The Falco Systems WMA-02 is a high voltage amplifier

The output noise of the WMA-02 is impressively low, at

that runs from an 24 – 30V DC power supply and can be

only 5mVrms in the DC - 13kHz full power bandwidth. For

battery powered if required, e.g. for use in a Faraday

even lower noise applications where bandwidth is not an

cage. Its internal high voltage generator is inductor-free

issue, the WMA-13LF amplifier contains an output low pass

and hence does not spread magnetic interference in

filter capacitor. This reduces the bandwidth to 50Hz, but

sensitive experimental setups. Its large voltage range

makes the noise drop below 0.2mVrms. The bandwidth-
