HA61GD-3B30

The HA61GD-3B30 is a dual channel fast precision high voltage amplifier with integrated signal generator in a 19" rack mountable case. This single channel amplifier provides output voltages of -3000V to +3000V at ±30mA (static) and 40mA_P (dynamic). The dynamic output current is available for signal frequencies down to 1Hz. The amplifier features high precision, high stability and low noise. It is suitable to drive capacitive and resistive-capacitive loads. The output is stable with any capacitive load and also stable at no load conditions. It can easily drive loads like Piezo elements, EAP actuators, electrorheological fluid elements, electrostatic deflection electrodes and many other loads. A differential ±10V amplifier input prevents any ground loops and provides excellent noise suppression. The maximum output current can be limited to programmable values and programmable behavior. Internal high voltage sources feed the output stage. The output stage is protected against overload, short circuit, over temperature and high voltage arcing. The amplifier outputs are made available via SHV high voltage connectors. A safety interlock circuit is provided to integrate the unit into an emergency shutdown circuit.
A command interface is available via USB and Ethernet interfaces to control the amplifier. Monitor values of output voltage, output current as well as internal operational parameters can be read.
An implemented DDS/ARB signal generator is provided to generate standard waveforms like sinewave, trapezoid, squarewave, pulse, sawtooth and noise as well as fully arbitrary waveshapes. Parameters are controllable via the command interface.
