Motor voltage is regulated against supply voltage changes and there is also a load compensation (Rxl) adjustment. Thanks to these features, the EM-185 offers good performance in motor speed control applications. Current limit and Rpm range are adjustable with trimmer potentiometers. The power stage of the device is protected against short-circuit and overload. The unit is easy to mount in a 10 mm hole in an assembly panel. Materials and features meet the industrial environment requirements. The EM-185 is is EMC-tested, and is suitable for motors of 5-80 W. Electromen Oy Ltd , 20810 Turku, Finland. www.electromen.com.
