The AT 4000 small series power stage features excellent control characteristics at competitive price. This product is covering a range of nominal power from 2.5 to 6 KW in three different models respectively rated for 3 / 5 / 9 Amps nominal.
Connect mains, use our easy setup and monitoring software and go!
Everything you need for a single or multi axis application is available in the AT 4000 series. Powerfull & Reliable IGBT output stage, integrated braking resistor, DC bus for enhanced braking power efficiency with multi-drives, STO (Safe Torque Off) safety functions as an option. Toghether with our control units many technology features and motor feedbacks are available without an extra charge. A separate DC-power supply is not necessary for operations. All necessary voltages for external periphery are internally made.
This product is virtually compatible with any rotary, linear, synchronous and asynchronous motors available. Please check our control units choose chart to see all our control feature range, we surely have the solution that suit your needs.
Reduce your costs with our versatile solutions!
