Using cabling is expensive and a lure for copper thieves. With TABATEQs Elpro systems you can implement effective wireless load control within days.

Many electrical utilities need to ensure the electrical load is less than what can be generated in order to exercise some form of load control.

Certain applications are identified as “deferrable” as they can run after the peak, later in the day. Applications vary by region, but common loads include residential electric hot-water heaters, air conditioners, pool pumps, crop-irrigation pumps, etc.

Practicing load control requires communicating controllers that run programs to limit the duty cycle of the equipment.

TABATEQ's industrial wireless solutions

By means of a loadshed controller, the optimum control point is determined based on the metering inputs, time remaining in the block interval and the user-programmed target. The optimum control point is used to shed or restore loads via the controller’s relay outputs.

The Elpro 105U-4 wireless transceiver with up to 16 digital inputs signals the remote points to shed the load. At each load cluster an Elpro 105U-L receiver with up to 3 relay outputs controls the loads. The system will operate in a license-free 800MHz band and can be implemented without delays on site. Distances between the controller and loads can be up to 5km. Our clients across industries are often rewarded for participating in the optional load control programs by paying a reduced rate for energy.
