packs is 10U and roughly 223 kg: check the cabinet's static load rating and mount everything at the bottom. A 600 mm comms cabinet is not deep enough for the 620 mm chassis plus cabling.
Input and circuit — read this before ordering. The SRTG6KXLI is hard wired on the input: a 3-wire (1P + N + E) terminal block, no plug, maximum input current 33 A on a 230 V single-phase supply. A licensed electrician must size and terminate the feeder. For a three-phase input, see the SRTG15KXLI or SRTG20KXLI.
Package Contents & Smart-UPS RT (SRTG) Ordering Information
In the box (per Schneider's installation manual): front bezel, RJ45-to-DB9 serial cable, USB cable, one IEC C13/C14 10 A 1.5 m lead and one IEC C19/C20 lead, hard-wire terminals, M5 floating nuts and screws, M4 x 6 flat-head screws, rack-mount brackets, two pairs of stabiliser brackets with connectors, installation manual and packing list. The AP9641 Network Management Card 3 is pre-installed; the rail kit is not included. The two IEC leads are output jumper leads, not input cords — the input is hard wired, so there is no Schuko plug to worry about.

Frequently Asked Questions — APC SRTG6KXLI
What is the difference between the 6,000 VA and 6,000 W rating, and how do I size the SRTG6KXLI?
VA is apparent power and W is real power. On many UPS families the watt figure is lower and watts is what limits you — but the SRTG6KXLI 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 with headroom.
How long will the SRTG6KXLI run on battery?
Schneider's Smart-UPS RT 5–20 kVA range brochure lists approximately 2 minutes at the full 6,000 W and 8 minutes at half load (3,000 W). That is deliberately short — a UPS at this capacity is sized to ride through a dip and cover a generator start or an orderly shutdown. For longer autonomy add SRTG192XLBP4 packs, up to four. Recharge time is 4 hours.
Can the SRTG6KXLI take a three-phase supply?
No. The 5, 6, 8 and 10 kVA SRTG models are single-phase only: 230 V in (220 / 230 / 240 V selectable), 230 V out, hard wired through a 3-wire (1P + N + E) terminal block. For a 400 V three-phase input or 3:1 operation, look at the SRTG15KXLI and SRTG20KXLI.
Does the SRTG6KXLI produce a sine wave output, and will it work with an active-PFC power supply?
Yes. It is an on-line double-conversion design with a sine wave output rated at less than 2% voltage distortion, so the load is fed from the inverter continuously. That is the output type active-PFC server and storage power supplies expect.
Which replacement battery does the SRTG6KXLI take?
The APCRBC170, quantity 1. The internal batteries are sealed maintenance-free VRLA, 16 x 12 V 5 Ah cells in two battery modules on a ±96 VDC bus. This is a different cartridge from the APCRBC140 used across the older SRT 5–10 kVA range and the APCRBC172 in the SRTG 15 and 20 kVA units — do not order by analogy. Expected service life is three to five years.
Which external battery pack fits, and how many can I add?
The SRTG192XLBP4 — 192 V (±96 V), 5 Ah, 3U, 83.5 kg — and you can connect up to four in parallel. The SRTG192XLBP2 is a different product for the 15 and 20 kVA units (±192 V, 9 Ah, 4U, 116 kg) and does not connect to this UPS. Each XLBP4 pack ships with its battery cable and mounting brackets but not the rail kit.
How does the SRTG6KXLI compare with the SRTG5KXLI?
Same 4U chassis, 55.9 kg, sixteen-cell battery set, APCRBC170 cartridge and pre-installed management card. This unit carries 6 kW instead of the SRTG5KXLI's 5 kW on the same battery, so its published full-load runtime is shorter (approximately 2 minutes against 3) and its maximum input current is 33 A against 28 A. Under 5,000 W measured load the SRTG5KXLI gives more minutes on battery; above it, or with growth expected, this is the one. For 8 kW and above, the 5U SRTG8KXLI and SRTG10KXLI double the battery complement.
Is the SRTG6KXLI covered by warranty in Singapore?
Yes. Every APC SRTG6KXLI sold by SourceIT comes with local Singapore warranty and a GST invoice; APC backs the SRTG6KXLI with a 3-year manufacturer warranty on the UPS (excluding the battery) and 2 years on the battery.
