How many volts does a typical automated sprinkler system use?

Explanation:
Low-voltage control powers sprinkler valves safely and efficiently. A typical automated sprinkler system uses 24 volts AC because the solenoid valves are designed for 24 VAC, allowing a controller to energize multiple zones from a single transformer with relatively small wiring. Using higher voltages (like 120, 240, or 277) would require heavier wiring, more complex safety measures, and isn't necessary for irrigation valve operation. The transformer steps down household or building power to this 24-volt level, balancing safety, cost, and practicality for running several valves across a landscape.
