Industry solutions
Two sites with the same power consumption can need completely different backup — it depends on the load profile and what an outage actually costs you.
Data centres and server rooms
A power cut in a server room does not cost you a few minutes of downtime — it costs corrupted data, interrupted services and customers. Backup power has to be right on three counts at once: capacity, redundancy and runtime.
Schools and education institutions
A campus protects more than its servers. Backup power here has to hold administration and teaching systems together, keep the safety and communication equipment alive, and still be safe around students.
Law firms, accountancy practices and financial institutions
For a financial or professional services firm, a power cut is not just downtime. It is a broken transaction, a corrupted file, and a compliance question you may have to answer long after the lights come back on.
Industrial production lines and manufacturing
One second of lost power on a production line can cost a whole batch of work in progress. On a factory floor, backup power is really about inrush current and voltage quality, not just capacity.
Logistics, warehousing and marine
Backup power in a warehouse or a marine environment has three demands an office never raises — vibration, humidity and corrosion — and often no stable mains supply to fall back on.
Clinics and medical institutions
In a medical setting a power cut is not an inconvenience, it is a risk. An interrupted treatment, an imaging unit that shuts down mid-scan and a records system that drops are clinical and legal problems, not IT ones.
NGOs, charities and places of worship
The budget is tight, but what matters still has to be protected. Here the whole job is telling "cannot stop" apart from "can wait", and spending only where it counts.
Commercial buildings, malls and retail property
When the power goes, the first systems you cannot afford to lose are often access control, CCTV and the tills. Lose those and security and revenue fail at the same time.
Project case studies
Delivered installations across Hong Kong. Each one started from a constraint — rack space, runtime, inrush current or a hostile environment — and the configuration followed from it.
CCTV control room UPS with lithium batteries
A control room is the most power-sensitive part of any CCTV system: lose the mains and recording and access control fail together. We fitted a UPS and lithium battery pack to keep the console and its core equipment running.
Vehicle-mounted lithium battery UPS
A communications vehicle often works where there is no mains supply at all. Its on-board UPS has to cope with vibration and heat, and the lithium option keeps the vehicle weight down.
EATON 15 kVA UPS installation
A straightforward-looking UPS installation is usually anything but, and here the site distribution was the real work. The unit went in with new breakers, earthing and a full set of test records.
EATON tower UPS installation, Hong Kong commercial office
A compact EATON tower UPS installed in a tight corner of a Hong Kong commercial office, commissioned on load and left protecting the office equipment through mains disturbances.
Enterprise server room EATON UPS
An EATON UPS selected around the room's real load and distribution, balancing power quality today against a stable supply of spares and batteries for the years ahead.
Hospital lithium battery UPS
Medical sites have the highest demand for continuity of supply, and add their own requirements for clean, low-maintenance batteries. We provided lithium UPS backup for the critical equipment on site.
Knowledge base
How the decisions are actually made: sizing, battery life, installation and fault diagnosis — written so you can judge a quotation on its merits.
UPS troubleshooting: what you can check, what needs an engineer
When a UPS starts alarming, do not reach for the plug first. Reading what the panel is telling you is enough to judge whether it is something to watch — or something to deal with tonight.
What is a UPS? The three architectures explained
Most buyers ask only two questions — how much, and how many watts. But two machines both labelled 1000 VA can protect your equipment very differently, and the difference comes down to architecture.
When should UPS batteries be replaced? Three measurements decide
A UPS that drops the load the moment the mains fails is almost always a battery problem, not a dead unit. Whether to replace is not a question of how many years old the battery is — it is a question of three measurements.
Five installation essentials — miss one and it fails
Installing a UPS is not a matter of finding a socket. Get any one of these five points wrong and the result ranges from nuisance alarms and shutdowns to damaged equipment and a safety hazard left behind.
What size UPS do I need? Sizing capacity and runtime
My equipment adds up to 2000 W, so is a 2000 VA UPS enough? That calculation almost always ends in the wrong purchase. What is missing is not addition — it is three correction factors.
Whether you run a small server room, a clinic that cannot afford a single minute of downtime, or a production line where an outage means scrap and rework — we make sure the lights (and the servers) stay on when the mains do not.
What we do, in one line: we take care of your backup power from survey to design, supply, installation, maintenance and battery replacement.
- We supply and install UPS from major brands — EATON is our primary brand — selected to fit your load and runtime, not to clear stock.
- We repair and maintain UPS of most brands, including systems we did not originally supply.
- Through our own production base in Shenzhen we build lithium-battery UPS, rack-mount inverters and LiFePO4 battery packs under our own brand THTAK — customisable in capacity, voltage and cabinet size.
Every job starts with a free on-site survey: our engineer measures your actual load, checks your distribution board and generator (if any), and only then proposes a configuration. You get a clear quote before anything is ordered.
If you already have a UPS that misbehaves, or batteries that are past their service life, start with our services or message us on WhatsApp — we respond quickly and work across all of Hong Kong.
Already know the model you need? Our full model list covers every series we supply, and can be searched by model number — then ask us for an English quotation.
