Note:

When the load is a resistive load, the maximum load current of the selected SSR should be 2~3 times greater than the actual load current;
When the load is an inductive load, the maximum load current of the selected SSR should be more than 7~8 times the actual load current.
When the maximum load current is higher than 10A, a heat sink must be installed to the solid state relay, or the SSR relay should be mounted on a metal base plate with heat dissipation effect, and the thermal grease is applied between them.

Tips: Zero-crossing Solid State Relay vs Random Turn-on Solid State Relay

When a valid control signal is applied at the input, the random solid state relay output is immediately on (in microseconds) and the zero-crossing solid state relay is turned on until the load voltage crosses zero (± 15V). When the control signal is undone at the input, the zero-crossing and random SSRs are turned off at the time when their holding current fails.

Although they are likely to cause a maximum half-cycle delay, zero-crossing solid state relays reduce the impact on the load and RF interference, which makes them ideal switching devices that are most commonly used in "single-pole single-throw" switching applications.

Random solid state relay is characterized by fast response. It can control the phase-shift trigger pulse to easily change the AC grid voltage, and therefore, it can be used to accurately adjust temperature, dimming and other resistive loads and some inductive loads occasions.

Solid state relay (SSR) is simple but widely used in the automation fields. Thus, it is not complex to wire a solid state relay. In this vedio, ATO takes a 40 Amp SSR (DC - AC) for example to show the wiring of a SSR and then switch on/off a motor with this SSR.

How to Test a Solid State Relay?

Solid state relays are commonly used to control many electronic components, so if a component isn't working because there's no current flowing through it, it's likely a problem with the relay. With some simple troubleshooting steps, it's easy to check if an SSR is working as expected. In this video, we'll show you step-by-step instructions on how to test a solid state relay.

Types of Solid State Relays

There are different types of solid state relays according to various classification standards. In this video, we will introduce a series of different types of SSRs according to the following standards.

DC-AC/AC-AC Single Phase Solid State Relays

In this video we take a quick look at ATO's current single phase SSR models along with their specifications and key features. They are designed to operate high load currents using low control currents, using our advanced opto-isolation technology.

Electromagnetic Switches: Relays VS. Contactors

In this video we will try to clear the confusion many people have between relays and contactors by showing you how to tell the difference based on five criteria: Definition, Capacity, Structure, Contacts and Applications.

Relays vs Circuit Breakers: What’s the Difference

In this video, we've described the difference between a relay and a circuit breaker as well as explaining their basic working and operation by means of animation.

Existing reviews of Solid state relay SSR-80DA, 80A 3-32V DC to AC

I have some questions

Could you answer some questions? Has the SSR's have built in protection to switch off if the current exceeds 80A? Is 80A continuous? Does the SSR have a peak current draw more than 80A?

ATO Responded

For motor load, we usually need to enlarge the current capacity of SSR by more than 5 times to use it safely.
If you choose a smaller model, we recommend that you change to a larger capacity model. SSR does not have built-in shutdown protection, and overcurrent use may directly damage it.

I was looking at your 80A DC to AC solid state relay.

I see the control voltage is DC, do you make a SSR with control voltage 120VAC?
We are currently using the N-95 Mitsubishi contactor for our heater circuit on machine. 480vac 3 heater bands total 34KW 480vac and using 120vac as control voltage.

ATO Responded

Ok, in that case, we recommend using a solid state relay, 3 phase, SSR-120AA, of model: ATO-SSR-TH120AA, 120A current capacity, 70-280V AC control voltage.
