RTC200ECH Series

Product catalog summary

Overview: The RTC200ECH Series current sensor by Rongtech Industry (Shanghai) Inc. is a closed-loop device utilizing the Hall effect and null balance method. It provides galvanic isolation between primary and secondary circuits and maintains precision regardless of the primary's position within the sensor. It is designed for precise measurement of DC, AC, and pulse currents with a resolution of 1000:1.

Electrical Specifications:

Rated Input (Ipn): Ranges from 5-200 A depending on the model (RTC50ECH to RTC200ECH).
Measurement Range (Ip): Up to 500 A with varying resistance values based on voltage and current.
Turns Ratio: Varies from 1:1000 to 1:2000.
Coil Resistance: Ranges from 30 to 55 Ω.
Supply Voltage: ±12 to ±18 V.
Power Consumption: ≤20+Ip/Ns mA.
Offset Current: ≤±0.15 mA at Ip=0.
Linearity: ≤0.1 %FS.
Bandwidth: 0 to 200 KHz.
Response Time: Less than 1.0 μs.
Galvanic Isolation: 3 KV at 50Hz, AC, 1 minute.

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

Mechanical Dimensions: Dimensions are provided in mm with a general tolerance of ±1.0mm.

Usage Directions:

Current direction follows the arrowhead for forward direction.
Primary conductor temperature should not exceed 120℃.
Optimal dynamic performance when the primary hole is fully filled with the bus bar.
Primary turns should be at the top for best magnetic coupling.
Voltage is measured at the output end when current passes through the sensor.
Custom designs are available for different rated input and output currents.

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

General Data:

Operating Temperature: -40 to +85 ºC.
Storage Temperature: -40 to +125 ºC.
Mass: Approximately 15 g.

Characteristics Chart: Includes pulse current signal response characteristics and effects of impulse noise.
