Electromen EM-101 DC-motor control unit 12-24VDC 3A 4-quadrant

EM-101 is designed for modern automation systems. Controls can be performed easily with relay- or open collector outputs. Analog control inputs work with positive voltage. Usable motor can be permanent magnet motor with brushes in power range of 5...70W. Due to the pulse width modulation (PWM) the unit operates with high efficiency, low temperature losses and provides a high motor starting torque. Loading of the motor can be compensated with inbuilt RI-adjustment. The current, or in other words, the torque of the motor can be controlled with DIP-switch. The operation of the current limit is indicated with a red LED.

There are a variety of braking options available in this device. For most effective braking “reverse braking”-mode can be used. In this mode reversed driving is used for braking the motor, which archives extremely fast braking. Additionally the card utilizes short circuit braking which short circuits the motor circuit during the braking. EM-101 also has inbuilt settable time acceleration- and braking ramps.
