Hefei Huanxin Technology Development Co., Ltd. has been devoting ourselves to developing and manufacturing and other since 2004. We are located in Hefei, Anhui Province, with convenient transportation access. We employ over 101 - 200 People staff members. We have achieved great improvement since our company was founded in 2004. We abide by the motto of Firstclass quality, Reasonable price, Best service and Professional product support.

The 1228-2430 offers smooth, silent, cost effective control of motor speed and torque. A four quadrant, full bridge power output stage provides for solid state motor reversing and full braking power without additional relays or contactors.

The 1228-2430 controller is fully programmable, via the CURTIS Model 1313-4331 Handheld Programmer or 1314 PC Programming Station. This means the controllers can be tailored to the needs of specific applications. In addition to configuration flexibility, use of the programmer offers diagnostic and test capability.

Specifications:

PWM operating frequency: 15 kH
Electrical isolation to heatsink (min.): 500 VAC
Dielectric resistance: >1 MΩ (DC test)
Heatsink overtemperature: linear cutback starts at 92°C; complete cutoff at 134°C
Heatsink undertemperature: 50% armature current at -25°
Undervoltage cutoff: 14 V
Overvoltage cutoff: 34 V

Features Include:

Full bridge power MOSFET design, providing

infinitely variable forward, reverse, drive, and brake control
silent high frequency operation
high efficiency

Complete diagnostics through the CURTIS programmer and a status LED
Full compliance with all applicable international standards
Available for single-ended or wigwag 5kΩ potentiometer throttles and 5V throttles (both standard full stroke and restricted range)
MultiMode™ input selects between two different operating modes, thus allowing optimization of vehicle characteristics for different driving conditions (for example, indoor/outdoor)
Speed limit input provides linear variable speed limiting when an external speed limit pot is used
Current limiting in both driving and regenerative braking modes
Load compensation stabilizes speed on ramps and over obstacles
Speed scaler eliminates variations in maximum speed that would otherwise result from variations in battery charge levels
High pedal disable (HPD) function with lockout monitors status of the throttle during turn-on and prevents operation until the throttle has been returned to neutral
Key-off deceleration function provides a controlled deceleration if the keyswitch is turned off while driving
"E Stop" provides a faster deceleration for emergency stops
Seat lift function simplifies the wiring required to implement seat lift in DME scooter applications
Comprehensive fault detection monitors main contactor, output stage, throttle demand vs. output, etc., and disables the drive functions if any conditions are outside specified limits
ISO 7176 compliant throttle fault detection circuitry inhibits driving if throttle pot signal goes out of range for any reason
Missing/shorted brake detection forces neutral in the event of an open or shorted brake circuit
Anti-rollback/anti-roll-forward function sets brake delay according to speed and direction for improved braking response and minimized rollback on hills, etc.
Reverse beeper option can be used to drive a low current dc horn when vehicle is in reverse
"Push" input electrically releases brake for key-on pushing (requires that the vehicle be stopped first)
"Push-Too-Fast" feature guards against unpowered vehicle runaway by powering up and regulating motor voltage to limit vehicle speed
Inhibit input disables the controller and puts the vehicle in a safe state during charging, etc.
Power saver deactivates the main relay after 25 seconds of nonoperation and deactivates the entire controller after the programmed sleep delay has elapsed
BDI output can be used to provide data to a voltmeter; the BDI output can be "stuffed" (optional) in order to display the battery state of charge during battery charging even while the keyswitch is turned off
Undervoltage cutback function protects against operation at low battery voltage
Overvoltage protection shorts the motor and disables driving in the event of excessive battery voltage
Thermally protected
Reverse polarity protected (battery input)
Easily programmable through the CURTIS Model 1313-4331 Handheld Programmer or 1314 PC Programming Station.
