Isolation Amplifier
Option for Series A1110
Function#
The isolation amplifier has 3 channels: one for the input signal and one each for voltage and current monitoring. It is used wherever galvanic isolation between input and output signals is required, whether due to disruptive high common-mode voltage, to separate ground loops, or simply for safety reasons. Due to purely analog signal transmission, the output signal is free of clock and switching signals.
Due to the purely analog signal transmission, the output signal is free of clock and switching signals. The high offset stability is achieved by temperature control of the offset values.
This option has an effect on the bandwidth and slew rate of the amplifier.
Features#
- 3-channel isolation amplifier (input signal, voltage and current monitor)
- Input instrument amplifier with high common-mode rejection
- Wide small-signal bandwidth from DC to > 800 kHz
- Purely analog signal transmission, i.e., no switching signals in the output signal
- High offset stability is achieved through temperature control of the offset variables
- Isolates inputs and outputs up to 500 VAC / 1 kVDC
Applications#
- General lab applications for research, development and testing
- Universally applicable in scenarios with required galvanic isolation
- Galvanic isolation for personal protection, e.g. in medical engineering
- Galvanic isolation for safety reasons, e.g. for signal acquisition via computer systems
- Prevention of ripple pickup
- Measurement of small differential signals in high common-mode voltages
- Suppression of common-mode interference
- Actuation for series connection of amplifiers / power supply units
- Injection of interference signals in supply lines without transformer
- Design of automated test fields
