What is the control cabinet in an elevator?
An elevator control cabinet is an electrical control device housed in a cabinet structure that provides safety protection. It is used to control the operation of the elevator and serves as the electrical and signal control center of the elevator. The main functions of the elevator control cabinet are operational controlling and drive controlling. Generally, it is placed in the elevator machine room, but for machine-room-less elevators, the control cabinet is installed in the shaft.

The main components in an elevator control cabinet include elevator control boards or controllers, transformers, bridge rectifiers and capacitors, air switches or fuses, relays and contactors, frequency inverters, power cables, signal cables, terminals, or connectors. Traditional elevator control boards mainly use PLCs (Programmable Logic Controllers), which function as microcomputers. However, modern elevators primarily adopt integrated controller cabinets, which dominate the market. These cabinets offer several advantages: They present a delicate and refined appearance, provide versatile installation options, and naturally integrate with architectural and interior design styles. The integrated design achieves deep integration, reducing the control cabinet’s volume to only 30% of traditional control cabinets.
Home Villas Elevator Control Cabinet Installation Principles
The noise from the control cabinet of a home elevator mainly originates from the operation of the elevator and the engagement of various contactors. If the control cabinet is positioned too close to a room, it may cause elevator noise. For villas with a dedicated equipment room, homeowners can place the control cabinet in the equipment room, but they should ideally ensure it is within 10 meters of the shaft. Keeping the control cabinet about 5 meters away from the main machine helps avoid affecting signal transmission.
Some people might also worry about whether the control cabinet of a home elevator emits radiation and if it is harmful to humans. The control cabinet primarily emits electromagnetic radiation. Most control cabinets emit some level of radiation, but the metal casing shields most electromagnetic waves and grounds them, preventing harm to humans. The radiation level is generally smaller than that of a mobile phone, so people do not need to worry.
