Key Features

manufacturers of 2 phase stepper motor driver that has protection against overheating.
1.AC110v power input. Suitable for high-speed high torque applications.
2.Can specify driving current, reaching highest reading of 4.0A(SD245),6.0A(SD265) per phase.
3.Constant current bi-polar driving method, suitable for 4-lead-wire,6-lead-wire or 8-lead-wire 2-phase step motors.
4.Excitation mode can be selected from full-step or half-step.
5.Provide two methods of pulse input: Single-pulse(1p), and two-pulse(2p).
6.Can adjust running current and stop current for optimal motor revolving performance.
7.Overheating protection and output to ensure product safety.
8.Auto-current-down function for reduced motor heat.
9.Step zero output, and motor current off (cof) functions, can be used for external control.
10.Self-testing function.
11.High speed cpld component design, enhances stability of product.
12.Drive current using soft-up method to prevent sudden burn-out of driver.
13.LED displays revolving status. Input and output both use photo.
14.Coupler to provide noise isolation.
15.Special design of large aluminum alloy extrusion heat sink body.
