EM-243C Electromen OY DC Motor Controller, 12 → 48 V dc, 50 A, 12 V dc, 24 V dc

EM-243C DC Motor Controller_x000D_ EM-243C is a full bridge DC-motor starter. It is designed to work with DC-motor in applications where some special functions are needed._x000D_ Starter has adjustable acceleration and deceleration ramps, which make possible the smooth starts and stops. Adjustable current limit protects motor against overcurrent and it can also be used as an end-stop. This device has also two settable speeds, which are useful_x000D_ in positioning applications. Control inputs FW and BW start the forward and backward run. STOP is for the motor shut-down but there are also available individual limit inputs for FW and BW directions. SPEED-2 input activates preset speed-2, but it can also be used as input for analogue speed control signal 0-5V. FAULT terminal has at the same time input and output function, the pin is normally high, but is pulled down in overheat and conditionally also in current trip situation. If FAULT-line is pulled down externally, it will cause a stop and prevent the new start. For example, it is possible to link fault pins of several units together and achieve a synchronous stop. There are 2 selectable control modes, continuous and impulse. In continuous mode the motor runs as long as the control is active. In impulse mode a short command starts the motor, and only a new impulse will change the status._x000D_ Features & Benefits_x000D_ Small size_x000D_ High current output_x000D_ Current limit_x000D_ Zero current limit_x000D_ Speed setting_x000D_ Flexible control inputs_x000D_ Impulse / continuous mode_x000D_ Rail base mountable_x000D_ Digital parameter setting_x000D_ C version card compatible with A version card_x000D_ C firmware can be loaded A version card_x000D_ C version new features-_x000D_ + Freewheel options parameter_x000D_ + 2kHz or 16kHz pwm frequency selects_x000D_ + Current limit analogue input_x000D_ + Speed and direction operating mode_x000D_ + Fan and Brake available in board 243C v.2_x000D_ + Extend operating voltage in board 243C v.2_x000D_ Electromen - EM-243C DC MOTOR CONTROLLER, 12-42 V DC, 50A_x000D_ The EM-243C is a full bridge DC-motor starter.
