Active Control Technology

ACT: Doosan exclusive AC control system
Performance Control: self-adjusts performance criteria to changes in operating conditions
Energy Control: maintains consistent performance through 80% of battery life
Comfort Control: customizes operating parameters to match driver’s style for increased comfort, confidence and productive control

OCDB – Oil Cooled Disk Brakes

EAB – Electrically Assisted Braking

Intelligent Instrument and Control Panel
Real time operating readouts
On Board Diagnostics

Removable panel for easy battery installation

12 volt lighting for longer bulb life

No delay or loss of torque during directional change

Superior Doosan AC Control

AC Control developed by SME
Advanced engineering company with extensive experience in developing and manufacturing AC controls
1ST company to introduce a complete AC control package

SME developed a special Speed Sensor

Dedicated Hall Effect Speed Sensor where the electronic circuit is separate from the bearing, resulting in lower working temperature, ease of replacement and increased operating life

Largest motors in the industry capable of producing superior horsepower, greater torque and longer running life

Travel Control

Magnetic steer angle sensor controls the travel speed while cornering therefore reducing the possibility of a tip over
Heat Control: system protects potential overheating situation, by gradually reducing performance until the detected temperature imbalance has returned to proper operating levels

Virtually Maintenance Free

AC Electric Motors
No commutator
One moving part with two bearings
Brushless

No directional or hydraulic contact tips – eliminates up to 11 sets on some models

ITC - Intelligent Torque Control

Closed-loop feedback system monitors load on drive and hydraulic motors to maintain constant performance, up to current limit, regardless of LOAD or INCLINE
Excellent gradeability and acceleration
Full protection against shorted or open circuits
Anti-roll back and anti-roll down with adjustable ramp stop time

Optimized Productivity

H mode [high performance]
S mode [standard performance]
E mode [energy efficiency]
Turtle mode [reduced travel speed while maintaining lift speed

SRO - Static Return to Off

Superb steering by maintaining RPM
Single line contactor and single drive fuse
BDI - Battery Discharge Indicator with adjustable lift interrupt and battery selection capabilities

DCB manufacturing process

Direct Copper Bond which uses clean room and special bonding technique
Removes thermal barriers between heat sink and transistor resulting in lower operating temperature
Faster communication time
Longer solid state component life
High current capabilities

SME Power Modules

Superior cooling capabilities with majority of models not requiring cooling fans

SME developed Intelligent Torque Control

Allows operator to use accelerator for speed and direct torque control as compared to speed control only
Faster torque response
Motor efficiency optimization in all operating conditions resulting in lower motor temperature and greater battery duty cycle
