Start from the load and the site, not from a catalogue number. Each application page maps the load profile to a UPS, stabilizer, and battery configuration.
Each case shows the load, runtime, key configuration and engineering checks. They are typical industry configurations, not named customer projects; site photos are illustrative.

Reference project Tell us the kW, runtime, phase and site country. We will return a capacity, battery configuration and model sheet.
Protect the IT load with a modular or parallel frame, external battery, SNMP/DCIM monitoring, and a maintenance bypass.
3–20 kVA online UPS with rack or tower format, 10–60 minutes of runtime, and remote shutdown for branch IT.
Industrial UPS and three-phase AVR for PLC, DCS, CNC, water treatment, and process lines.
1–5 kVA UPS with 4–8 hours of runtime for NVRs, PoE cameras, access control, and alarm panels.
48 VDC rectifier systems and AC UPS for base stations, microwave links, and unmanned sites.
Three-phase AVR and UPS for hotels, offices, retail, lifts, HVAC controls, security, and payment systems.
SPD coordination for the service entrance, distribution board, UPS, and DC battery circuit.
kW, largest step, motor starting, and the load profile.
Generator start, outage duration, and the battery room.
Temperature, dust, altitude, phase balance, and documentation.
The same “UPS question” has different answers in a hospital, a bank branch, a hotel, a school, a telecom site and a factory. Fix the load priority and the runtime first; the model comes later.
Medical IT ICU, operating theatres, imaging, HIS, lifts and fire systems do not belong on one “hospital UPS”. Separate the medical IT load from the building load, and size the generator for the chillers, not only for the servers.
ATM A branch has two different backup targets: the teller and network load needs 30 minutes to close the day’s transactions, while the CCTV and access control need 4 hours. Split them, and keep the ATM on its own circuit.
PMS A hotel needs to keep check-in, payment, security, lifts and BMS alive; it does not need to run the chillers and the kitchen on a UPS. Put the AVR at the incoming supply and keep the critical-electronics UPS separate.
Campus A campus spreads its critical load across buildings: server room, exam rooms, labs, security, PA and network. A central AVR plus distributed rack UPS is usually more practical than one large UPS with long cable runs.
48 VDC Telecom sites are usually 48 VDC, unmanned and hot. The rectifier and battery carry the radio load; a small AC UPS covers the site’s AC loads. Runtime is set by the maintenance visit interval, not by the outage alone.
PLC A factory’s critical load is the control layer: PLC, DCS, CNC, robots, instrumentation and the line’s network. Motors, compressors and welders are generator and AVR loads. Mixing the two is how a UPS ends up oversized and underused.
These are typical industry profiles, not named customer projects. Site photos are illustrative; the final configuration follows the load list and site conditions.
For lifts, cold stores, pump stations, small offices and fuel stations, the critical load is not the whole machine. It is the controls, communications, payment, CCTV and alarms. Leave motors and compressors to the generator; the UPS carries only what cannot stop.
Rescue Elevator backup is a rescue function, not a ride-through for the motor. Size the UPS for the controller, communication and brake release, and confirm the rescue sequence with the lift supplier.
Controls Do not put refrigeration compressors on a UPS. Protect the controls, monitoring and alarm with a small UPS, correct the voltage with an AVR, and use a generator for the compressors.
VFD A pump station needs the controls, telemetry and valves on backup; the pump motor needs a generator, VFD or soft starter. A UPS sized for the motor is a costly mistake.
NAS A small office needs 15–30 minutes to save files and shut down cleanly. Put the router, NAS, PC and POS on a 1–3 kVA UPS; leave the laser printer and the air conditioner off it.
Dispenser A gas station needs the dispensers, POS, CCTV, tank monitor and lighting to survive a short outage. Keep the UPS outside the hazardous area, protect the supply with an SPD, and coordinate the shutdown with the fire system.
These are typical industry configurations, not named customer projects. Loads and runtimes are starting points for a project-specific calculation; the final selection follows the load list, site conditions and manufacturer data.
