The relay is suitable for a wide array of power applications, such as motor speed control, AC/DC switching and load/unload control in HVAC and industrial equipment.

Application Field:

This 3-phase, 16A relay is an ideal choice for general purpose and industrial loads such as motor controllers, process control, computer peripheral control, HVAC, and even lighting applications. The wide working range makes it an attractive option for multiple applications, while the slim body and compact size prevents overheat and overload. The RT3SN-12V has been designed to be robust, making it a reliable choice for industrial applications. Additionally, the relay has a built-in adjustable timer for on/off control, making it an ideal choice for applications where timing is important.

Working Principle:

The RT3SN-12V relay is a zero-crossing, solid state relay that works based on the premise of electronic control. When voltage is applied to the relay, a field effect transistor (FET) is used to switch the current and subsequently close the contacts of the relay. This is done by the magnetic force of the energized coil, which creates a slight magnetic field around the coil. If the requisite voltage is sufficient, the magnetic field pulls the contact head against the metal contacts and closes the circuit.

The RT3SN-12V relay\'s working principle provides several advantages. The closing of the contacts is done at zero crossing, which minimizes noise and improves the relay’s endurance. Additionally, the RT3SN-12V utilizes a zero-voltage release feature, which prevents undesired switching of the relay in the event of a sudden voltage glitch or surge. Furthermore, the relay has an adjustable time delay to protect it in the event of an event of over-voltage or overload. This reduces the risk of damage from over-voltage or overload.

Conclusion:

The RT3SN-12V is a reliable, high performance, and compact solid state relay that is ideal for various industrial and commercial applications. It features a wide working range, built-in adjustable timer, ultra-fast switching and energizing capability, and zero-crossing control for extremely fast switching. Additionally, it can also handle over-voltage and overload protection due to its adjustable time delay feature. With its robust design and low power consumption, the RT3SN-12V is an ideal choice for applications where timing is important.
