WATT TRANSDUCER

The SWARTZ® Watt Transducer is a high performance, solid-state unit specifically developed to meet requirements for supervisory control and data acquisition (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

The Watt Transducer is constructed on a fl angled base and may be mounted in any orientation. Electrical connection via screw terminal barrier strips. “Gain” and “Zero” adjustment trimpots are located on the top cover for calibration or for setting intentional offsets. Voltage and current are multiplied in the high voltage section for highest accuracy and the watts output is fed to a full wave FET chopper that provides high voltage isolation between feeder circuits and current loop output. The output is a bipolar current source and tracks the input signal with current feedback located in the positive output for the best performance.

CURRENT TRANSDUCER

The SWARTZ® Current Transducer is a high performance, solid-state unit specifically developed to meet requirements for supervisory control and data acquisition (SCA- DA) systems. The transducer is ruggedly constructed for the transit substation environment and operates from DC “housekeeping” battery supplies without use of separate AC inverters.

The Current Transducer is constructed on a fl anged base and may be mounted in any orientation. Electrical connection 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 + 100mV; full range. The output is a bi-polar current source that tracks the input signal with current feedback located in the positive output for the best performance.
