Hall Current Transformer for Accurate Wide-Band AC/DC Current Monitoring

The Hall Current Transformer from Jiangyin yucheng Electric Co., Ltd. is developed based on Hall effect principle for multi-waveform current precise measurement and signal acquisition in new energy, industrial control and intelligent power systems. Different from traditional electromagnetic CTs, this series integrates high-performance Hall sensing chips and split core piercing structure, realizing complete electrical isolation between primary and secondary circuits to deliver safe, stable and full-spectrum current monitoring for industrial, new energy and smart electrical scenarios.

Electrical Performance and Technical Specifications

To meet complex measurement, control and protection demands, the Hall Current Transformer comes with comprehensive technical parameters:

• Rated input: 1A ~ 1000A (AC/DC/pulse current compatible)
• Rated output: 0–5V, 0–10V or 4–20mA standard signal
• Accuracy: Linear error ≤ ±0.2%, Zero drift ≤ ±0.1%FS
• Measuring range: 0%In ~ 150%In, support transient peak current capture
• Working frequency: 0–20kHz, covering DC, low frequency and medium frequency power signals
• Core materials: High permeability permalloy magnetic ring + high-stability Hall sensing chip
• Shell material: Flame retardant ABS, UL94-V0 fire resistance grade
• Internal structure: Environmental friendly epoxy resin fully sealed casting
• Connection: Terminal outlet with 1.5m shielded cable, anti-interference wiring

These parameters guarantee ultra-wide linear range, fast response speed and powerful anti-electromagnetic interference capability, supporting lossless signal transmission to PLC, data acquisition instruments and protection controllers.

Key Applications

The Hall Current Transformer is perfectly applicable to multiple industries and equipment:

• New energy systems: Photovoltaic inverters, energy storage converters, wind power control cabinets
• DC power supply equipment: UPS, DC screen, charging pile, industrial DC power supply
• Motor drive & automation: Frequency converter, servo drive, industrial motor real-time current feedback
• Electrical safety monitoring: DC leakage detection, battery pack monitoring, electrical fire early warning
• Power quality analysis, small current grounding protection and laboratory precision testing

It is especially suitable for projects requiring AC/DC mixed measurement, electrical isolation and high-speed signal feedback for intelligent control systems.

Structural and Installation Advantages

Split Piercing Core Design

The split openable magnetic core structure enables on-site installation without cutting off main cables or power shutdown, greatly reducing construction downtime and production interruption.

High Isolation & Long-Term Stability

Epoxy full sealing and primary-secondary reinforced insulation design (withstand voltage 3kV AC/min) effectively isolate high voltage interference; permalloy magnetic ring minimizes magnetic hysteresis error to maintain long-term consistent measurement precision.

Ultra-Wide Compatible Measurement Range

Covers 1A to 1000A AC/DC current, one single transformer matches small control loops, medium power circuits and heavy-current main busbars, reducing model inventory.

Compact and Reliable Panel Mounting

Integrated ABS flame retardant shell and reinforced plastic skeleton possess excellent mechanical shock resistance; reserved screw fixing holes for firm installation inside low-voltage cabinets and equipment enclosures.

Installation & Maintenance

• Open the split magnetic core buckle, thread the cable or copper busbar through the transformer inner window
• Fasten the transformer to cabinet mounting rail with fixing screws
• Connect secondary shielded wire output (0–5V/0–10V/4–20mA) to control or acquisition devices

Routine maintenance workload is minimal; only periodic inspection of wiring tightness and shell integrity is required.
