A0014420JB - High Output Alternator

Hi,

I'm looking for alternator 48VDC 75A for an engine driven charger for 48V battery.

I found in your website that model A0014420JB can meet my requirement. However, since I require stable 48V voltage, I want to use a regulator.

Can you advice a regulator to maintain stable voltatge?

Regadrs,

Dear sir,

To charge 48V batteries you would normally need a 56V alternator (4420JB). Please can you confirm actual battery voltage required?

Our 4417JB is a 48V / 90A alternator and is supplied with a regulator set to charge at 48V, however this is not normally enough to charge a 48V battery bank (4x 12V batteries).

Best regards,

I confirm the 48 voltage need.

Why is the 4417JB alternator not enough to supply 48V?

Hi,

I confirm the 48 voltage need.

If the 4417JB is able to provide a stable 48v it's what I'm looking for.

Can you provide a datasheet of the 4417JB and also let me know how to order it.

Dear sir,

48V batteries are not actually 48V, technically they operate at 56V. It is a historical general terminology vs actual variance.
Many years ago when 6V batteries where used they were in reality closer to 7V. Then when technology moved to "12V" batteries, actual voltage is 14V, same again for "24V", actual operational voltage is 28.0V. Likewise "48V" is actually 56.0V. Hence my original question re 48V / 56V.

The 4417JB is designed for operation with an inverter, hence 48.0V voltage set point. The 4420JB is designed for battery charging, hence 56.0V.
