The AFP7FCTC2 is an invaluable tool for ensuring reliable, uninterrupted access to power for critical loads. It is part of the SEL family of power controllers, accessories, and analyzers designed to control the flow of power through an electrical circuit and return the system to its normal operating level in the event of a power outage. In this article, we will take a look at the application field and working principle of the AFP7FCTC2.

The AFP7FCTC2 is a transient fault controller designed to protect critical loads such as lighting, HVAC systems, industrial processes, and critical communication systems from short-term power outages or transients. It is designed to detect the presence of current transients, such as lightning strikes, and respond by throttling the incoming power to the critical loads. It is also designed to operate in two modes, one designed for maximum protection, and the other designed to provide gradual restoration of the power circuit.

In its maximum protection mode, the AFP7FCTC2 will detect a transient or power outage and immediately close the incoming power source to the protected load. This will prevent the transient from damaging the load, as well as prevent the system from overloading or experiencing a blackout. The controller will then restart the power source, slowly ramping up voltage and current to the load until normal operation is achieved. This mode is ideal for protecting a system against extreme transients or short-term power outages that could cause catastrophic damage.

The other mode of operation is the gradual restoration mode. In this mode, the AFP7FCTC2 will detect a fault or power outage and respond by slowly ramping down the incoming power to the critical loads. This will allow the system to recover gradually, ensuring that it is not overloaded or damaged by the incoming power while restoring normal operation. The controller will then slowly ramp up the incoming power and return the system to its normal operating level.

The AFP7FCTC2 is a reliable and versatile tool designed to protect vital systems against power disruptions or outages. By providing a quick response to transient events and the ability to gradually restore power to the system, it can help to ensure that your critical loads remain properly powered and operational, even in the face of extremely challenging conditions.
