(1) Extended fault detection and protection. LED flashing for fault code.
(2) Monitoring battery voltage. It will stop driving if battery voltage is too high. It will cut back
then stop driving if voltage is going too low.
(3) Built-in current loop and over current protection.
(4) Controller temperature measurement and protection
(5) Current cutback at low temperature and high temperature to protect battery and controller.
The current will ramp down quickly if controller temperature is higher than 90C, and
shutdown at 100C. Low temperature current ramping down usually starts at 0C.
(6) The controller keeps monitoring voltage during regen. It will cut back current then cut off
regen if voltage is going too high.
(7) Configurable to limit max reverse speed to half of max forward speed
(8) Configurable and programmable with RS-232. Software upgradeable. Windows GUI
provided.
(9) Provide 5V sensor supply
(10) 3 switch inputs. Close to ground to activate. Default to throttle switch, brake switch and
reverse switch.
(11) 3 analog inputs, 0-5V. Default to throttle input, brake input and motor temperature input
(12) Reverse alarm output. Recirculation diodes provided.
(13) Main contactor driver. Cut off the power if any fault detected.
(14) Current meter to display both drive and regen current. Save shunt!
(15) Configurable boost switch. Output the maximum current achievable if the switch is
enabled and turned on.
(16) Configurable turbo switch. Limiting max power to half if the switch is enabled and turned
on.
(17) Configurable max reverse power to half.
(18) Enhanced regen brake function. Novel ABS technique provides powerful and smooth
regen.
(19) Configurable 12V brake signal input, in lieu of motor temperature sensor.
(20) Optional joystick throttle. Single 0-5V signal for both forward and reversing.
(21) Motor over temperature detection and protection, with recommended thermistor.
(22) 3 hall position sensor inputs. Open collector, pull up provided.
(23) Optional CAN bus.
(24) Optional supply voltage 8V-30V.
Caution! Regeneration has braking effect, but can't replace mechanical brake. Mechanical
brake is required to stop your vehicle. Regen isn’t a safety feature! Controller may stop regen
to protect itself (not you!).
