Product Description

This model is a single phase solid state relay with 25A AC to AC control, UL approved and certified to EN60950-1 by the CE.

Max load current 25 A, input voltage 80-250 volts AC, load voltage 24 380 volts AC

The epoxy encapsulation construction delivers high isolation over 50 millions of volts (500VDC) and high dielectric over two million volts. The output has a snubber circuit with a 5KV rating

By the Zero Cross Trigger method, there are no EMI/EFI and no surges, making it the ideal solution for regulating sensitive, capacitive, and inductive loads.

The SSR switch uses a semiconductor component that acts as a switch for the relay, so there are no moving parts inside, no mechanical wear, no action noise, and no mechanical failure.

Questions & Answers

What is the maximum current the DC DC relay can handle? Are there any limitations? Did you connect it to a fuse?

That should be the case. It's a good idea to always have a fuse handy.

Worked for me

4/5

With a simple open contact flood sensor, it was used to complete a circuit. In a relay running at 12 V there's a substantial voltage drop, but this contact will still close at In my tests it was recommended that it be no lower than 3v. When I use my relay I am able to get 7ish volts, which creates a circuit. By shutting off the valve, this will prevent further flooding by sending power to the normally open valves. With 12v run it doesn't get hot, but I still attached the large heat sink with no paste so it would remain For that, I had to find some screws. It could have been included, so minus one star because two screws are missing.

resistance in the output of the relay Unfortunately, it could not be used

3/5

It was just the thing I needed The relay failed to work for my project because, when activated, it had high resistance and wouldn't power on the dust collector (due to high resistance when the contacts were closed). Purchased a third as a backup just in case, as well as returned the first to get another one There is the same issue with all of them. It was really a waste of my money and my.

It works well as long as it does not exceed 20 amps

5/5

There are no signs of failure with the relay. This is the first time I've ridden it hard. It is suggested to use no more than 20 amps on a continuous basis. I would guess it would be about 40 amps. However, that is the case with every relay.

A heated bed for the 3D printer is used as well as for a heater in the chamber

5/5

The trigger level for low level attacks is A heated bed for the 3D printer is used as well as for a heater in the chamber. The trigger level for low level attacks is With the big tree tech mcu board we have 3v and we only use 10 of the rated 40 amps, so I manage to remain within the 1/4 utilization window that makes sense for our printer for the day.

The heatsink may have to be installed at some point

5/5

As far as my application is concerned, it works just fine. That it worked was appealing to me Remotely receives a remote control signal from a 12 volt low power source. That signal turns on a higher power 12 volt supply to light and sound a warning The alarm is for an intrusion. I have no problems with it.

The setting up process is simple and easy

5/5

This works as it should. In my case, I use it between 12A and 30A and the heat sink gets warm to the touch after 20 to 30 minutes Take their advice about the heat sink seriously if you plan to use it 30 minutes.

I really liked how it worked! It worked well in a controller box I built for an automated stoplight parking system in The products worked exactly as advertised and were of high quality

This relay controls the transbrake

5/5

My transbrake and bump work great with this device. Check to make sure the voltage goes from DC to DC. One that converts ac to dc is not up to the task.
