Single phase solid state relay categories
Lorentzzi® Single Phase SSRs include Panel Mount AC SSRs, Panel Mount DC SSRs, DIN Rail SSRs. More than 10 years of SSR manufacturing experience make us your trusted business partner. Our single phase SSR current ranges from 10 amps to a maximum of 120 amps. These solid state relays are widely used in heating control, stage lighting, and other applications.
Panel mount AC output solid state relay
The panel mount AC output solid state relay here contains DC to AC SSR, AC to AC SSR, they are designed to fix on a flat panel by 2*M4 screws.
Panel mount DC output solid state relay
The panel mount DC output solid state relay here only refers to DC to DC SSR, they are designed to fix on a flat panel by 2*M4 screws as well.
Din rail solid state relay
This DIN rail solid state relay has been installed on a suitable heat sink already. Besides, it has a DIN rail structure, so we can place it to the 35mm DIN rail very easily.

Frequently asked questions
What is a single phase solid state relay?
A single-phase solid-state relay (SSR) is a semiconductor-based switch, using either a thyristor(AC SSR) or MOSFET(DC SSR), that uses a 3-32 VDC or 70-280 VAC control signal to turn the load on and off. It has no moving parts and therefore has a service life of at least 10 years under normal operating conditions.
What are the advantages and disadvantages of a single phase SSR?
Single-phase solid-state relays have the advantages of fast switching time (usually milliseconds), no sparks when closed, and no noise. The only disadvantage is it can generate a lot of heat during the long operation, thus we should use it with a suitable heat radiator to avoid overheating.
What are the applications of single phase solid state relay?
Single-phase solid-state relays are mainly used in single-phase temperature control systems and can be used with PID temperature controllers to control heating elements. Typical applications include industrial automation control, such as motor control, solenoid valve control, lighting control, constant temperature control systems (such as furnaces, ovens, etc.), packaging machines, plastic manufacturing machines, etc.
How many types of the single phase solid state relay?
The single phase solid state relay can be classified by many aspects, such as switching mode differences, control signal differences, load types differences. You can get more knowledge from our blog: Solid State Relay Types: How to Choose the Right SSR for Your Application.
Is the single phase SSR better than single phase AC contactor?
It depends on the specific situation. In special occasions such as temperature control systems that require fast switching frequencies and explosive gas stations, single-phase solid-state relays are preferred due to their fast switching time and no moving parts. In motor control, AC contactors are preferred because of their strong load capacity.
How should I wire a single phase SSR?
Wiring a single-phase solid-state relay (SSR) is straightforward. You can refer to our blog, “How to Wire a Solid State Relay?” for detailed instructions to ensure a proper connection.
Does the single phase SSR have a normally closed type?
No, there is no normally closed solid state relay in the market, all single phase SSRs are made with normally open due to thyristor, it is different from electromagnetic intermediate relay or power relay which is made with normally open and normally closed contacts.
What is your single phase SSR warranty?
We can provide 2 years warranty for all SSR, no matter it is single phase or three phase SSR, our warranty policy is, if the SSR is damaged due to our reasons such as quality problem, we can send you new products without reason, if you use it in wrong way, we can guide you to repair it.
Can I have you produce under our brand?
Yes, we can provide ODM service for free, but there is a minimum order quantity requirement, the total purchase quantity must be at least 200 pieces (different models can be mixed).
