What is the voltage supplied to the control section of an escalator?

The voltage supplied to the control section of an escalator is commonly 24VAC. This lower voltage is used for safety and operational purposes, as it reduces the risk of electrical shock while still providing adequate power for the control systems that govern the escalator's operation. The control system includes components like relays, timers, and sensors, which require a lower voltage to function effectively without introducing the hazards associated with higher voltages.

Using 24VAC also allows for easier integration with various safety interlocks and monitoring devices, ensuring that the escalator operates within defined parameters and can respond to safety overrides or operational commands. This choice reflects industry standards that prioritize both safety and functionality in escalator design and installation.
