The Falco Systems WMA series consists of a range of high voltage laboratory amplifiers with industry-leading specifications. We have high voltage amplifiers available with extremely wide bandwidth (DC to 5MHz) and high speed slew rate (2000V/us), but also with ultra low noise (50 microVolt rms in DC – 100kHz). These specifications make the different amplifiers of the range an excellent choice for use with MEMS devices, EO-modulators, PZT positioning systems, beam steering components, ultrasonics, and in many other applications.

高速位相反転器 - バッファー WMA-IB-HS

The WMA-IB-HS can be used to double the output voltage of two high voltage amplifiers by driving them in bridge mode, or as high impedance input buffer while maintaining precision, high speed and low noise. Because of its high bandwidth, the WMA-IB-HS model is ideal for the Falco Systems WMA-100 or WMA-300 amplifiers. It can also be used with all other Falco Systems HV amplifiers, or even with high voltage amplifiers of another brand.
Specifications:
  • One BNC input, one BNC buffered output, and one BNC phase inverted output
  • High speed: DC - 20MHz @ -3dB full power bandwidth and -10V to +10V maximum output voltage
  • Switchable 50 Ohm /100 kOhm input: buffer low-current signals to drive high-speed 50 Ohm amplifier inputs
  • Power supply adapter accomodates both 230V/50Hz and 115V/60Hz mains voltage
  • Lead-free, environment-friendly construction
In bridge mode, the phase inverter - buffer can double the maximum output voltage available to drive a load such as a piezo actuator or electro-optical (EO-) modulator. The arrangement is show in the photograph and the schematic above. The phase inverter - buffer drives the two HV amplifiers with the same signal but opposite polarity. The load is connected between the two amplifier outputs, instead of the usual connection of the load between the output of an amplifier and ground.

バッテリ駆動の高電圧アンプ

Falco Systems provides a range of battery powered high voltage amplifiers, which can be used e.g. with floating power supplies or in a Faraday cage. They also serve as excellent cost-effective small stand-alone amplifiers.
These tiny high voltage amplifiers run from a low voltage 24V DC power supply or battery and provide a bipolar high voltage at their output. The WMA-02 delivers -175V to +175V, the WMA-01 -125V to +125V, while the WMA-005 covers the low voltage end of the range, with -75V to +75V output voltage.

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.
