Detailed Product Description

DC MOTOR CONTROL ASSEMBLY are composed of main contactors, reversing contactors, main circuit fuses, control fuses and Aluminum Heat Sink .

Technical parameter:

 Voltage use :Operating voltage of ± 25%

 Chopper frequency :50KHZ

 Input voltage electric locking : the same as system voltage

 Input current of electric locking : 60mA (typical value) 3 seconds boot time of about 350mA

Precharge

 Ultra-voltage protection :   Operating voltage of 125%

 Contactor drive voltage :    With the same operating voltage controller

 Contactor drive current :    2A (over-current protection 3A)

 applicable  Ambient temperature : -25 Degrees Celsius to 50 degrees  

Features:

 1.Built-in pre-charge resistance, polarity protection diode, to install, convenient to use.

 2.Under-voltage and over-voltage protection, effective protection of the battery and controller components assembly.

 3.Error correction operation of the order of protection, effectively prevent the operation of the .driver due to errors caused by electrical damage to vehicles running on the Elimination of insecurity.

 4.Mute with the operating system, contactor pull-in, released by the MCU to control and eliminate the process of driving a vehicle frequently caused by foot accelerator moving contactor pull-in, the release of the noise.

 5..90 seconds no acceleration signal input, automatically disconnect the contactor coil electromagnetic power, saving battery power.

6. Work through the chopper state light-emitting diode, a direct diagnosis of the various components of the controller assembly fault source.

 7.Communication output interface, the fault diagnosis information can be sent to the combination of instruments (colla produced electric cars special instruments) to facilitate the source to find fault.

8.Stepless speed control and reverse brake.
