Structure of an elevator control panel consists of following components: Control Board (Main Board), Drive (Inverter), Power Supply, Relays, Contactors, Fuses, Circuit Breakers, Terminals and Cable Connections: Terminals, Buttons and Indicators, Car and Landing Call Boards, Encoder and Sensor Input Boards, Communication Boards. As a specialized supplier of elevator spare parts and solutions, Sell-Best provides a comprehensive range of high-performance components that meet the requirements of modern vertical transportation systems. Below is an overview of the key control panel elements that Sell-Best can supply.
Elevator Power Supply
The power supply is the foundation of stable elevator operation. Sell-Best offers switch-mode power supplies (SMPS), regulated DC power supplies, and UPS backup solutions specifically designed for elevator applications. These units ensure consistent voltage output, protect sensitive microcontrollers and communication boards from transient surges, and maintain uninterrupted system operation during power fluctuations. Their compact design and high conversion efficiency also reduce panel space requirements and improve overall energy efficiency.
Elevator Contactors
Contactors serve as the switching devices for controlling elevator motors, door drives, and auxiliary safety circuits. Sell-Best’s AC contactors are designed with enhanced arc suppression, long electrical endurance, and compliance with IEC and EN standards.
Their robust construction ensures reliable performance under high inrush currents and frequent switching cycles, which are typical in elevator drive systems. This reliability contributes directly to safe motor start, braking, and directional changes in daily elevator operation.
Elevator Encoders
Position and speed control are essential for smooth and accurate elevator movement. Sell-Best provides incremental and absolute encoders with high resolution and durable bearings, optimized for elevator drive feedback systems.
These encoders enable precise floor leveling, consistent acceleration and deceleration profiles, and reduced vibration during travel. By providing stable signal output even under mechanical stress and vibration, they improve ride comfort while minimizing wear on the traction system.
Elevator Inverters / VFDs / Drives
At the heart of motor control, Variable Frequency Drives (VFDs) regulate elevator speed, torque, and direction. Sell-Best supplies elevator inverters engineered with advanced vector control algorithms, high overload capacity, and built-in protection features such as overvoltage, overcurrent, and thermal monitoring. These drives not only optimize energy consumption but also reduce operational noise and extend motor lifespan.
With compatibility across residential, commercial, and high-rise applications, Sell-Best VFDs deliver precise motion control and improved energy efficiency in demanding elevator systems.
By integrating Sell-Best’s power supplies, contactors, encoders, and inverters, elevator control panels achieve greater reliability, safety, and efficiency. Each component is manufactured to international standards and designed to withstand the rigorous operational environment of modern elevators. For system integrators and service companies, Sell-Best provides not just spare parts, but a complete solution to enhance elevator performance and long-term dependability.
