About the item

Overview:

The ST-M5045 is a cost-effective, high-performance bipolar two-phase micro-stepping driver, featuring PWM current control technology and superior performance over the M542/2M542/DM542 drivers, for applications requiring low noise and less heat. This helps to achieve low noise, low heat and high performance design requirements.

Features:

◆ PWM current control, two-phase sinusoidal current drive output;
◆ Supply voltage up to 50VDC;
◆ Output current peak up to 4.5A;
◆ When the motor is stopped, the current will be halved automatically to reduce the heating value of the motor;
◆ Can drive 4,6,8-wire two-phase, four-phase stepper motor;
◆ High-speed opto coupler isolation signal input, the pulse response frequency up to 300KHZ;
◆ Output current 1.5A ~ 4.5A;
◆ Output current setting is convenient;
◆ Small beautifully dimensioned
◆ Segmentation accuracy 2, 4, 8, 16, 32, 64, 128, 256, 5, 10, 25, 50, 100, 125, 250;
◆ Over-voltage, under-voltage, over-current protection.
