ACS712T 30A Range Current Sensor

Linear Hall-Effect Transducer Core: Powered by the Allegro ACS712TELC-30A Hall-effect IC, delivering precise analog voltage output proportional to AC or DC current streams.

Galvanic Voltage Isolation: Features 2.1 kVRMS voltage isolation between the primary copper conductor path and sensitive low-voltage control circuitry for high system safety.

Bi-Directional $\pm 30A Current Sensing Range: Optimized to measure continuous bi-directional currents up to ± 30A, centered around a V_CC/2 zero-current output offset voltage (2.5V).

Factory-Calibrated Sensitivity: Calibrated to an optimized 66 mV/A analog output scale with low thermal drift for straightforward voltage-to-current MCU calculations.

Heavy-Duty Screw Terminal Block: Outfitted with a high-current 2-pin screw terminal block for secure, low-resistance connection to high-load AC/DC lines.

Housing & Board Material: High-grade FR-4 glass-epoxy PCB with surface-mount ACS712 IC, green terminal block, and tinned header pins.

Technical Specifications:

Operating Supply Voltage (V_CC): 5.0V DC.

Current Measurement Range: ± 30A AC or DC.

Sensitivity Rating: 66 mV/A.

Color: Blue PCB with Green Terminal Block and Silver Pins.

Usage Advice: Connect 5V VCC, GND, and OUT to your microcontroller ADC; wire the load line through the screw terminal block pads (IP+ / IP-).

Maintenance: Keep terminal block screws properly tightened; handle with ESD protection and keep PCB surfaces free from dust, moisture, and flux residue.

Essential High-Capacity Current Diagnostic Board: Position as a core Hall-effect current module for heavy-duty DC motor drives, solar array charge monitoring, high-power switching supplies, and over-current trip circuits.

Highlight High Ampere Capacity (30A): Emphasize how 30A rating provides higher load tolerance and thermal headroom than 5A or 20A variants for high-drain power systems.

Recommended Cross-Sell Add-ons: Pair with ACS712T 5A Range Current Sensor, ACS712T 20A Range Current Sensor, Hall Current Sensor ACS758LCB-050B, and ESD antistatic mat 50x40CM PCB Welding Mat.
