Which power source is described as being powered by two 12VDC rechargeable batteries?

• A. Hydraulic Power Source
• B. Electrical Conduit
• C. Hoistway Dimensions
• D. Weight of Units

Answer: (A)

The main idea is that a hydraulic power source can be driven by DC power from batteries. In this setup, two 12V DC rechargeable batteries are used to supply the hydraulic pump, typically by wiring them in series to provide a higher, 24V DC supply. This allows the hydraulic drive to operate independently of the main AC power, which is useful for emergencies or service where a self-contained power source is advantageous. The other options aren’t power sources at all: electrical conduit is just a path for wiring; hoistway dimensions and weight of units describe physical characteristics, not power sources.
