    LCD8S and KT48SVPRK sine wave controller.

    Wow these are much smaller and way better of a form factor for this need. Thanks Amberwolf!! So now I have another question, is the 15V supply necessary for other components on the KT controller or is it's sole purpose to be stepped down to 5V? From what I had gather by measuring voltages and...

    LCD8S and KT48SVPRK sine wave controller.

    So this morning I tore apart my brand new LCD8S and measured all the voltages I could find, minus the USB charger module which is separately attached to the rear of the display casing. Here it is. I hope it services someone who stumbles upon this sometime. Personally, Id suggest just buying...

    LCD8S and KT48SVPRK sine wave controller.

    So this is the buck converter I am using: And it's description states: Found on Amazon: https://amzn.to/3f9VQWK This is as good of a pic as I can get of it, should hopefully be pretty clear: So am I correct to assume this is a linear converter? It doesn't appear to have as much heat loss...

    LCD8S and KT48SVPRK sine wave controller.

    Good question. I am not sure. I had assumed it just didn't withstand the test of time but I may be wrong. When this happened I had to change the LM317T and the resistor at the same time. Then onto the A1013 in the LCD8S. I would guess heat energy and my high voltage/current stressing the...

    LCD8S and KT48SVPRK sine wave controller.

    Thank you for the information amberwolf! I ended up installing this buck converter again in place of the resistor and something again backfired in my LCD8S. This makes me think that wiring a diode across the place of the former resistor might be worth looking into. I am unsure if my buck...

    LCD8S and KT48SVPRK sine wave controller.

    So for future reference, a capacitor was at fault. The LCD8S has a 10uf 63v surface mount capacitor that I replaced and it fixed my issue of voltage appearing to sag. I first had to change the A1013 transistor that had blown, and a resistor up on top of it as well. I am still working on...

    LCD8S and KT48SVPRK sine wave controller.

    Yes I read the whole thread. I think you missed the part of my post where I had replaced the LM317T entirely with a buck converter. I had the same issue. To be fair I think I might have included a different image where I had used the buck converter in front of the LM317T. I'll clarify, I...

    LCD8S and KT48SVPRK sine wave controller.

    I don't see why that would prevent it from working off the bat as 48v controllers are typically ran with 63v capacitors which is precisely what I have. In addition to the fact that my ZWS square wave is the same model exactly absent the ADC. The mosfets are rated for 85v and 150 amperes, which...

    LCD8S and KT48SVPRK sine wave controller.

    Hey all, I am deep in the guts of my controller and LCD8S display attempting a fix and thought it worth a shot to see if anyone here has anything similar and what they did to fix it. I have a new LCD8S display on the way as I think the issue is there, but it takes about a month from China so I...

    new cyclone 3000 w mid-drive kit?

    Does anyone have a link to this mount? I would appreciate it. Looking to tension my cyclone without a tensioner as that seems to fail every so often.

    Cyclone 3k and KT 60A Controller with LCD8S Problem

    Please don't mess with the hall sensors. I have read somewhere that most people do them unnecessarily and it is rarely the cause of these kinds of issues. This motor and controller combo is unique. The hall sensor wire colors don't line up with the phase wires, the yellow and blue hall sensor...
