Good day, the 4840 was designed for use with a Vanner inverter, and since the inverter does all the rectification, that alternator has no diodes or recitifiers, will make only a/c current. Look at our part number 4420JB, that is rectified and is set to 56 volts, but only 85 amps. If you still have questions maybe call our tech service line, thanks.

Thanks for reply. Please advice:

- 4420JB is stated 48V - 85A in your website: http://www.prestolite.com/pgs_products/specs.php?item_detail_id=34386&it...

If we want to buy 4420JB of 56V, how we should specify?

- Weather you will supply modified 4840 with internal retifier 110A and regulator 56V if we insist in alternators of 56V - 110A and considering quantity of 1000 units in first year

- From whose we should buy some units for our prototype product and if we can be Prestolite distributor in Viet Nam as we buy for reselling here.

Good day, I don't know if we can get 110 amps out of a 56 volt alternator, I doubt it, usually as the volts go up, the amps come down. The best place for you to start at will be with the salesman for VietNam and his contact info is below. Thanks
