DC Whistle

DC Whistle Digital Servo Drive

Ultra-compact panel-mounted drive

The DC Whistle is a super compact OEM panel mounted version of the Whistle, which enables fast and easy mounting and implementation. This intelligent, digital servo drive is designed for DC brush and brushless motors, linear motors and voice coils. It weighs just 273 g (only 9.6 oz) and supports up to 20 A of continuous current. Its high density enables the drive to deliver 3.3 kW of peak power and 1.6 kW of continuous power. Based on Elmo's SimplIQ Motion Control technology, the DC Whistle is capable of operating in position, velocity and current modes and it offers a wide range of feedback and I/O options. With Elmo's Composer software, users can easily perform drive setup, configuration, tuning, analysis and programming. The drive operates on DC power.
