¿Dónde comprar controlador potente?

oriam escribió:el comentario del paisano dice que tiene 100v mosfets y esos 20s, a mi lo que me fastidia son esos 15 mosfets, es mas largo que el de 12 y ya no me entra en la dichosa bolsa de triángulo

Para que te quepa todo. Lo mejor es una caja de fibra de vidrio en el cuadro.
Tiene su curro pero creo que merece la pena.

Leo Liu: Dear Jorge, sorry for my late reply! We used IRF4410FET, the controller can not withstand up to 100V for now. If you must use over 100V, the controller need to be customized, the lead time will be very long.

What is the voltage of the battery pack will you use?

Hello Jorge,

Sorry for my late reply!

We will make the controller with 15FET 4410's or 4110's, the controller can support to 100V, but can not over 100V, can you understand me?

Which battery pack will you use? If you use the battery pack over 100V, the 15FET 4410' and 4110's controller will not work properly. We have to use 4115FET, but we did not make this controller before, it will take much longer time I think.

We accept Paypal, not a problem.

Any questions, please feel free to contact me!

Best regards,

Leo Liu

"Hi Luis,

They're P75NF75 MOSFETS rated for 75V. Technically they're being run slightly over spec for a 72V SLA bank with a full charge. See this thread for full debate:"

Vamos que 75v por lo que no merece la pena

oriam escribió:Los 4115 originales (IR) son para mas de 100v, soportan 150v, lógicamente los que montan los chinos no son originales ninguno, valdrían mas que el controlador http://search.digikey.com/us/en/products/IRFB4115PBF/IRFB4115PBF-ND/2096589 los 4115 originales en el lyen http://endless-sphere.com/forums/viewtopic.php?f=31&t=18605
Los que trae el controlador de serie se supone que son para 100v y los 4115 para mas

Si acepta paypal y trae esos Mofset parece viable ¿no?

Oriam, si quieres le puedo sugerir que se ponga en contacto contigo, o bien postee en el foro.

¿Y en que precio se movería?

¿de donde viene?

¿modo de pago se sabe algo?

The size of the controller box is 175mm*86mm*46mm, please check the attached photo with size and confirm if this size suitable for you?

If you need 180mm total, so we only can remove the fix hole at both sides (only remain controller box with end covers), is it ok for you?

Yes, we used 15FET 4410's, the voltage of the capacitors are at least 100V. The low voltage cutoff voltage can be set as your request, we usually set 63V lvc for 72V batteries, is it ok for you?

The limit current is 45Amax, is it ok for you?

We usually make universal model for 15FET controller, so the controller can work with both sensored and sensorless motor, suitable for you?

Any questions, please feel free to contact me!


Dear Luis,

Sorry for my late reply!

So for now the size of the controller box is not a problem for both of us. For the LVC, if we set it for 42V, is it ok for you? Do you need Regenerative braking charge ( when you pull the brake lever, the battery is full charged)? The Regen braking voltage is related to the LVC.

Will you order one sample for testing?

Any questions, please feel free to contact me!

Dear Luis,

Sorry for my late reply!

I think 15V LVC is possible, but I need to confirm it with the engineer again tomorrow, then inform you the news.

Any questions, please feel free to contact me!
