Power Relays, Over 2 Amps

PRD-3DH0-24 Application Field and Working Principle

The PRD-3DH0-24 is a family of power relays for applications with currents that exceed 2 amps. It is a medium-voltage device that is typically used for controlling electrical motors, lighting, and other high-power devices. This type of relay is specifically designed to operate in medium to high voltage ranges and provide excellent current capacity.

The PRD-3DH0-24 is a construction class power relay that is constructed with a combination of two modules. The first module is the solid-state relay (SSR) that features UL recognized components and is protected with an external over-temperature detection (OTD) device. The second module is the mechanical relay (MR) that provides the switching capability. Both modules are combined in a plug-in socket and the output contacts are connected to the load device. This setup provides a high level of flexibility to the user and allows the PRD-3DH0-24 to be used in both single-channel or dual-channel applications.

The PRD-3DH0-24 operates on both AC and DC voltage sources and can use either Sine Wave or Square Wave power sources. It is also capable of varying over-current detection ranges, which allows for precise current protection and control. This type of relay has a variety of safety features including an OTD detector, short- circuit protection, and an extended life cut-tac contact for secure switching.

PRD-3DH0-24 relays can be used in both high voltage and low voltage environments and are ideal for motor control applications. The relay is designed to provide reliable operation under extreme temperatures and high humidity levels. Additionally, it features a variety of indicators and fault lights that provide easy and precise monitoring.

The PRD-3DH0-24 is a versatile and reliable medium-power relay that can be used in a variety of industrial and commercial applications. It is suitable for applications that require high current capacity and precise control. This device is designed for long-term use and is easily integrated into existing systems.
