During a power failure at Guangzhou International Trade Center last year, our 60kVA UPS kept 8 elevators operational, safely evacuating 127 people within 15 minutes.
An elevator UPS provides:
- Continuous power during outages (15-90 minute runtime)
- Clean electricity for sensitive control systems
- Safe passenger evacuation capabilities
- Protection from power surges and spikes
- Automatic failover within milliseconds
What is Emergency Backup Power Systems for Elevators?
We've installed over 300 emergency power systems across Asia, learning exactly what makes them effective during real failures.
Critical system components:
- High-capacity UPS (30-150kVA)
- AGM or lithium battery banks
- Automatic transfer switches
- Voltage regulation systems
- Remote monitoring capability
Emergency Power System Specifications
| Component | Residential Buildings | Commercial Towers | Hospital Facilities |
|---|---|---|---|
| Runtime | 15-30 minutes | 30-60 minutes | 60-90 minutes |
| Battery Type | AGM (5-7 year life) | AGM/Lithium | Lithium (10+ year) |
| Transfer Time | <10ms | <8ms | <5ms |
| Redundancy | Optional | Recommended | Required |
Regulatory Note: Most jurisdictions mandate minimum 30-minute backup for commercial elevators.
What are Backup Power Requirements for Elevators?
After analyzing power consumption patterns from 47 elevator models, we developed these key specifications.
Non-negotiable requirements:
- Must handle 3× rated current during startup
- Voltage regulation within ±5%
- Minimum THD <3%
- Seamless transition <10ms
Power Requirement Comparison
| Elevator Type | Running Power | Startup Surge | Backup Duration | Our Solution |
|---|---|---|---|---|
| Hydraulic | 7-15kW | 21-45kW | 15-30 min | UPSE-H series |
| Geared Traction | 15-35kW | 45-105kW | 30-45 min | UPSE-G series |
| Gearless | 25-75kW | 75-225kW | 30-60 min | UPSE-T series |
| Machine Room-Less | 10-30kW | 30-90kW | 20-40 min | UPSE-M series |
Installation Tip: Always measure actual current draw before UPS sizing.
