Solid State Relays.

Solid state relay (SSR) is a kind of relay which uses semiconductor switch elements instead of electromagnetic coils as the switching element. Its advantages are: direct output, no spark, no electromagnetic interference, fast response, small size and light weight. SSR can be divided into two categories according to output mode: AC output and DC output.

SMP-2A30-8ST is a type of DC output solid state relay, developed by Motor Control Technology Co. Ltd. It features rated current up to 2A, two isolation distances between input,output and case of up to 3mm,turn-on/turn-off time of <5/15ms and temperature range of -40℃ to +85℃. It comes in a 10 × 10 × 8mm enclosure, making it small and compact for limited installation space.

Applications Field of SMP-2A30-8ST.

Due to its high performance, the SMP-2A30-8ST can be applied to various applications. It is frequently used in automotive, LED, and digital signage fields.

In the automotive field, SMP-2A30-8ST is used in P-RKE (Passive keyless entry) systems. P-RKEs detect the proximity of an authorized user and unlock the car without requiring the user to manually unlock the car. SMP-2A30-8ST’s fast switching response and high reliability makes it ideal for this application.

In the LED field, SMP-2A30-8ST is used to drive LED lighting devices. Since LED devices require constant current to be supplied, the SMP-2A30-8ST can provide regulated constant current thanks to its stable and precise output current. This ensures a longer lifetime and reduced power consumption of the LED devices.

In the digital signage field, SMP-2A30-8ST is used to provide reliable power control for digital signage displays. Digital signage displays require stable power supply in order to ensure the reliability of the displayed information as well as provide greater picture quality. The output of the SMP-2A30-8ST is highly reliable, allowing it to meet the requirements of the application.

Working Principle of SMP-2A30-8ST.

The SMP-2A30-8ST is a DC output solid state relay. The following flowchart depicts the working principle of the SMP-2A30-8ST:

1. AC input is supplied to the relay.

2. The AC input is rectified by the rectifier bridge, producing DC output.

3. The DC output passes through the sensing module, and is detected by the electronic switch.

4. The electronic switch is then used to control the switching of the motor.

Thus, the SMP-2A30-8ST is able to precisely control the on/off status of the motor. The working principle of the SMP-2A30-8ST ensures precise control and high accuracy of motor switching.

The SMP-2A30-8ST is a type of DC output solid state relay which can be applied to various applications such as automotive, LED, and digital signage. Its working principle is to rectify AC inputs, detect outputs, and control motor switchings. It features fast switching response and high reliability, making it a perfect choice for applications requiring precise control.
