Three-Phase Frequency Converter 7.5Kw series S100 - LS

Three-phase frequency converter 400V 7.5Kw (10HP), integrated RFI filter and programming panel.

Frequency converters (VFDs) allow for the control and speed variation of standard three-phase motors. They are only suitable for connection to AC motors.

This frequency converter model already has a built-in RFI filter to prevent electromagnetic interference that could occur with other electronic components.

The front button panel includes all the necessary buttons for motor control and a potentiometer for speed regulation. It can also be controlled from pushbuttons and an external potentiometer.

Fixing can be done using screws to the mounting plate or using a DIN rail.

The S100 series incorporates "Safe Stop" function inputs and can be used in either "constant torque" or "variable torque" mode.

The maximum output frequency of the S100 series inverters is 400Hz. Special firmware is available to achieve 1000Hz, which is very useful for machine tools with high motor speeds. The frequency converter must be ordered with this firmware before shipment.

The LS brand S100 series of frequency converters incorporates:

• You enter the "Safe Stop" function.
• 5 Programmable speeds with activation via inputs.
• RS485 communication.
• Integrated RFI filter.
• Programming panel integrated into the front.
• Integrated braking unit.
• Constant torque and variable torque operation.
