Sosen LED Driver SS-120V-38

Good afternoon,

I am looking to replace an LED Driver. The Driver I have is Sosen Model: SS-120V-38

I was not able to find it on your website, I’m guessing this has been discontinued. If that is the case do you have something


? Please let me know.

Thank you,

I wasn’t able to locate a spec sheet on this driver. I’m unsure if it’s type (constant current, constant voltage, etc.) Are there adjustable potentiometers on this driver?

The only thing I’ve been able to find is that it is non isolated constant current. I hope this info helps.

Thank you!

A constant current shouldn’t have a current range. I’m going to research this further.

Thank you so much Jeff! I greatly appreciate the help.

Thank you!

That can show up on devices that have a knob to allow adjustment of the output current setpoint.

Labeling of the sort would indicate that turning said knob produces an output current of ~2.2A at one extreme and 3.8A at the other, so long as the resulting output voltage is maintained between 24 and 38V and the product of the two doesn’t exceed 120 watts.

It’s not obvious whether the device in question includes a dimming functionality or not, what flavor if so, or if it’s actually used in the appliation. A wider view may offer some clues to that effect.

I’d point to these devices as ones we have available that seem like they might be in a nearby ballpark. Identifying the characteristics of the driven LED load, the actual setting of the adjustment knob in the application, or other information about what’s actually needed would be helpful in narrowing the options further.

I’d view the non-isolated part of that with some suspicion, since non-isolated supplies have limited application and aren’t often found in IP67 flavor.

Finally, if using the reply-by-email feature to post to the forum, I strongly recommend deleting the info in one’s signature prior to sending unless one wishes to make one’s name, email, phone numbers, etc. publicly available for all the internet to see. I’ve edited prior posts to remove this information from public view.

Thank you so much! I didn’t even think about my signature line, thank you for the heads up. I will make sure to reply in the forum instead of from my email. I will check out the devices listed. You are AWESOME!

Thank you!
