A power cut or voltage dip lasting a few seconds can corrupt a database, freeze a point-of-sale terminal or knock a server offline, which is why offices, shops and server rooms in Singapore fit uninterruptible power supply units. Buying the box is only part of the job, because batteries wear out and larger systems need installation, testing and servicing. This guide gathers eight Singapore suppliers and service firms, from global manufacturers with local offices to specialist UPS houses and IT resellers. Each entry is described from the company's own website and attributed accordingly, with no prices quoted. Confirm brands, response arrangements and scope directly before you commit.

1. Rehlko (formerly Kohler Uninterruptible Power)

Rehlko, the name under which Kohler Uninterruptible Power now trades, runs a dedicated Singapore website for its UPS business. The site describes the company as a specialist in critical power protection, spanning uninterruptible power systems, batteries and standby generators. Its listed service categories include maintenance, repairs, battery services, monitoring, on-site work and equipment hire, alongside single-phase and three-phase UPS systems and battery solutions. It says support is available around the clock and names banking, data centres, healthcare, retail and government among the sectors it serves. That breadth suits larger server rooms and facilities wanting one party for hardware and upkeep, while a shop buying a single small unit may find a retail supplier simpler. Ask which UPS brands a service agreement covers.

2. Riello UPS Singapore

Riello UPS Singapore is the local subsidiary of the Italian manufacturer Riello UPS, and the group's own contacts page lists a Singapore office in the Chai Chee area. The group site describes single-phase and three-phase UPS ranges from small units suited to home offices up to large installations for industrial plants and data centres, plus software, connectivity and transfer systems. It also publishes a UPS services section and a customer support area. Singapore business registry listings describe the entity's activity as sale, installation and maintenance of uninterruptible power systems. Buying from a manufacturer's own subsidiary can simplify questions about spare parts and software, so ask which models the Singapore team supports and whether site surveys are offered before you commit.

3. Sowers (KG Sowers Group)

Sowers, the trading name of KG Sowers Group, is an IT infrastructure firm that devotes a page of its site to APC uninterruptible power supplies. The page lists five APC product families, from basic Back-UPS models for small offices to Smart-UPS On-Line units for data centres, and describes trade-in of older units, installation including electrical hardwiring, battery replacement and round-the-clock in-house maintenance support. It also advertises short-term UPS rental starting from a one-week hire. The company says it is an APC by Schneider Electric Premier Partner, a claim worth confirming with the manufacturer if authorisation matters to you. Its office is in the Nordcom II building, and the firm suits buyers who want power protection bundled with wider IT services.

4. CITEC International (SEA)

CITEC International (SEA) presents a Singapore UPS page aimed at server rooms and data centres, with its office in the Hudson TechnoCentre. The site lists tower and rack-mount models from the Ablerex and Kronos ranges across several capacity bands, plus a harmonic active filter and a battery monitoring system. It describes services including load assessment, N+1 redundancy design and lifecycle maintenance such as battery inspection and load testing. The firm says it has operated for more than two decades across Asia Pacific, a claim taken from its own page. Because its range leans towards engineered, higher-capacity installations, it may suit organisations planning redundancy or monitoring rather than someone replacing a desktop unit under a till. Ask about site surveys and maintenance scope.

5. Aflex Wheeltronics

Aflex Wheeltronics is a Singapore component trading and engineering company whose site includes a UPS section. It lists single-phase units from small capacities up to 10kVA and three-phase systems reaching into the hundreds of kVA, along with marine-grade variants, and names partner brands including Legrand, ELEN, Makelsan and GE Digital Energy. Its listed services cover maintenance packages, battery inspections, routine testing and fault diagnostics. The page also states bizSAFE Level 4 certification, which is relevant if your building requires contractors with workplace-safety credentials. The firm is based in the ARK@Gambas business park. As a broader engineering supplier rather than a pure UPS retailer, it may suit industrial or facility-led buyers; shops wanting a quick consumer unit may prefer a specialist reseller.

6. G-TEC Asia Pacific

G-TEC Asia Pacific describes itself as a Singapore-based specialist in the sale and service of UPS systems, stabilisers, frequency converters and industrial and stationary batteries, founded in 2004. Its site says the team includes factory-trained engineers and that most staff have more than three decades of UPS experience. Listed services include a dedicated call centre, on-site repair, commissioning and start-up, relocation of equipment, technical training and maintenance contracts ranging from periodic inspections to comprehensive cover. It also describes an optional remote monitoring package for its own UPS range. The company is based at Eunos TechPark II. Its focus on its own product lines means it may suit buyers wanting a single supplier for equipment and servicing, so ask whether your existing brand can be maintained.

7. SourceIT

SourceIT is a Singapore IT reseller near MacPherson MRT that sells APC uninterruptible power supplies and replacement batteries alongside workstations, headsets and video-conferencing gear. A blog post on its site sets out its case for genuine APC replacement battery cartridges over third-party alternatives and lists cartridge numbers with the UPS models each one fits, which helps when you are matching a part to an ageing unit. Treat the post as the company's own view rather than independent advice, and check how installation works. Because it is a general business IT supplier, it suits small offices and shops that want a like-for-like battery or a new desktop UPS from a local reseller rather than an engineered power project.

8. Win-Pro Consultancy

Win-Pro Consultancy is a Singapore and Malaysia IT support company that includes UPS supply and battery replacement among its services. Its site carries a UPS battery replacement page covering APC, Eaton, Liebert, MGE and Socomec units and compares original with generic compatible batteries, with a request form offering weekday, after-hours and weekend service windows. A separate page describes APC Smart-UPS On-Line models for servers and networks. The firm says on its site that it has traded since 1993, and its Singapore and Malaysia coverage may help multi-site businesses. It may appeal to small and mid-sized offices that already outsource IT support and want power protection handled by the same provider. Ask who performs the battery swap and how old cells are disposed of.

How to choose

Start with what the equipment protects and how long it must keep running. A shop till or small office router needs minutes of battery to shut down gracefully, while a server room may need extended runtime or redundancy. Give any supplier your connected load and desired runtime, and ask them to explain their sizing method.
Match the supplier to your existing brand. If you already own APC, Eaton, Riello or another make, ask whether the firm services that brand and can source genuine or compatible batteries. Ask whether its engineers are trained or authorised by the manufacturer, and request that claim in writing before relying on it.
Ask how batteries are handled. Sealed lead-acid cells in a UPS wear out over time and the replacement interval varies with load, temperature and unit size. Ask who installs them, whether old cells are collected for responsible disposal, and whether the supplier will test the unit after the swap rather than only fitting parts.
Understand what a maintenance agreement covers. Some contracts are periodic inspections only, while others include parts, labour and emergency call-outs. Ask for the scope, response arrangements outside office hours and what happens if a part must be ordered. Compare written quotations from at least two firms like for like.
Plan the installation as well as the purchase. Larger units may need hardwiring by a qualified electrician, adequate ventilation, floor space and a clear shutdown procedure. Ask whether a site survey is included, who handles building or landlord approvals, and whether monitoring software can alert you when the unit switches to battery.
