The HAS300-S is a current transducer manufactured by LEM. It's designed for accurate and reliable measurement of AC, DC, and pulsed currents in various industrial and automotive applications. These transducers utilize closed-loop Hall effect technology to provide galvanic isolation between the primary conductor and the measurement circuit.
Applications:
- AC variable speed drives
- Servo motor drives
- Static converters for DC motor drives
- Battery supplied applications
- Uninterruptible Power Supplies (UPS)
- Switched Mode Power Supplies (SMPS)
- Welding applications
Features:
- Closed-loop Hall effect technology
- Galvanic isolation between primary and secondary circuits
- Excellent linearity and accuracy
- Low temperature drift
- Fast response time
- Compact design
- Easy to mount
Benefits:
- Provides precise current measurement
- Enhances system safety through galvanic isolation
- Reduces energy consumption through efficient monitoring
- Improves control system performance
- Simplifies system design
- Increases system reliability
Additional Details:
The HAS300-S typically measures currents up to 300A. It operates on a single power supply, usually +5V or ±12V to ±15V, depending on the specific model. The output is a current proportional to the measured current. Key specifications include accuracy (typically less than 1%), linearity (typically less than 0.1%), and a response time of a few microseconds. The operating temperature range is generally from -40°C to +85°C. These transducers are designed to meet stringent industrial standards for safety and EMC.
