Ac Motor Speed Control 36v 48v 72V 80v current max 400A A5S For AC Motor controller
Product Description:
A5S series provide advanced control of AC induction motors and permanent magnet drive motors performing on-vehicle traction drive or hydraulic pump duties. They offer vehicle developers a highly cost-effective combination of power, performance and functionality.
The A5S series deployed with multiple patented techniques, that extend life of build-in relays and MOSFET units, a higher reliability is achieved.
The motor features vector control technology for magnetic field orientation and AC motor identification technology, enabling optimal torque control across the entire speed range.
Typical appication
Small and medium sized utility vehicles, lightweight road vehicles such as buggies, golf carts, low-speed electric car, pallet trucks and forklifts, etc.
Features:
Full Featured
