1. Product Overview
The YHDC SCT010T-D is a split core current transformer designed for accurate current measurement in AC circuits. Its split-core design allows for easy installation without disturbing or disconnecting the main cables being monitored. It provides galvanic separation between the primary AC current circuit and the secondary 0-5V DC output circuit.
This device is suitable for monitoring currents ranging from 5A to 50A, providing a 5V output with 1% accuracy. It features a safety lock buckle for secure and easy installation and a screw terminal for output connections.
2. Setup and Installation
The SCT010T-D current transformer is designed for free-hanging (in-line) mounting and features a safety lock buckle for straightforward installation.
2.1 Opening the Split Core
To install the current transformer, gently open the split core by releasing the safety lock buckle. The core can open up to 180 degrees to accommodate the primary conductor.
2.2 Wiring Instructions
The device features a built-in rectifier and screw terminal output for connection. Refer to the schematic diagram for proper wiring.
Schematic Diagram Details (refer to Figure 3):
- The primary current (IF) passes through the core.
- The secondary output is connected to terminals labeled '-L' and '+K'.
- This is a voltage output type current transformer.
- Important Safety Note: The secondary circuit is NOT allowed to be short-circuited.
Connect the output terminals to your monitoring or measurement device. Ensure all connections are secure.
3. Operating Instructions
Once installed and wired correctly, the SCT010T-D will output a DC voltage proportional to the AC current flowing through the primary conductor. This output can be used for various applications:
- Remote control of current measurement: Integrate with distributed PLCs for processes in SCADA systems.
- Load trend monitoring: Monitor critical motors (e.g., compressors, fuel pumps) and other loads up to 150A.
- Energy monitoring: Conveniently connect to power consumption submeters.
The output voltage will correspond to the measured current based on the selected input range (5A, 10A, 20A, 30A, or 50A) and the specified 5V output. For example, if you have a 50A input model with a 5V output, a 50A primary current will result in a 5V DC output.
4. Maintenance
The YHDC SCT010T-D is designed for reliable, long-term operation with minimal maintenance. Follow these general guidelines:
- Keep Clean: Ensure the device is free from dust, dirt, and moisture. Use a soft, dry cloth for cleaning.
- Inspect Connections: Periodically check the screw terminal connections to ensure they remain tight and free from corrosion.
- Environmental Conditions: Operate and store the device within the specified temperature and humidity ranges to ensure optimal performance and longevity.
- Avoid Physical Damage: Protect the device from impacts or excessive force that could damage the core or housing.
5. Troubleshooting
If you encounter issues with your SCT010T-D current transformer, consider the following troubleshooting steps:
- No Output/Incorrect Reading:
- Verify that the primary conductor is correctly routed through the split core and the core is securely closed with the safety buckle.
- Check all wiring connections at the screw terminals for proper polarity and secure contact.
- Ensure the connected monitoring device is functioning correctly and configured for the expected voltage input range.
- Confirm the primary current is within the rated input range of your specific SCT010T-D model.
- Intermittent Readings:
- Check for loose connections at both the CT and the monitoring device.
- Ensure there is no electromagnetic interference from nearby high-power equipment.
- Physical Damage: If the housing or core appears damaged, discontinue use and replace the unit.
If the problem persists after performing these checks, contact technical support for further assistance.
