RTC300TAH close loop current senesor

Product catalog summary

Overview: The RTC300TAH Series is a high precision closed loop Hall Effect current sensor designed by Rongtech Industry (Shanghai) Inc. It utilizes the Hall effect and null balance method for accurate DC, AC, and pulse current measurements, offering galvanic isolation between primary and secondary circuits.

Specifications:

Rated Current (Ipn): Ranges from 5A to 300A depending on the model.
Measurement Range (Ip): Up to 900A with varying resistance values.
Turns Ratio: Varies from 1:1000 to 1:3000.
Supply Voltage: ±12V to ±18V.
Response Time: Less than 1.0 μs at 100A/μs.
Bandwidth: DC to 100 KHz.
Operating Temperature: -40°C to +85°C.
Storage Temperature: -40°C to +125°C.

Applications: Suitable for variable speed drives, welding machines, battery applications, UPS, and electrochemical processes.

Standards: Complies with UL94-V0, EN60947-1:2004, IEC60950-1:2001, EN50178:1998, and SJ 20790-2000.

Directions for Use:

Ensure the primary conductor does not exceed 120°C.
Optimal performance when the primary hole is fully filled with the bus bar.
Primary turns should be at the top for best magnetic coupling.
Correct wiring is crucial to avoid sensor damage.

Connection Details: The sensor uses a Molex connector with specific wire color coding for power and output signals.

Catalog excerpts

The RTC300TAH Series current sensor is a closed loop device based on the measuring principle of the hall effect and null balance method ,with a galvanic isolation between primary and secondary circuit, the size of primary doesn't affect test precision, no matter the location of primary in the hole of current sensor, It can really measure resolution 1000:1 and it uses for precision measurement of DC, AC and pulse current.
