Low voltage photo control

Web21 feb. 2024 · This allows energy from the transformer to flow through the control circuit and it switches to low voltage lighting. In most cases, you will be able to place a photocell unit on top of the fixture’s current illumination switch. A photocell unit is a small box with a switch attached to your outdoor fixtures. WebA common rule of thumb is that anything below 600 volts is considered low voltage. Factories that use automation can use multiple voltages. Dividing the electrical use into supply and controls aids in understanding the usage. Each division performs a mission critical to the operation to the factory. Both must be working for production.
