UPS for Elevator

Asansörler modern yaşamın en kritik bileşenlerinden biridir. Apartmanlardan iş merkezlerine, hastanelerden otellere kadar her yapıda asansörler hem konfor hem de zorunlu ulaşım ihtiyacını karşılar. Bu kadar önemli bir sistemin elektrik kesintilerinde durması, yalnızca ulaşımın aksaması anlamına gelmez; aynı zamanda ciddi güvenlik risklerine yol açabilir. Asansör içinde kalan kişilerin mahsur kalması, ani durmalardan kaynaklanan arızalar ve kontrol ünitelerinin zarar görmesi en sık karşılaşılan problemlerdendir. Bu nedenle “Asansör İçin UPS” kullanımı günümüzde bir seçenek değil, yasal gereklilikleri destekleyen bir **zorunluluktur**.

UPS (Uninterruptible Power Supply) kicks in the moment the power goes out, ensuring the elevator safely moves to the nearest floor and the doors open. It also regulates power fluctuations, preventing damage to the electronic control panel. Elevators have high-power motors, so the UPS used must be more powerful, more stable, and compatible with the motor load than standard UPS models.

Why is a UPS Necessary for Elevators?

An elevator suddenly stopping during a power outage is a panic-inducing and dangerous situation for those inside. Power outages in elevators without UPS systems pose the following risks:

• Passengers being trapped inside the cabin
• Failure to conduct an emergency evacuation
• Mechanical stress occurring in the cabin and engine group
• Damage to the elevator control board due to fluctuations
• Operational disruption in heavily used buildings

The UPS system eliminates all these risks. When the power goes out, the elevator moves to the most appropriate floor based on its operating speed, and the doors open automatically. This allows passengers to be safely evacuated.

How Does an Elevator UPS Work?

The elevator UPS regulates the electricity it receives from the grid under normal conditions and transmits it to the control system. It also charges its batteries. When the power goes out, it kicks in and provides the necessary energy to the motor driver. This allows the elevator to continue operating in safe mode without sudden stops.

The operating principle of UPS is as follows:

• When connected to the grid: Filters energy and charges the batteries.
• During a power outage: Switches to UPS mode within milliseconds.
• Directs the elevator to the safe floor: The motor slowly moves to that floor.
• Enables doors to open: Creates a safe environment for evacuation.

This seamless transition is essential to prevent injury to passengers and to protect elevator equipment.

Why Should Online UPS Be Used When Selecting an Elevator UPS?

Elevator systems have high-power motors and require a large current during initial startup. Additionally, modern elevators with inverter drives require stable and clean power for their electronic cards. Therefore, the UPS type used in elevators must definitely be an Online UPS.

Advantages of online UPS:

• Transfers power with zero interruption. (It is critical in emergencies.)
• It provides the cleanest energy with AC–DC–AC conversion.
• It can handle high starting currents.
• Fully compatible with motor loads and electronic drivers.
• Completely filters voltage fluctuations.

Due to these characteristics, line-interactive UPS models are inadequate for elevators; therefore, they should not be preferred.

Suitable UPS Capacity for Elevators (kVA Selection)

The most important criterion when selecting an elevator UPS is power capacity. The correct UPS selection should be made by considering the elevator’s motor power, load capacity, and motor driver.

Ideal UPS capacities according to general usage scenarios:

• 6 kVA Online UPS → Small elevators for 4–6 people, low-rise buildings
• 10 kVA Online UPS → Medium and large-scale elevators, multi-story buildings
• 3 kVA Online UPS → Backup for hydraulic door systems or small motorized freight elevators

UPS selection must be made more carefully in modern inverter-driven elevators. Therefore, load analysis should be performed by experts, and UPS with a capacity lower than the requirement should definitely not be preferred.

Advantages of Using Elevator UPS

UPS systems specially designed for elevators not only operate during power outages; they also extend device lifespan by improving grid quality.

Key advantages:

• It eliminates the risk of being trapped in the cabin.
• Ensures the elevator operates in safe mode.
• It significantly reduces electronic card and driver failures.
• It prevents operations from stopping in heavily used buildings.
• It reduces annual maintenance and repair costs.

An elevator system without a UPS poses a serious security risk, especially for hospitals, hotels, and high-rise buildings.

How to Install an Elevator UPS?

Elevator UPS installation requires expertise. An incorrectly selected or improperly connected UPS can damage equipment during operation. Therefore, UPS installation must be performed by technical personnel.

Installation steps:

• The elevator motor power and driver load analysis is performed.
• An online UPS with the appropriate kVA rating is determined.
• The connections between the UPS, motor driver, and control panel are established.
• The system is tested by performing an outage simulation.

After this test, the system will be ready to operate with full compatibility.

What to Consider When Choosing a UPS?

An elevator UPS is not an ordinary power supply. Models that are compatible with motorized loads, provide high power, and ensure zero interruption should be used.

The following criteria are important when making a selection:

• When choosing online UPS technology, the following criteria are important:
• Ability to handle starting current
• True kVA capacity
• Compatible with driver type
• Battery life and quality
• Professional installation guarantee
