General Specification
Model P403A is a high performance microstepping driver suitable for 2-phase and 4-phase hybrid steppers requiring a drive current of up to 3.5A / phase. The design features an advanced bipolar constant-current chopper circuit with current control technology. This driver is suited to stepper motor control applications requiring low noise, low vibration, high speed and high precision.
