WMA-100A high voltage amplifier

The WMA-100A model is our cost-effective, compact, general purpose high voltage amplifier. With its high quality and small form factor, it is the ideal choice for any experiment that requires an all-round, reliable high voltage amplifier. It can also be used as a stand-alone low noise high voltage power supply. Two WMA-100A amplifiers and a WMA-IB-HS phase inverter - buffer can be used to double the output voltage.

Cost-effective high voltage amplifier for MEMS and piezo's
- 20x amplification up to +170V and -170V output voltage (with respect to ground)
- DC to 500kHz at (-3dB) large signal bandwidth and 100 mA output current
- Low noise at ~840 uVrms in DC - 10MHz; even lower when capacitive loads are driven
- No overshoot with capacitive loads; bandwidth changes automatically to ensure stability
- Short-circuit protected output
- Adjustable DC offset control knob
- Available in a 230V/50Hz and 115V/60Hz version
- Lead-free, environment-friendly construction

The WMA-100A high voltage amplifier is priced at EUR 1325.- (EU price)
