Feature:1. POWER SUPPLY AND CURRENT: Stepper motor use DC 10V45V. It is recommended to use switching power supply DC32V, which can be rated up to 4.5A, to meet the needs of your various applications2. AUTOMATIC HALF CURRENT FUNCTION: The driver board is equipped with automatic half current switch, easy to use, and set the output short circuit protection function, worry free to use3. OPTICAL COUPLING AND HEAT DISSIPATION: Stepper motor controller adopts 6N137 high speed optical coupler to ensure high speed without losing step. Increase heat sink, with good heat dissipation4. EASY CONNECTION: The driver board adopts a common positive input mode, with two input terminals, more convenient connection5. NOTE FOR USE: Instructions for subdivision settings are printed on the back of the control panel. The power supply should not be reversed; otherwise the chip will be burned out. The current set should not exceed the rated current of the motorSpecification:Item Type: Stepper Motor Drive BoardWorking Voltage: DC10V-45V. Switching power supply DC32V is recommendedOptical Coupling: Using 6N137 high speed optical coupling, ensure the high speed without losing stepShort Circuit Protection: Adopt the high current and high voltage for TB6600HG original chip launched by for Toshiba, which has low voltage turn off, overheat stop and overcurrent protection circuit, and short circuit protection with increased force compared with for TB6560Rated Output: Up to 4.5ASuitable: For 42, 57, 86 two phase, four phase, four wire, six wire stepper motor within 4.2AAutomatic Half Flow Function: YesSteps: Fine whole step, half step, 1/4 step, 1/8 step, 1/16 step, big 16 subdivision.Package List:1 x Stepper Motor Drive Board
