Benefits include: Wirelessly control on ON/OFF functions of ALL landscape lighting. Schedule ON/OFF functions and create custom scenes.
Q: What is a low voltage transformer?
A: Low Voltage Transformers . Low voltage transformers are power transformers that are used to change the voltage capacity of a low-voltage electrical transmission line. Typically, electronic low voltage transformers convert 120 volts into 12 volts or 24 volts.
Q: What is a 24 volt power supply?
A: The 24 Volt Power Supply is a outgrowth of the 12V common battery voltage. A 24 Volt supply provides more available power for a moderate increase in size. With the advent of solid state equipment the move to more powerful consumer devices for use in home and office required more powerful supplies.
