Castanet

Miniature, Ultra - Light Current Mode Analog Servo Amplifier

Ideal for trapezoidal commutation

The Castanet is a series of ultra-light current mode servo amplifiers for DC brush and trapezoidal brushless motors. Weighing only 0.76 oz (21.5 g), the Castanet can support up to 3.3 amps continuous current. This high power density servo amplifier can deliver up to 480 W of peak power or 240 W of continuous power.
The servo amplifier offers significant operating features, including excellent output linearity and zero dead band performance. The Castanet is a PCB mounted device that enables efficient, cost saving implementation.
