Key product specifications include a maximum and peak current output of 90mA and three factory-configured output voltage ranges (-30/150V, -30/200V, ±100V). The product’s bandwidth is greater than 5 kHz (-3 dB), and electrical noise on the output is approximately 2mV,rms. Circuit protection includes over-current, over-temperature, and short-circuit protection. The VF-90 has also achieved FCC and CE certifications for product safety and emissions/immunity.
The VF-90 is ideal as a single channel amplifier for use in open-loop, lower-power applications driving piezoelectric motion devices. Typical applications include optical fiber stretching, optical scanning, metrology, and proportional valve control.
