New: WMA-200 ultra-low noise high voltage amplifier

The Falco Systems WMA-200 model is a high quality, high voltage, linear laboratory amplifier optimized for experiments requiring world-class, ultra-low output noise. The excellent noise performance, combined with the wide bandwidth and large voltage range make this amplifier the preferred choice for the most demanding precision positioning systems. The amplifier will routinely enable sub-atomic positioning resolution with piezo positioning systems and MEMS devices. Two WMA-200 amplifiers and a WMA-IB-LN phase inverter - buffer can be used to double the output voltage.

Ultra-low noise high voltage amplifier for MEMS and piezo's
- Ultra-low output noise: ~50uVrms with DC - 100kHz large signal bandwidth; ~20uVrms with DC - 500Hz using the supplied load capacitor box
- High voltage: 20.0x precision amplification up to +175V and -175V output voltage with respect to ground
- Short-circuit protected output with 275mA output current capability
- No overshoot with capacitive loads: bandwidth changes automatically to ensure stability
- 2 inputs: a standard BNC connector, and a differential connector to reject interference (mating connector supplied)
- BNC monitor out connector provides 1:100 replica of the output signal
- Available in a 230V/50Hz and 115V/60Hz version
- Lead-free, environment-friendly construction

The WMA-200 high voltage amplifier is priced at EUR 1845.- (EU price)
