WMA-005 and WMA-005LF Low voltage DC / battery powered high voltage amplifiers

The Falco Systems WMA-005 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 3mVrms. For extremely low noise applications where bandwidth is not an issue, a dedicated WMA-005LF version is available that contains an output low pass filter capacitor which reduces the bandwidth to 50Hz, but makes the noise drop to below 0.1mVrms. This bandwidth-limited amplifier is ideal for MEMS or piezo positioning with manual voltage adjustment.

Specifications:
- High voltage 20x amplification up to +75V and -75V with respect to ground
- DC to 20kHz full-power bandwidth (-3dB) WMA-005
- DC to 50Hz full-power bandwidth (-3dB) WMA-005LF
- Low output noise: <3mVrms for the WMA-005 and <0.1mVrms for the WMA-005LF 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

The WMA-005 and WMA-005LF high voltage amplifiers are priced at EUR 495.- (EU price)
