Miniature Analog Amplifier for Extreme Environmental Conditions
Current mode servo amplifier for trapezoidal commutation
Although highly compact, the Robin can withstand extended environmental conditions and can 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 Raven is a PCB mounted device that enables efficient, cost saving implementation. |
