DSP-354 microstep driver can drive any 2-phase hybrid step motor (current below 3.5A) with 40VDC/29VAC input voltage and 3.5A output current. This product adROPts sine save current control technique, which can make the motor running stably and with low noise. It is particular useful in application with high precision, small size numerical control devices, such as laser cutter, numerical controlled machine tool.
High performance, low cost
Low motor noise
Supply voltage up to 40VDC/29VAC
Peak value of output current up to 3.5A
Automatically idle-current reduction
Suitable for 2-phase step motor with 4, 6, 8 lead under 3.5A current
optical isolated input signals
8 selections for current setting
Over-voltage, under-voltage and short-circuit protection
Convenient for installation with small size
