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.

Features Include:


Power MOSFET design, providing
infinitely variable drive and plug brake control
silent high-frequency operation
high efficiency (for reduced motor and battery losses)
Compact size
Overvoltage and undervoltage protection
Thermal protection and compensation circuitry provides undertemperature cutback, constant current limit, and linear rollback in overtemperature - thus preventing sudden power loss regardless of thermal conditions
CURTIS 1313-4331 Handheld Programmer (optional) provides a full set of parameter and function settings, as does the CURTIS 1314 PC Programming Station (optional)
Diagnostic and test information for the controller - and other system components - readily available both on-board and through the programmer
On-board potentiometers allow direct manual adjustment of acceleration rate, creep speed, maximum speed and plug current
Circuitry and software detects faults in the throttle circuit, MOSFET drive circuit, MOSFET transistors, contactor drivers, and contactors - ensuring that the controller meets EEC fault detect requirements
Input sequencing options include neutral start and static return to off (SRO)
Microprocessor-controlled contactor sequencing provides true arcless contactor switching
Smooth, controlled plug braking - with either variable (throttle-dependent) or fixed plug current limit
Neutral braking option provides automatic plug braking in neutral
MultiMode™ input selects between two different operating modes, thus allowing optimization of vehicle characteristics for different driving conditions
Emergency reverse (belly button switch) with a single input Ramp-start feature provides full power for starting on ramps
Simple contactor and switch wiring, with coil drivers monitored for faults - thus ensuring fail-safe operation
Flexible throttle circuitry accommodates a variety of throttle types
Programmable "ramp shape" (static throttle map) provides flexibility in selecting throttle response feel
Connections made by solid copper power busses with a polarized Molex connector for control signals
Solid, well-protected construction - with an aluminum mounting plate and injection-molded cover.
