Canary

Miniature Analog Servo Amplifier for Extreme Environmental Conditions

Current - mode servo amplifier for brush motors

The Canary is a series of miniature ExtrIQ current mode servo amplifiers for DC brush motors.Although highly compact, the Canary can withstand extended environmental conditions and support up to 25 amps continuous current. This high power density servo amplifier can deliver up to 5800 W of peak power or 2900 W of continuous power in a miniature package. The servo amplifier offers significant operating features including excellent output linearity and zero dead band performance. The Canary is a PCB mounted device that enables efficient and cost saving implementation.
