Powerlab 8 questions
I am using a Powerlab8 V2 connected to a Efuel 1200W power supply set at 30 volts.
A couple of weeks ago I turned the powersupply on and got a OCP error and the powerlab would no longer even come on. Called FMA and then sent me a new powerlab 8 no questions asked. Which was great but Friday night the same thing happened. I guess I have 2 questions here. First has anyone else had this issue with the same combination and do I need to get a different powersupply? Second all I can figure out is both times it happened I had batteries connected to the MPA parallel board when I turned on the powersupply. I can't find anything in the manual that says don't do this but just looking for some answers at this point. Any thought or suggestions would be greatly appreciated. Thanks. |

This is what I know about that supply. https://www.helifreak.com/showpost.p...4&postcount=18
Regarding having packs connected to the charger at the time of power up, FMA says it will not harm the charger. But I know that it will damage other brands of chargers. As a best practice, I make sure the packs are disconnected from the charger before powering it up.

thanks
Thanks for the response.
I have the newest version of the powersupply with PCF. It actually runs really well on my 2000 watt generator. I checked the voltage output of the powersupply and it is right on 30V so It really does not seem like the powersupply is the issue. |

This just in. For that supply be sure to power up the supply before connecting the charger. This only applies to the eFuel supply.

thanks.
I spoke with Howard at FMA on Tuesday and he told me what the issue was. I guess the voltage spikes were causing the problem.
I am switching to a different powersupply. Not worth the risk for me. Thanks for the info. |
