Introduction

The  PSD79AC-2P is one of the few Direct-On-Line Step Motor Drive, available in the industry, which can be simply power up from the AC power source without the need of a Power Supply.  This makes it cost effective and space efficient.  With a higher voltage input, this high performance bi-polar two phase micro-stepping drive is able to excite a motor size from Nema 23 up to Nema 42.  It can drive 2 Phase hybrid motor, that comes in 4, 6, or 8 leads.

With an automatic optimization speed control technique, the PowerStep series drive output is very stable, with almost zero vibration and noise, performing close to a servo system,  allowing the motor to operate smoothly. That helps to fulfill a design requirement of low noise, low heat and high performance.
