RD33771-48VEVM Max Load Current?

Choist — Mon, 04 Sep 2023 02:10:36 GMT

Hello I purchased and am using RD33771-48VEVM.

The load motor we are currently using is of the high current (70-100[A]) class, so I would like to know how far it can be used.

I want to know what the maximum load current is.

Thank you

This BMS part use the shunt resistor 100uΩ which can support test −1500 A to
1500 A (the actual range is in terms of voltage and is given by min and max of VIND) with
a 6.0 mA resolution.

So, is this model capable of using a motor load of up to +-1500[A]?

I'm afraid the cable might burn out.
