EM-337A-48V PLI PARALLEL DRIVER FOR 4 ACTUATORS or MOTORS 24-48Vdc 4x8A / 4x15A peak

156,00 € /unit

EM-337A-48V-PLI is a parallel synchro controller for 4 DC-motors. The controller has four H-bridge power stages. The driver works with actuators that can offer pulse feedback signal. The control is done with FW / BW commands. The synchronization control will keep all motors in the same speed and position. If synchronous error exceeds the set difference limit, all motors will be stopped. Device includes adjustable acceleration and deceleration ramps, which produce the smooth starts, stops and direction changes. Load compensation also enables good operation with asymmetric loads. Adjustable current limits can be set to protect motor and mechanics against overcurrent (over sized forces).
