6SE9210-7BA40

The Siemens part number 6SE9210-7BA40 is a variable frequency drive, classified under the MICROMASTER series. Designed with a compact frame size A, this unit employs V/f (voltage/frequency) control for enhanced performance tailored to motor drives. This variant connects through an RS-485 communication interface, facilitating effective system integration.

For electrical specifications, it operates on a single-phase input voltage of 200 to 240 volts AC (with a tolerance of ±10%), delivering a three-phase output voltage that reaches up to 240 volts AC. The drive is capable of a nominal output current of 0.75 amps, with maximum continuous current reaching 0.9 amps. It supports a wide output frequency range of up to 400 Hz, contributing to its versatility in various settings.

Cooling is managed through a controlled fan system, ensuring efficient operation even during demanding conditions. The overload capacity allows this unit to sustain 150% of its rated capacity for up to 60 seconds, which is advantageous in high-demand situations. The device is mounted on a DIN rail, which provides convenient installation in control panels and cabinets. With an operational temperature range of 0 to 50 degrees Celsius and a humidity tolerance of 5% to 95% non-condensing, this drive is suitable for many diverse environments. Its IP20 protection rating indicates a design that is protected against solid objects larger than 12.5 mm, making it ideal for indoor applications where environmental conditions are controlled.
