|
The SWARTZ® Current Transducer is a high performance, solid-state unit
specifically developed to meet requirements for supervisory control and data acquistion
(SCADA) systems. The transducer is ruggedly constructed for the transit substation
environment and operates from DC "housekeeping" battery supplies without use of
separate AC inverters.
|
 | "Power on" LED |
| Overrange capability |
| Smooth saturation characteristics at range limits |
| High bandwidth to 1 khz |
| Bi-Directional |
|
| Internal Power Supply operates on and auto-compensates for a wide range of DC inputs |
| Magnetic link design; no aging deficiencies or temperature drift |
| Three-way isolation: power supply, input circuit, and output circuit |
|
The Current Transducer is constructed on a flanged base and may be mounted in any
orientation. Electrical connection is via screw terminal barrier strips. "Gain"
and "Zero" adjustment trimpots are located on the top cover for calibration or
for setting intentional offsets. The input is +100 mV; full range. The output is a
bi-polar current source that tracks the input signal with current feedback located in the
positive output for best performance.
