HPS-RR

Fuseholders

High Power Switching Reliability (HPS-RR) is a paperless, printed circuit board mounted, high voltage, high power switch module circuit design. It is ideal for applications in power systems, motor drives, and medical equipment. HPS-RR can be integrated into different types of fuseholders and provides an economical solution for equipment protection.

Application Field of HPS-RR

HPS-RR can be used in a variety of applications, from medical equipment, motor drives, to power systems. Its integrated protection features, such as current sensing and open circuit fault warning, make it a valuable asset. HPS-RR\'s ability to work with different types of fuse holders, from traditional ceramic single-sleeve designs to PC board type holders, makes it highly versatile.

HPS-RR is a great choice for medical equipment and motor drives since it can easily be integrated into existing designs and provide safe operation. For power system designs, it is perfect for cost-effectiveness, since it eliminates the need for components such as capacitors and variety of different fuse types. Moreover, its automatic resetting feature enables automatic recovery from some of the electrical faults ranging from currents overload, short circuits and open communications.

Working Principle of HPS-RR

HPS-RR works through its integrated printed-circuit board mounted switch module circuit design. It utilizes a relay or contactor-like mechanism to provide the operating point for a given load. It has two primary components, the switching network and the current-sensing network. The switching network is responsible for controlling current and voltage through the contacts, while the current-sensing network ensures that the proper amount of current is being supplied to the contacts.

When the load current reaches the threshold set by the sensing network, the contacts open and close in a relay-like manner. This communication between the contacts is realized through the switching network. The switching network closes the contacts, allowing power to be supplied to the load. When the load current drops below the threshold set by the sensing network, the contacts open, thus protecting the load.

The current-sensing network utilizes a variety of components like resistors, capacitors and inductors to detect the load current and protect the load from overload or short circuits. Moreover, the current sensing network is designed to provide an alarm when the abnormal load current is detected, thus providing an early warning system. In case of a short circuit, the contacts will remain open, protecting the load.

HPS-RR provides a reliable and efficient solution for equipment protection, especially in environments requiring a high level of design flexibility, such as medical equipment or motor drives. Its integrated protection features, such as current-sensing and open-circuit fault warning, provide comprehensive protection for the load.
