(1) Extended fault detection and protection. The LED flashing pattern indicates the fault
sources .
(2) Monitoring battery voltage . It will s top driving if the battery voltage is too high and i t will
progressively cut back motor drive power as battery voltage drops until it cuts out
altogether at the preset “ Low Battery Voltage ” setting.
(3) Built-in current loop and over current protection.
(4) Configurable m otor temperature protection range.
(5) Current cutback at low temperature and high temperature to protect battery and controller.
The current begins to ramp down at 90 ﹾ Ｃ case temperature , shut ting down at 100 ﹾ Ｃ .
(6) The controller keeps monitoring battery recharging voltage during regen erative braking,
progressively cutting back current as battery voltage rises then cutting off regen altogether
when voltage goes too high.
(7) Maximum reverse speed is configurable to half of max forward speed .
(8) Configurable and programmable with a host computer though RS232 or USB. Provide free
GUI which can run on Windows XP/2000, Windows 7 and Vista(recommend using Kelly
Standard USB
To
RS232 Converter).
(9) Provision of a +5 volt output to supply various kinds of sensors, including Hall effect type.
(10) 3 switch inputs which are activated by connection to Ground . D efault to throttle switch,
brake switch and revers ing switch. Clos ing to ground is to activate.
(11) 3 analog 0-5V inputs that d efault to throttle input, brake input and motor temperature input .
(12) P ulsed r everse alarm output.
(13) Main c ontactor driver. Cut ting off the power if any fault is detected .
(14)Current meter can display both drive and regen current. Save shunt!
(15)Configurable b oost switch . Enables the maximum output power achievable if the switch is
turned on.
(16)Configurable economy switch . Limit s the maximum current to half if the switch is turned on.
(17) Maximum reverse power is configurable to half power.
(18)Enhanced regen brake function.
A
novel ABS technique provides powerful and smooth
regen.
(19)Configurable 12V brake signal input, instead of motor temperature sensor.
(20)Optional joystick throttle.
A
bi-symmetrical 0-5V signal for both forward ing and reversing
(21) Configurable motor over-temperature detection and protection with the recommended
thermistor KTY83-122.
(22)3 hall position sensor inputs . Open collector, pull up provided.
(23) Optional CAN bus.
(24)Optional supply voltage 8- 3
0V.
Caution!

Caution! Regeneration has braking effect but does not replace the function of a mechanical
brake. A m echanical brake is required to stop your vehicle. Regen IS NOT a safety feature!
Controller may stop regen , without warning, to protect itself or the battery ( it won
’
t protect you!).
