Solid State Relays

A Solid State Relay (SSR) is an electrical device that utilizes solid-state components to replace the conventional mechanical relay or contactor. A solid state relay operates by controlling electrical current or voltage and is actuated by the application of a voltage or signal to its terminal. This type of relay is ideal for situations requiring the switching of high voltages or high current load sources, as it offers reliable and repeatable operation at a relatively low cost.

The TP15F solid state relay (SSR) is a powerful, 25-amp, single-pole, double-throw (SPDT) device. It is designed to be used in harsh environments, such as automotive, industrial, and medical equipment. The TP15F can also be used in high-temperature applications, and is UL compliant, offering overcurrent, overvoltage, over-temperature, and protection from harsh thermal shock.

Application Field

The TP15F is ideally suited for applications that require switching on and off of high-power electrical loads. It can be used in automotive applications for controlling motors, lighting, audio systems, and other high-power electrical accessories. In industrial and medical applications, the TP15F can be used to control electric motors, resistive loads, and lighting.

The TP15F can also be used for applications requiring control of a load over long distances. With its robust design, it is an ideal choice for applications where the relay needs to be located in a place that may be inaccessible or difficult to access. It can be mounted up to 10m away from the control power source, allowing for much greater flexibility in the placement of the load.

The TP15F is also useful for applications requiring the switching of low-current or low-voltage loads. The device offers a low-voltage drop across the relay contacts, allowing it to be used even for very low-power loads.

Working Principle

The TP15F operates by utilizing a solid-state device called a triac to open and close the contact between the low and high side of the relay. The triac is triggered in the on state when a voltage is applied at the gate of the device, allowing current to flow through the relay. When the voltage is removed, the triac switches off again, and the circuit is opened again.

The TP15F also includes overvoltage and over-temperature protection mechanisms to ensure that the relay does not cause damage due to sudden voltage spikes or thermal events. This device also contains surge suppressors, which help protect the contacts of the relay from damage due to voltage surges.

The TP15F relay can be remotely controlled via a switch or by using an adjustable voltage or current source. It can also be configured to use a mechanical switch, such as a button, to control the opening and closing of the relay, allowing for complete user control and customization.

The TP15F relay is an ideal choice for applications requiring the switching of high-power loads. Its robust design, low power requirements, and relative affordability make it an excellent choice for applications in the automotive, industrial, and medical equipment fields and beyond.
