Product Overview & Applications:
The LCTC Solid-State Relay is a versatile and reliable electrical component. It performs its functions effectively in both AC control DC and DC control AC conversion processes. Thanks to its robust design and sealed protective features, this solid-state relay ensures exceptional longevity and reliability—even in plasma environments. By leveraging solid-state technology principles, it serves as a superior alternative to traditional electromechanical relays, thereby providing customers with a more efficient and dependable solution for electrical control. The SSR relay also allows for customization, with zero-cross turn-on being the default and random turn-on available upon request.

Choose a correct control Model
Choose a correct type
PS: The Ratio depend on the type of your loading equipment.
Resistive load :70%
Note: This type of voltage regulator module is not suitable for inductive loads such as transformers and motors.
Choose A Suitable Heat Sink
1.When SSR is working, it will give out a lot of heat, so in order to extend the life of your SSR, please install a heat sink.
2.If the current is over 60A, a cooling fan is also required.
3.Don’t forget to apply heat-conductive silicon grease between SSR and heat sink.
Note: The radiator needs to be purchased separately!
Precautions
If you wish to perform a test, you need to connect a load to the solid state regulator.
