currents
- Wide Operating Temperature Range: -40℃ to +85℃
Operating Conditions:
- Power Supply Voltage: ±12V to ±15V DC (±5%)
- Coil Resistance: 30Ω
Application Fields:
- Variable Frequency Drives: Monitors current in variable frequency
drives to ensure normal operation and protect equipment
- Overcurrent Protection: Real-time current monitoring in circuits to
trigger protection mechanisms when current exceeds set values
- Power Supply Systems: Monitors output current of power supplies to
ensure stable supply and protection
- Feedback Control Systems: Provides accurate current information for
feedback control systems to achieve precise control
- Robotics: Suitable for robot drive systems to monitor motor
current, aiding in precise motion control and fault diagnosis
- Welding Equipment: Monitors current in welding equipment to ensure
welding quality and equipment safety
