Product Description:

The Kollmorgen's SMC-155 bipolar chopper micro stepping pulse and direction driver is made for complex motion applications that need precise control. The stepping pulse has a wide range of input voltages and micro-stepping options that the user can choose from. This makes it a flexible solution for automation processes.

The SMC-155 bipolar chopper micro stepping pulse and direction driver enables the selection of the step number to enhance performance customization and provide additional control options. The unit works reliably in both new and old systems because it is easy to set up and can handle high-power input. The micro-stepping pulse is compatible with input voltages of 115/230 VAC at 50 or 60 Hz and operates within the range of 90–240 volts, that provides a wide range of installation options for various electrical systems. The control inputs are optically separated to enhance signal integrity and noise immunity. This ensures that the driver is protected from electrical interference. The strong construction of this driver makes it reliable for a wide range of industrial automation tasks. This means that it works consistently and accurately in places where operational needs change.

The SMC-155 driver relies on a bipolar chopper micro-stepping driver design to improve torque and reduce motor resonance. The driver can handle accurate pulse and direction commands so that it can work with motion controllers in industrial automation systems without any problems. The micro driver provides full, 1/2, 1/4, 1/8, 1/16, 1/32, and 1/64 steps per pulse. Powerful motion control systems are compatible with the driver, as they are capable of managing currents of up to 10A. We at Wake Industrial guarantee fast order handling of the products and offer a one-year warranty for extra peace of mind.
