Technical Description: Nidec Control Techniques SKBD200150
The SKBD200150 is a high-reliability, compact AC variable speed drive from the Commander SK series. Designed for 200V class applications, this Size B drive provides a rated output of 1.5kW (2.0HP) with a continuous output current of 7.0A. The Commander SK series is world-renowned for its «Simple as it is» philosophy, delivering high-performance motor control in a package that is incredibly easy to set up and commission. It is an ideal solution for conveyors, fans, pumps, and general-purpose industrial automation.
Robust Performance and Integrated Features
Despite its small footprint, the SKBD200150 utilizes an advanced Open Loop Vector control algorithm. This allows the motor to produce high torque at low speeds and ensures stable speed regulation across the entire frequency range. The unit includes an integrated EMC Filter as standard, ensuring compliance with industrial emission standards without the need for additional external hardware. Its dual-rating capability allows it to handle 150% overload for 60 seconds, providing the necessary «breakaway torque» for heavy industrial loads.
