Woodward|1751-147| MPU Isolation Transformer
Woodward 1751-147 MPU Isolation Transformer
Description
The Woodward 1751-147 is a 3:1 step-down MPU isolation transformer used to protect NI 9221 analog input channels from overvoltage generated by magnetic pickup (MPU) speed sensors in turbine monitoring systems.
Features
- Provides galvanic isolation for MPU signals
- Limits input voltage to safe levels for ±60 V rated inputs
- Compatible with high-frequency speed probe signals
Technical Specifications
- Turns ratio: 3:1 step-down
- Input voltage tolerance: Designed for MPU signals exceeding ±60 V
- Output voltage: Reduced to one-third of input amplitude
- Maximum signal frequency support: Up to 10 kHz
- Conductor compatibility: Works with 12 AWG to 24 AWG copper wiring
