Trio Whistle - Integrated Triple Whistle Solution
Integrated Triple Whistle Solution

Elmo's TRW-WHI (TRW) is an integrated solution for X, Y, Z applications. A highly compact product, it combines three Whistle servo drive controllers in one package and operates using a single AC/DC power supply with a shunt regulator. The TRW-WHI is offered as two different models to provide maximum DC voltage of either 60 or 100 V. Both models support up to20 amps continuous current.

The TRW-WHI operates from an AC/DC power source in current, velocity, position and advanced position modes, with permanent-magnet synchronous brushless motors, DC brush motors, linear motors or voice coils. The solution is designed for use with any type of sinusoidal and trapezoidal commutation with vector control.
