Designed and built by Legend, the Voltage Logger will measure and record your building’s voltage level, which will help determine how much energy you can save through onsite voltage optimization.

The standards allow for a range of voltage between + - 5% (126V – 114V) at building level but for electrical appliances, machines, lighting, etc. to operate efficiently and reduce unnecessary wear and tear, they typically have prescribed nominal voltages. This is often an area with potential for energy savings.
