Product Description:
Dala A2 series offers advanced control of AC induction motors for on-vehicle traction drive duties, providing vehicle developers with a highly cost-effective portfolio of power, capability, and functionality.
The A2 series is equipped with multiple patented techniques that extend the life of built-in relays and MOSFET units, achieving higher reliability.
Features:
Full Featured
-
Offers a wide working frequency range of 0 to 300Hz.
-
Capable of delivering 300A output at system voltages ranging from 48V to 72V. These ratings are true 2-minute Arms ratings, not short-duration 'boost' ratings.
-
Supports regeneration braking, SOC algorithm, magnetic eddy current brake control, emergency stop-and-reverse motor control, and anti-sliding slope.
-
The Indirect Field Orientation (IFO) Vector Control algorithm generates maximum torque and efficiency across the entire speed range.
-
Enables quick and easy motor characterization without removal from the vehicle. A2 series controllers are fully compatible with any brand of AC motor.
-
Includes auto temperature compensation and remote calibration.
-
Utilizes Advanced Space Vector Pulse Width Modulation (SVPWM) techniques for low motor harmonics, low torque ripple, and minimized heating losses, resulting in high efficiency.
