SKB3400055 Control Techniques Emerson Nidec Drives 0.55KW 3P 380-480V
The Control Techniques SKB3400055 is a versatile and high-performance AC variable frequency drive (VFD) from the acclaimed Unidrive SP series, now part of Emerson’s industrial automation solutions. Rated at 5.5 kW (7.5 HP) with a 380–480 V, 3-phase input, this compact drive delivers advanced motor control for a wide range of applications—from conveyors and pumps to packaging machines, test rigs, and small machine tools.
As a member of the Unidrive SP family, the SKB3400055 supports multiple control modes in a single hardware platform: open-loop V/f, sensorless vector (SVC), closed-loop flux vector, and even servo-class positioning when used with optional encoder feedback cards. This flexibility makes it ideal for both basic speed control and demanding motion tasks requiring high dynamic response and precision.
Housed in a space-saving IP20-rated chassis, the SKB3400055 is designed for DIN rail or panel mounting and includes essential features such as integrated Safety Torque Off (STO), a built-in programmable logic controller (PLC), and standard Modbus RTU communication—all contributing to reduced system complexity and lower total cost of ownership.
