8 steps for choosing a solid state relay manufacturer

The above list outlines the world’s top 10 solid-state relay manufacturers and suppliers, but now another question arises: how do you choose the right solid-state relay manufacturer to provide you with reliable products and better services?

The following 8 steps can be followed:

Step 1: Check the factory's production capacity

Different manufacturers have different production capacities, so how do you determine their production capacity?

The answer is simple: examine the number of their production workers.

Generally speaking, companies with more employees demonstrate a stronger ability to produce solid-state relays in a short time.

Therefore, if you have an urgent order, choosing a factory with more workers is a good option.

Step 2: Check the manufacturer's certifications

Solid-state relays require numerous certifications across different countries/regions, such as UL, ETL, CE, RoHS, UKCA, and CSA.

UL, ETL, and CSA certifications are geared towards the North American market; CE and RoHS certifications are for the European market; and UKCA certification is for the UK market.

Manufacturers or suppliers with more certifications are generally considered more competitive than their counterparts who lack them. From another perspective, this also demonstrates that the manufacturer’s products meet more stringent standards.

Step 3: Check their product components

Solid-state relays are composed of components such as resistors, capacitors, optocouplers, thyristors, or MOSFETs.

Excellent solid-state relay manufacturers always use high-quality components. For example, thyristors or MOSFETs are the most important parts of a solid-state relay, as they are responsible for controlling the connection, operation, and disconnection of the load. Using inferior components will greatly shorten its lifespan.

Step 4: Do they have R&D ability or not?

Solid-state relay R&D capabilities

Strong R&D capabilities are another aspect that cannot be ignored, which can be clearly reflected in the number of engineers in the supplier.

When you encounter product quality issues, suppliers with more engineers can provide your customers with better and more timely technical support.

Step 5: Find out their prices

When selecting the best solid-state relay partner, price is always the most important factor.

Only suppliers who can offer the most competitive prices and the most reliable products can prove their strength.

Step 6: Do they have a minimum order quantity requirement?

In professional overseas sales, the minimum order quantity is often simply referred to as MOQ.

If a solid-state relay manufacturer or supplier is willing to accept a lower MOQ, it means they are more willing to support your business, which is a great opportunity for a startup.

Step 7: Experience their pre-sales and after-sales services

Before you finalize your choice of a solid-state relay (SSR) manufacturer, it’s best to experience their pre-sales service first. You can test their professionalism by placing a sample order.

Pre-sale services include: smoothness of communication,  professionalism of document preparation, timeliness of responses, ability to understand and respond to professional questions,  taking of photos before shipment, and the preparation and confirmation of documents, etc.

Now let’s look at after-sales service. Good after-sales service includes: accepting customer complaints, calming customer emotions, and proposing solutions in a timely manner, such as product replacement and free spare parts.

Step 8: Their history, reputation, and complaint rate

A solid state relay supplier with a long production history is an important indicator that they have been deeply involved in the field for many years and are highly professional. You can find this information on their website, business license, or competitor reviews.

As for reputation and complaint rates, you can find this information on websites like Quora or Reddit.

Conclusion

The 10 solid-state relay (SSR) manufacturers listed above all offer high-quality SSRs, but if you need a supplier that provides high-quality SSRs at competitive prices, Lorentzzi® is your best choice in China.

Lorentzzi® also offers ODM and OEM services to help you enhance your brand’s market presence.
