Elmo Motion control (Westford, MA) offers the “Whistle” digital servo drive with up to 500 watts of continuous power at 99% efficiency. The device weighs 1.76 ounces and measures 2 × 1.8 × 0.6". It interfaces to brush DC, brushless PM, and linear and/or voice coil motors. Power is provided by an external 7.5 to 95 VDC isolated DC power supply. A supply control algorithm enables the device to operate with one power supply.

altSeven models offer voltages and current levels from 1 amp, 60 volts to 6 amps, 100 volts continuous operation. The drive incorporates the control capabilities of the SimplIQ family of drives that offers feedback options, programming capabilities, communications protocols, and controlled motion technology.
