LAD-300S Series Intelligent Linear Servo Amplifiers

Varedan LAD 300S series are compact 4 axis digital linear current amplifiers designed to drive up to 4 single phase loads such as brush-type motors or voice coils. They are the perfect choice for systems requiring low radiated noise, zero distortion and low drift from the drive electronics. It is powered by a single external 15 to 56 VDC unipolar bus. With true class AB linear output stage (as opposed to PWM, pulse width modulation), the amplifiers are extremely quiet and provide very low distortion for smooth motor operation.
A 20 MHz salve SPI interface is designed to receive up to 4 channel digital current references. 4 channel 16-bit DAC with full resolution converts the digital current references to analog current commands.

The design of these amplifiers includes an on- board 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. A 7-segment LED display provides a visual indication of system status.
LA 310 has 4 current loop gain settings, selectable via front edge DIP switch. Customer can utilize this feature to drive 4 different loads or drive one load with 4 different bandwidth settings.
Varedan offers 3 different module packages, module, DC standalone and AC standalone. Standard module is an excellent selection for OEM applications. DC standalone module has a full covered enclosure with a cooling fan integrated. AC standalone integrates a 300W linear power supply and 2 cooling fans into the package, in which 110/240VAC power can apply directly.
