    ULtra Compact 1800W charger + Eltek programming

    I have 4 "FLATPACK2 48/3000HE G2" | Revision: 2.3 | SW: 1.01/2.01 using the arduino code i am able to set the default voltage and change the voltage and current on the fly. when the power supply is in CC mode it works but only to a minimum voltage of 47V. if I increase the load the voltage...

    Reading data from my sabvoton controller

    i think the adruino needs to send the start code to the controller on startup. and maybe you can add the reverse wire to the controller. I map out the wireing on my controller in this post: https://endless-sphere.com/forums/viewtopic.php?f=30&t=56378&start=25#p1337210 hope this helps

    Active pre-charge/inrush control

    in my build log there is some more info. https://endless-sphere.com/forums/viewtopic.php?f=12&t=83316#p1291037 so the chip is a LTC4252 Hotswap controller used a LR8 as a constant current soure to power the LTC4252 the current source is better than a fix resistor for use with a big voltage range.

    Reading data from my sabvoton controller

    my controller has a wire to change the motor direction. you can switch that wire with the arduino. i don't know if the system status changes when in revers. maybe check that with the pc program

    Active pre-charge/inrush control

    I used a linear tech part for my inrush limiter. cant recall the part number right now. it a chip controlling a low side mosfet with a current sense resistor. Used a constant current source ic to supply the LT part because it uses a internal zener. could post a schematic if there is interest. Manny

    150A BMS "blown" at 110A during lab test. Video attached. What next?

    you are confusing the voltage across the mosfet and the battery voltage. when the mosfet is on and conducting 14A @ 1.7m ohm x 1.5(150 ºC) voltage Vds = 35.7mV I do not see a obvious reason for the failure edit: what is the gate voltage?

    help sabvoton 72200 meltdown!

    just open it up! than we can see what is dead. replacement parts are probably best sourced from digi-key, mouser or similar good luck

    For Sabvoton sine wave motor controller users

    does your hall connector have a 6st wire? if so connect a 10k ohm resistor between that wire(Yellow-white) and the ground wire(black). the controller will think your motor is 25 °C all the time. good luck

    Help with Sabvoton and USB ($20 PayPal reward!)

    the baudrate will probably be the same. i think my controller has a empty spot on the PCB for a rs485 converter chip.

    Help with Sabvoton and USB ($20 PayPal reward!)

    have you tried to flip the green and white wire? if it is rs485 you will need a other converter. can you open up the controller to check if there is a rs485 converter chip?

    Help with Sabvoton and USB ($20 PayPal reward!)

    i whas thinking about this type of sabvoton. so lets try again. check the connections between the "USB" and the connector going in the sabvoton. if the ground is broken the serial com's will not work

    Help with Sabvoton and USB ($20 PayPal reward!)

    you can check the ground connection from the "USB" connector to the plug on the sabvoton side. the ground connection connects to pin 1. 5 volt is on pin 2 . USB white is on pin 7. USB yellow is on pin 6 if there is a brake in the ground line, you can use any other ground wire. from the...

    Speed controller and motor wattage

    the 500 watt of the motor is the max, so driving it with a 350 watt controller is on problem. the sine controller make less noise and can be smoother.

    Help setting up Sabvoton and QS-205

    there is no connection between you laptop and the controller. in the video i see only the tx "led" blinking on the software, and not the rx meaning the software is sending data but not getting a response. to find the correct serial port. open the device Manager on the laptop, open the tab...

    AC clamp current sensor on DC?

    depends on the sensor tech. if it uses a current transformer no you can't use it on dc if it uses a hall effect sensor, it might work
