WMA-02 and WMA-02LF Low voltage DC / battery powered HV amplifiers

The Falco Systems WMA-02 is a high voltage amplifier that runs from an 24 - 30V DC power supply and can be battery powered if required, e.g. for use in a Faraday cage. Its internal high voltage generator is inductor-free and hence does not spread magnetic interference in sensitive experimental setups. The output noise is impressively low at 4mVrms. For extremely low noise applications where bandwidth is not an issue, a dedicated WMA-02LF version is available that contains an output low pass filter capacitor which reduces the bandwidth to 50Hz, but makes the noise drop to below 0.2mVrms. This bandwidth-limited amplifier is ideal for MEMS or piezo positioning with manual voltage adjustment.
