LA-200/400/500 Series Linear Amplifiers
The LA Linear Servo Amplifier Series are the perfect choice for systems requiring low radiated noise and zero distortion. These high power linear amplifiers are well suited to drive loads such as brushless and brush servo motors or voice coils. Our designs incorporate class AB linear output stages for true linear output.
The design of these amplifiers includes an onboard high-speed DSP that monitors all key system functions in real time, and provides protection for the outputs by limiting output power to a “Safe Operating Area”. An intelligent user interface allows setup and storage of all system parameters via the serial interface. Non-volatile memory provides storage of the parameters during power off conditions.
Modes of Operation
In current mode the amplifier is commutated by an external controller. Our Linear Amplifier Series are designed to drive single & 3-phase loads by analog input commands.
These current mode linear amplifiers are available in the following standard configurations:
“T-Mode” – Three-phase current output. This configuration is used for driving three phase rotary or linear motors with a full-bridge output configuration. In this configuration the amplifier receives two sinusoidal current commands for phases A and B (ABSine). The phase C command is generated internally in the amplifier.
