Description
Sentran Model 4DS-xxA:5VDC-xx is a 600 Vac rated AC current to DC voltage transducer
- The AC input current through the current transducer window is rectified and filtered to obtain a DC output
- There are 13 standard sizes are available, but custom made-to-order are always available to fit special applications
- Since internal passive rectifiers are used in the 4DS (no internal power supply), conversion to DC is true RMS AC sine waves only
- The output voltage is set to 2.5 Vdc at full-scale input
- Also, it is meant to be connected to high impedance
- There is a trade-off between ripple and response time
- Specifications
- Input Current: 1500AC current max, sine wave, single phase 50/60/400Hz
- Voltage Rating: 600VAC, tested with 2.5kVDC for 60 seconds
- Output Voltage: 2.5VDC at Full Range. True RMS Conversion for AC sine waves only
- Ratio and Linearity Accuracy
- +/- 1% from 10% to 100%
- +/- 3% at 5% of Full Scale
- +/- 5% at 2% of Full Scale
- Response Time: Approximately 500 milliseconds from 10% to 90% of amplitude for CT’s over 100A
- Output Resistance: 100 to 3,500Ω, depending on current rating
- Interface Resistance: 100kΩ minimum. Other instrument impedances can be interfaced on special order
