What is a Demand Controller?

A Demand Controller is an advanced system designed to measure and manage energy consumption in real-time. It helps predict peak demand, monitor power quality, and optimize energy usage across commercial and industrial applications.

How does the Demand Controller help improve energy efficiency?

The Demand Controller predicts maximum demand and manages loads during peak periods to reduce energy waste and costs. It offers real-time monitoring and detailed energy logs, helping users analyze usage patterns and improve overall efficiency.

Can the Demand Controller be used for large industrial applications?

Yes, the Demand Controller is built for large-scale applications and can handle high voltage and current with accurate energy measurement. It's ideal for factories, data centers, and other high-power usage environments.

Does the Demand Controller offer remote monitoring?

Yes, the Demand Controller comes with a built-in web server, enabling remote monitoring of real-time data. You can access key parameters, waveform visualizations, and historical power data remotely via Ethernet or RS485 communication.
