Elevator systems demand clean, reliable power to guarantee smooth starts, safe stops, and precise control. Even minor voltage swings can trigger nuisance trips or accelerate wear on motors and electronics. A dedicated 3 phase voltage stabilizer for elevators, using servo voltage stabilizer technology, provides continuous voltage correction—shielding your elevator’s drive, control panels, and safety circuits from harmful fluctuations.
Advanced Features & Benefits
Broad Input Tolerance
Handles input voltages from 320 VAC to 480 VAC without tripping, keeping elevators running through brownouts and spikes.
Servo-Motor Regulation
Continuous, stepless mechanical tap changes deliver output accuracy of ±3–5%, ideal for heavy elevator loads and rugged environments.
Automatic Bypass & Protection
Built-in over-/under-voltage, overload, short-circuit, and over-temperature safeguards. If a fault occurs, an automatic bypass instantly reconnects mains power to maintain elevator operation.
Smart Monitoring
Integrated LCD panel displays real-time input/output voltages, load percentage, and fault codes.
High Efficiency & Durability
Up to 95% energy efficiency and robust mechanical design ensure long service life in challenging machine-room conditions.

Applications & Installation Guidelines
Ideal For: Passenger and freight elevators, escalators, and moving walkways.
Placement: Install near the elevator control cabinet in the machine room, ensuring at least 20 cm clearance for ventilation.
Cabling: Use appropriately sized three-phase cables rated for the stabilizer’s kVA. Include dedicated circuit breakers or fuses upstream and downstream.
Grounding: Securely bond the stabilizer chassis to the elevator room’s earthing grid to prevent electrical noise and enhance safety.
Maintenance: Every six months, clean fans and heat sinks, inspect servo-motor brushes and lubrication, and verify all terminal connections. Schedule a full functional test annually.
Summary
The TNS 3-phase servo voltage stabilizer delivers dependable, continuous voltage regulation—crucial for maintaining elevator uptime and passenger safety. With ±3–5% precision, rapid correction, and built-in bypass, it stands as a resilient solution for modern vertical transportation systems.
FAQ
Q1: Why is servo regulation preferred over static for elevators?
Servo stabilizers excel under heavy, fluctuating loads and offer robust mechanical isolation—ideal for elevator motors—even though their precision is ±3–5%. Static (electronic) stabilizers deliver tighter accuracy (±1–3%) but can be more sensitive to harsh electrical environments.
Q2: What happens if the stabilizer fails?
An automatic bypass immediately reroutes raw mains power to the elevator, preventing downtime. The fault is logged on the LCD and can be monitored remotely.
Q3: How do I size the stabilizer for my elevator?
Sum the peak motor start-up demand, control panel draw, and lighting load, then multiply by 1.2 (20% buffer). Choose a stabilizer with equal or greater kVA capacity.
Q4: What is the expected lifespan and support?
With proper maintenance, the TNS can operate reliably for over 10 years. It includes a 1-year standard warranty, extendable up to 5 years with optional service plans.
