ASCO 7000 Series Low-Voltage Power Control System

The ASCO 7000 Series Low-Voltage Power Control System is custom-configured and manufactured to parallel standby and utility sources for both low and medium voltage applications to meet the complex emergency and prime power requirements of mission-critical facilities. The 7000 Series is designed, manufactured and thoroughly tested and certified to the toughest global standards, for operations of all sizes and requirements.

The benefits of paralleling different power sources include;

Utility Load Curtailment – When utilities direct users to reduce demand, facilities can use generators to provide supplemental power instead of curtailing load.
Peak Shaving – To avoid demand charges, facilities can run generators to replace a portion of utility power during peak use periods.
Parallel Utility, Generators, and On-Site Renewables – Parallel two or more power sources to enhance reliability, reduce energy consumption, and lower energy costs.

Monitoring and synchronizing generators is essential for any electrical system served by more than one power source. The 7000 Series PCS synchronizes and connects multiple sources after comparing voltage, frequency, and phase angle. They can parallel multiple bus segments to connect priority loads quickly. Generator Load Demand maximizes the efficient use of standby generator capacity by adding or removing generators according to demand. It ensures reliability and availability by connecting sufficient power when needed. It conserves fuel and reduces engine-generator wear-and-tear by operating fewer generators at higher efficiencies.
