Cymbal

Analog DC Current Mode Servo Amplifier

Ideal for DC brush and DC brushless for trapezoidal commutation

The Cymbal is a series of current mode servo amplifiers for DC brush motors and trapezoidal brushless motors that can support up to 90 amps continuous current. This high power density servo amplifier can deliver up to 13,600 W of peak power or 11,300 W of continuous power. The servo amplifier offers significant operating features, including excellent output linearity and zero dead band performance.
