ELECTROMEN
Electromen - EM-176
DC motor 4Q drive 12-24Vdc, 10A
EM-176 is designed for DC-motor speed control. The unit can be used with unregulated DC supply. Motor
loading can be compensated with inbuilt RxI-type adjustment. EM-176 utilizes PWM driven H-bridge, thus
achieves high efficiency and extensive controlling options. Speed control value can be set with voltage signal
or with potentiometer, there is an auxiliary voltage signal output for potentiometer use. The scale trimmer can
be used to scale set value to correspond better the motor rpm. An auxiliary card can be fitted into EM-176 for
bipolar input controlling with voltage signal or potentiometer. The ramp feature is used to limit the motor start
and brake speed, in other words soften the operation and prevent the occurrence of current spikes. The
current limit limits motor torque that is current; this protects the motor and the mechanics. The unit has
separate inputs for brake, freewheel and reverse. Brake short-circuits the motor poles and produces powerful
braking. Freewheel detaches the power stage from the motor and leaves motor rotating freely. Reverse
changes motor rotating direction, this is done using the set ramp times. Brake and freewheel bypass the ramp feature.
FEATURES:
• 4 Quadrants
• Braking
• Freewheeling
• Reversal
• 0...10V control
• Optional ±10V control
• Soft start ramp
• Adjustable current limit
• Load compensation ( RxI )
