Hengjiaan 4A Stepper Motor Driver Controller Board - Black + Green
Features: H-bridge bipolar constant phase flow drive Bipolar constant current chopper; High-speed optocoupler signal isolation input Electrical input signal is TTL compatible Stationary current is automatically reduced by half Suitable for any small-and-medium automatic equipment with CNC controller£¬ such as X-Y-Z tables£¬ labeling machines£¬ laser cutters£¬ engraving machines£¬ and pick-place devices. Description: Supply Voltage: DC 9~42V Input voltage: DC 12 ~ 48V Operating Temperature: -10 to 45'C Storage temperature: -40 to 70'C Max Drive Current: 4A Chopping Frequency: 20KHz 1£¬ the output current is infinitely adjustable to meet your various application requirements. 2£¬ automatic half current function. And a semi-automatic flow switch£¬ easy to use. 3£¬ the use of high-speed optical coupling 6N137 ensure high-speed without losing step. 4£¬ printed on the back panel are subdivided setup instructions. 5£¬ used to increase the heat sink£¬ good heat dissipation. 6£¬ output short-circuit protection£¬ the use of mind. 7£¬ using common anode input mode£¬ there are two input terminals£¬ wiring more convenient. Note: This driver is the upgraded version TB6600£¬ heightening segment to 32 subdivision£¬ suitable for high segmentation applications. For step motor: 42£¬ 57£¬ 86 type 2 phase 4 phase (4 / 6 / 8 line)
