What is the typical voltage range used for elevator control circuits?

The typical voltage range used for elevator control circuits is indeed found within the 12 to 24 volts DC range. This lower voltage is commonly used for control functions to ensure safety and reduce the risk of electrical shock to personnel who may be performing maintenance on the elevator system.

Elevator control circuits operate at lower voltages because they are designed to control various components such as relays, contactors, and sensors, which require less power and are more sensitive. Using lower voltages is part of standard safety practices in elevator installations, helping to safeguard both operators and service personnel.

While other voltage ranges may be applicable in different contexts within the electrical systems of buildings, they are not typical for the control circuits specifically associated with elevator operations. Higher voltages, like those in the options presented, are generally used for power supply to the motor and other heavy-duty components rather than for control circuits.
