EM-A24-SPF DC-Motor Driver module With Positioning Pulse Feedback
EM-A24 is a DC-motor driver module, It's based on EM-241 driver card. This module is PCB mountable and it needs a very small pcb area, because it will be installed vertically. This module has effective H-bridge power stage. The power stage has low EMC emission and it can meet EMC directives for industry and household enviroments without external components. This is big benefit when integrated this module to the "motherboard".
Module has two pwm frequency option 2kHz offer more current, and 16kHz is noiseless.
