光星計測器（LIGHTSTAR） List of Products and Services

To prevent accidents caused by increased load rates, it is necessary to maintain an appropriate reserve margin and control the temporary maximum demand power. Accordingly, Korea Electric Power Corporation has implemented a system where the maximum demand power is included in the basic charge to encourage users to voluntarily manage their maximum demand power. Sustainable management of maximum usage electricity is essential to keep the basic charge low. For managing maximum usage electricity, a maximum demand power controller should be used to set a target electricity amount. The usage electricity (peak power) should be continuously monitored to ensure it does not exceed the set target power. If the current power exceeds the target power, loads that can be temporarily turned off, such as air conditioners, refrigerators, pumps, and HVAC systems, should be automatically and cyclically disconnected. Once the usage power is at or below the target power or the demand time limit ends, the load power supply should be automatically restored to control the maximum demand power. Features: - Economical - Panel-mounted design allows for attachment to distribution boards - Easy monitoring and setting with 16 buttons and an LCD display Demand Controller IV For inquiries, please contact "lightstar_1979@yahoo.co.jp".
