Low voltage DC / battery powered high voltage amplifier WMA-02
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.
- High voltage 20x amplification up to +175V and -175V with respect to ground
- DC to 13kHz full-power bandwidth (-3dB) WMA-02
- DC to 50Hz full-power bandwidth (-3dB) WMA-02LF
- Low output noise: <4mVrms for the WMA-02 and <0.2mVrms for the WMA-02LF typical
- Continuous short-circuit protection
- No overshoot with capacitive loads and perfectly stable
- 100kOhm input impedance
- 50kOhm output impedance
- 50x100x26mm size
- 24V - 30V single DC power supply, 120mA max
The WMA-02 MEMS amplifier is very modestly priced: EUR 390,- (EU price) excl. VAT.
