The level of international common feature of RS-232 control, compatible with compatible with Crestron, AMX, Lamar and other control system or a third-party control equipment; machine built 220V power supply, requires no additional power supply; built-in address code 255, according to different the system needs to be able to cascade 255; built eight imported 30A power relay module; extra wide outlet Dongguan generator SX440, free external power supply carriage; case of emergency control panel; power connector end has normally open and normally closed end SX440 , and other control modules can be linkage function; PC software control, the first device information access capabilities; save off state, power restored to the state again before the power failure; built-in RS-232 input and output interfaces to facilitate multiple Power Controller connection. When the electric vehicle controller brushless controller did not output a) referring to the main phase brushless motor controller check the measurement chart, with a multimeter DC voltage + 50V regulator board sx440 production profile, 6-channel MOS transistor to detect whether the gate voltage was transferred to the corresponding relationship between the rotation angle. 2) If there is no right, indicating that the controller in the PWM circuit or MOS tube drive circuit failure. 3) the main phase brushless controller reference checks, and whether or voltage measurement chip input and output pins and turn the rotation angle has a corresponding relationship, you can determine which chip is faulty, replace the same model chip can troubleshoot.
