HWCT004 Micro Precision Current Transformer 50A / 50MA

High-Precision 1000:1 Current Ratio: Precisely converts 0 - 50A AC primary current to a proportional 0 - 50mA secondary current output (1000:1 turn ratio) for microcontroller sampling.

Compact Ring Core Design: Features a micro ring aperture designed with flying wire leads for easy wiring inside compact junction boxes and power panels.

Galvanic Line Isolation: Fully isolates high-voltage AC mains lines from delicate low-voltage sampling circuits, protecting downstream microcontroller ADCs and host processors.

Fully Encapsulated Epoxy Body: Housed in a flame-retardant blue plastic shell filled with high-dielectric epoxy resin, ensuring resistance against moisture, dust, and mechanical vibration.

High Linearity & Low Phase Shift: Delivers consistent measurement accuracy (≤ 0.2% non-linearity) across standard 50Hz / 60Hz power grid frequencies.

Housing & Board Material: Flame-retardant ABS blue plastic casing filled with high-dielectric epoxy resin and insulated multi-strand copper wire leads.

Technical Specifications:

Primary Rated Input Current: 0A - 50A AC.

Secondary Rated Output Current: 0mA - 50mA AC (1000:1).

Non-linearity: ≤ 0.2%.

Color: Blue Plastic Case with Red and Black Wire Leads.

Usage Advice: Pass the live primary AC wire through the center aperture hole; connect the secondary red/black wire leads across an appropriate burden resistor ($R_B$) to generate a proportional AC voltage for microcontroller ADC sampling.

Maintenance: Ensure wire connections remain securely soldered or connected; keep the transformer body dry, clean, and free from metallic dust and physical stress.

Essential High-Capacity AC Sampling Transducer: Position as a compact, heavy-duty current transformer for sub-metering boards, home energy management systems, solar inverter tracking, and appliance power loggers.

Highlight Compact Wire Lead Integration & High Accuracy: Emphasize how flying wire leads and a small ring footprint allow flexible installation in tight spaces while maintaining precision current conversion (0.2% non-linearity).

Recommended Cross-Sell Add-ons: Pair with HWCT5A/5mA Micro Current Transformer, 20A/10mA Micro Current Transformer, SCT-013-000 Non-Invasive AC Current Clamp Sensor 100A 1V, and ESD antistatic mat 50x40CM PCB Welding Mat.
