20VS1D

Hybrid IC Isolation Amplifiers 20 Series

ISOLATION AMPLIFIER

(top adjustment, for current output, output isolation)
Functions & Features
• Being used for printed wiring board installation
• Isolating between input, output and power
• Isolation between input and output up to 2000 V AC
• Power 15V DC
Typical Applications
• Isolating the fiels and output circuit of microprocessor to reduce common mode noise
• Available for manufacturers of small-lot products to omit the development of isolation circuit
