2.2 Features
1) Opto-isolated technology achieve stability.
2) Intelligence with powerful microprocessor.
3) Synchronous rectification, ultra low drop and fast PWM to achieve very high efficiency.
4) Electronic reversing.
5) Voltage monitoring on 3 motor phases, bus, and power supply.
6) Voltage monitoring on voltage source 12V and 5V.
7) Current sense on all 3 motor phases.
8) Current control loop.
9) Hardware over current protection.
10) Hardware over voltage protection.
11) Support torque mode, speed mode, and balanced mode operation.
12) Configurable limit for motor current and battery current.
13) Low EMC.
14) LED fault code.
15) Battery protection: current cutback, warning and shutdown at configurable high and low
battery voltage.
16) Rugged aluminum housing for maximum heat dissipation and harsh environment. Support
fan or water cooling.
17) Rugged high current terminals, and rugged aviation connectors for small signal.
18) Thermal protection: current cut back, warning and shutdown at high temperature.
19) Configurable 60 degree or 120 degree hall position sensors.
20) Support motors with any number of poles. Up to 40,000 electric RPM standard. Optional
high speed 70,000 ERPM, and ultra high speed 100,000 ERPM.
(Electric RPM = mechanical RPM * motor pole pairs).
21) Support three modes of regenerative braking: brake switch regen, release throttle regen,
0-5K or 0-5V analog signal variable regen for KHB and HP controllers.
22)Configurable high pedal protection: the controller will not work if high throttle is detected at
power on.
23) Current multiplication: Take less current from battery, output more current to motor.
24) Easy installation: 2 or 3-wire pot, or hall sensor throttle can work with KHB and HIP
controllers.
25) Remote fault code LED driver.
26) Current meter output.
27) Standard PC/Laptop computer is used to do programming. No special tools needed.
28) User program provided. Easy to use. No cost to customers.
