Product Overview
The YADA YDG-HSD-3 Hall Effect Current Sensor is a high-precision, isolated current transducer engineered for industrial applications such as UPS systems, inverters, data centers, and power monitoring equipment. It delivers a proportional analog output (e.g. 0-5 V) for input currents up to 100 A (or your specified max). With excellent linearity, fast response, and stable performance in harsh electrical environments, it’s an ideal choice for system integrators and OEMs needing reliable current sensing.

Key Features & Benefits
-
High Accuracy & Linearity — Low non-linearity error ensures precise current measurement.
-
Electrical Isolation — Uses Hall effect principle to isolate the primary current path from the output circuitry, improving safety in high-voltage systems.
-
Wide Measurement Range — Supports 0–100 A AC or DC (or as per your specification).
-
Standard Analog Output — Outputs 0–5 V (or configurable), easy for direct interfacing with ADC, controllers, or monitoring systems.
-
Fast Response Time — Enables real-time detection of current fluctuations in dynamic loads.
-
Low Insertion Loss & Low Offset — Minimal disturbance to main circuit; stable offset ensures accurate zero-current reading.

Applications & Use Cases
-
UPS and Backup Power Systems — Monitor load current and support overcurrent protection.
-
Solar / Hybrid Inverter Systems — Track DC or AC current for optimization and safety.
-
Data Centers & Server Enclosures — Real-time current feedback for power management and energy efficiency.
-
Battery Management Systems (BMS) — Measure charge/discharge currents in energy storage systems.
-
Industrial Automation & Motor Control — Current sensing for motor drives, protection, and fault detection.
-
Switchgear Panels & Energy Monitoring — Integrate into energy management systems for audit and control.
Why Choose YDG-HSD-3 over Traditional Methods
Hall effect current sensing offers several advantages over resistive shunts or current transformers:
-
Non-intrusive & isolated measurement — No physical insertion loss or heat in the main path.
-
Works with both AC and DC — Unlike many traditional current transformers which only support AC.
-
Better temperature stability and lower parasitic effects — In high-speed or high-frequency systems.
-
Compact and easier integration — More flexible in design and layout.
Installation & Wiring Guidelines
-
Fix the sensor securely via mounting holes or panel bracket.
-
Route the conductor whose current you want to measure through the sensor or connect per the input terminal.
-
Ensure correct polarity of power supply to the sensor and orientation of the conductor.
-
Connect the analog output (0–5V) to your monitoring or control system (e.g. ADC input).
-
Add filtering or shielding for EMI suppression if the environment has high interference.
