The 4000 Series Generator Paralleling Switchgear debuts ASCO's next-generation digital paralleling controller. The unit offers the reliability of an industrial programmable logic controller.

The unit provides true, integrated control of each engine-generator and simplifies power system operation, control and communication.

The controller automatically operates the system to efficiently add loads to the bus. It also ensures that engine-generators assume the highest priority loads first and manages the number of engine-generators needed to power those loads.

Operation is immediate and reliable, giving you peace of mind. Operational parameters can be set up through the touch screen, without a laptop computer.

The controller provides unsurpassed control of your prime power, emergency and/or standby system using touch screens. Power monitoring, generator control, automatic transfer switch intelligent transfer and soft loading and unloading can be managed through the controller.

The capabilities of the digital paralleling controller enable you to tailor the breadth and ease of control you want in your on-site power system.

The controller communicates through Ethernet connection with a range of building networks using most major media and protocols. Seamlessly integrating with your existing communications infrastructure eliminates the expense of extra hardware and software, and facilitates start up.
