The nominal power draw on my 24v bow thruster is 500 A. Generally only used for about 30 seconds at a time, which is within the 600A intermittent range. However, if the BatteryProtect does trip, seems that it takes 90 seconds to reconnect. In a tight mooring situation with side winds, this is obviously completely unacceptable, and thus I should not install this unit.
Is my conclusion correct or have I misunderstood something here?
Hi @Meshugga
Where did you read it can withstand 600A for that long?
I did find that it should reconnect after 30 seconds:
"Load reconnect delay 30 seconds" but maybe it has to cool down first after the overload?
I wouldn't use a 220A device for such high current that has to be sustained if needed. I'd connect the battery directly and use a Battery Protect output to the control relay so it disconnects the relay signal instead of the high current path.
HI Daniel. Thanks for the response.
Got my info from the datasheet:
* Peak current (during 30 seconds) 600A
* Load disconnect delay 90 seconds (immediate if triggered by the VE.Bus BMS)
* Load reconnect delay 30 seconds
A question on your recommendation: How would the BP activate if it is only connected to the small control relay current? Seems to me it is essentially just a circuit breaker.
