functions
(1) Extended fault detection and protection. LED flashing code indicates fault sources.
(2) Monitoring battery voltage. Stop driving if battery voltage is too high or too low.
(3) Built-in current loop and over current protection.
(4) Controller’s temperature measurement and protection
(5) Cutting back current at low temperature and high temperature to protect battery and
controller. The current will ramp down quickly if controller temperature is higher than 90
℃
,
and shut down at 100
℃
. Low temperature current ramping down usually starts at 0
℃
.
(6) Two RS232 ports. Both can be used for configuration.
(7) Configurable and programmable with RS-232. Software upgradeable. Windows GUI
provided.
(8) Provide 5V sensor supply.
(9)3 switch inputs: Default to throttle switch, brake switch and reverse switch. Closing to ground
is to activate.
(10) 3 analog inputs, 0-5V: Default to throttle input, brake input and motor temperature input.
(11)Reverse alarm output. Recirculation diodes provided.
(12) Main contactor driver. Cut off the power if any fault is detected.
(13) Current meter to display both drive and regen current. Save shunt.
(14) Configurable boost switch. Output can arrive at the maximum current if the switch is
enabled and turned on.
(15) Configurable turbo switch. Limit max power to half if the switch is enabled and turned on.
(16) Configurable max reverse power to half.
(17) Enhanced regen brake function. Novel ABS technique provides powerful and smooth
regen.
(18) Configurable 12V brake signal input, in lieu of motor temperature sensor.
(19) Optional joystick throttle. Single 0-5V signal for both forwarding and reversing.
(20) Thermal overload detection and protection to safeguard the motor from over temperature,
with recommended Silicon temperature sensors KTY83-122.
(21) Using battery-powered.
(22) Optional CAN bus.
(23) Optional supply voltage 8V-30V.
