Product description

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.
