-DC limiting current
Take SVMC072150 for example, the limiting current is 150A,it means, under the enough battery capacity condition it can output 150A to the controller at maximum; The DC current will affect the climbing torque.
1, If there is no “3 various speed ”or “boost” in the controller, or these 2 functions are not valid , the “max DC current” is not effective, the rated DC current can be equal to the max DC current.
-----1)For controller with 60A as a limiting DC current ,the rated DC current is 20~60A.
-----2)For controller with 80A as a limiting DC current ,the rated DC current is 20~80A.
-----3)For controller with 100A as a limiting DC current, the rated DC current is 30~100A.
-----4)For controller with 150A as a limiting DC current, the rated DC current is 50~150A.
If “boost” or “3 various speed” function is required, the max DC current should be 50% higher than the rated DC current so as to get better performance.
-----1)For controller with 60A as a limiting DC current, the rated DC current can set 30A,while the max DC current set “60A”
-----2)For controller with 80A as a limiting DC current ,the rated DC current can set 40A,while the max DC current set “80A”
-----3)For controller with 100A as a limiting DC current, the rated DC current can set 50A,while the max DC current set “100A”
-----4)For controller with 150A as a limiting DC current ,the rated DC current can set 80A,while the max DC current set “150A”
-Phase current adjustment,
The rated phase current means the continuous current the controller can output. it can last for 3 minutes. If the outputting time exceeds 3 minutes ,controller will stop work because of overload protection, to get rid of this status, one need to turn off the power, and re-power up.
Normally, the rated phase current can set around 50% of the max working phase current.
The max working phase current means the max current the controller can output in a short period, it can last for 60 seconds, afterwards, the controller will stop work because of the block protection is on. to get rid of this status, one need to turn off the power, and re-power up.
Throttle max volt corresponds to the max phase current, the max phase current corresponds to the max torque output and it can affect the starting acceleration and climbing torque.
The recommended setting of max phase current for different models are as below,
-----1)For the controller with the limiting DC current 30~50A ,the rated phase current setting is 50~90A.The max phase current setting is 90~150A,the “protected phase current” is 180A.
-----2) For the controller with the limiting DC current 60~80A ,the rated phase current setting is 60~100A.The max phase current setting is 100~200A,the “protected phase current ” is 250A
-----3)For the controller with the limiting DC current 100~120A ,the rated phase current setting is 80~120A.The max phase current setting is 120~250A, the “protected phase current” is 300A
-----4)For the controller with the limiting DC current 150A ,the rated phase current setting is 100~180A.The max phase current setting is 180~350A,the “protected phase current” is 450A
(Remark: the above setting is for your reference. One can adjust the parameter as per personal preference)
