I bought a box of DC to DC SSR -100 DD (SSM) and tried to use it as a battery isolator or switch relay for my 84v 48A ebike battery to turn off power to the e-bike controller. Input V is 3-32vdc on terminals 3 - 4 (+ and -) and that works as I tap off the battery for the 12vdc from 3 banks of the 20 banks. But once I apply the positive cable to the output side (the switch) from the battery 84v to terminal #1 and the controller positive in terminal #2 it fails instantly. Specs say 100A 5-200vdc on the output side. Not sure if tapping off the 3 banks is destroying the SSR or if I need diodes ?? I'll try a different power supply to the input voltage to see if that makes a difference.

@FadsToObsessions 3 жыл бұрын

If I understand your setup properly, having the same power supply (even though tapped off at different points in the series) as both the control voltage and "load" voltage to be switched does sound like the problem. If you have time, post the results of your testing.

As a bit of an understanding on these devices (which IMO and like you stated) the expensive ones are the way to go. Safety is paramount, buy trusted parts for dangerous operations. Inspect current regulation at the source, and make sure your device is within acceptable ranges. It's good to keep in mind that the main idea behind these SSR's is usually to throttle a heating element like on your stove top range. Most still have a relay for the oven bits and you can hear the click. But none for the element. That's because they have to switch on and off A LOT to maintain consistent heat at the element. If you did that with a relay, it would by noisy, and it would fail within a year. That's why these exist in the first place. Now that doesn't mean that you can't use them as glorified switches. I mean, it's what they are. They do allow for continuous amperage, but again, it wasn't the specific mode of operation that they were designed for. For switching, I would MASSIVELY oversize ANY SSR with a standard 120V outlet. You can't predict all the wiggly plugs that might make it to this circuit to test your design.

@stupidscruff5794 Жыл бұрын

I bought a couple of these for a little DIY wind turbine dump load circuit, I think it should be fine for that as it's only 12v and won't be running anything over 8amps. Just figured it would be more reliable than a traditional relay. I didn't know they sold fake ones but luckily I ordered much higher tolerance than I need lol

you had mentioned control signal to be 5V dc, but relay says 3-32 vDc, and also the datasheet, so I should be able to control it with a 3.3v esp32, right?

Hello. your video is very interesting. I would like to know if it is the small 9v battery that powers the electrical devices through the ssr-40 DA relay. thank you very much

@FadsToObsessions 3 жыл бұрын

The 9V battery is only providing the CONTROL voltage (which can be from 3 to 32V DC) across pins 3 and 4, whereas, any "electrical devices" are powered by AC voltage (240V AC in this case) connected to pins 1 and 2. If the CONTROL voltage (from a battery or similar DC source) is ON, then the SSR will power the electrical devices using the AC voltage.

@salifdieme5863 3 жыл бұрын

@@FadsToObsessions thank you. But is the ac output of the ssr-40 relay connected to a source of electricity (from the house for example) or not? in fact i would like to know if the ssr-40 relay can operate the pump without connecting the ac output of the relay to a source of electricity or it is imperative that the ac output of the relay is connected to a source of electricity. if you can give me some clarification.

@FadsToObsessions 3 жыл бұрын

@salif, the SSR-40 must be connected to a AC source of electricity (from the house for example as you say). The SSR-40 can be thought of as only a type of "switch", one that can be opened and closed by using a DC control voltage (instead of manually with your hand) which means it can be controlled by some circuit or sensor for example.

@kaveengoonawardane9651 2 жыл бұрын

Great video! Quick question thought. If I use a SSR with an input voltage of 230v, will it instantly switch once the input voltage reach 230v?

@FadsToObsessions 2 жыл бұрын

Kaveen - I'm not clear on what you are asking, but the input voltage (across terminal 1 & 2 of the SSR) has to be AC (and between 24 to 380 VAC) and obviously varies sinusoidal, so if you are asking is the SSR "zero crossing", the datasheet does say it is suppose to be "zero cross trigger method" - although these fakes are obviously suspect at best. The SSR "input" (terminals 3 & 4) is DC voltage between 3 and 32V. If a DC voltage of between 3 and 32V is connected to terminals 3 & 4 (notice the polarity indicated on the face plate), whatever AC voltage is connected across terminals 1 & 2 will flow. Be careful not to "mix-up" the AC and DC voltages. Hope this helps.

Does the relay require a load to engage or will it engage before the load is present?

@FadsToObsessions Жыл бұрын

As long as a DC voltage between 3-32V is "across" terminals 3 and 4, the relay will "engage" and terminals 1 and 2 will form a closed circuit

@FadsToObsessions Жыл бұрын

It would be correct to be sceptical of any such components (made in China or any where else) that are "too good to be true" in terms of price. The adage "if it's too good to be true" it's often because it is not "true".

@EnergySeeker 2 жыл бұрын

is it zero crossing ?

@FadsToObsessions 2 жыл бұрын

I believe the datasheet for the genuine versions state that the optoisolator incorporated is zero crossing. BUT, since these cheap "ebay" versions have to be assumed as fakes, you cannot be certain as to what actual components have been used internally.
