RTC100LAH current sensor

Product catalog summary

Overview: The RTC100LAH Series Closed Loop Mode Hall Effect Current Sensor by Rongtech Industry (Shanghai) Inc. is designed for accurate electronic measurement of DC, AC, or pulsed currents using the Hall effect and null balance method. The sensor outputs a balancing current that mirrors the primary current, which can be converted to voltage through a resistor.

Specifications:

Rated Input (Ipn): 50A for RTC50LAH, 100A for RTC100LAH
Measurement Range (Ip): 150A for RTC50LAH, 280A for RTC100LAH
Rated Output (Isn): 25±0.5% mA for RTC50LAH, 50±0.5% mA for RTC100LAH
Turns Ratio (Np/Ns): 1:2000
Supply Voltage: ±12 to ±15 V
Power Consumption: 20+IpX(Np/Ns) mA
Offset Current: ≤±0.2 mA at Ipn=0
Response Time: <1 µs at 200A/μs, 10%-90%
Linearity: ≤0.1 %FS
Galvanic Isolation: 5.0 KV at 50, AC, 1min
Bandwidth: DC to 200 kHz

Applications: The sensor is suitable for variable speed drives, welding machines, battery-supplied applications, uninterruptible power supplies (UPS), electrochemical processes, and switched mode power supplies (SMPS).

General Data:

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

Mechanical Dimensions: Dimensions are provided for reference with a general tolerance of ±1mm.

Directions for Use: Ensure correct wiring to avoid sensor damage. Custom designs are available for different rated input currents and output voltages.

Standards: The sensor complies with UL94-V0, EN60947-1:2004, SJ 20790-2000, IEC60950-1:2001, and EN50178:1998 standards, with a test voltage of 1000V.

Catalog excerpts

Rongtech © The TBC-LAH current sensor is a closed loop device based on the principle of the hall effect and null balance method. The output from the current sensor is the balancing current which is a perfect image of the primary current reduced by the number of secondary turns at any time. This current can be expressed as a voltage by passing it through a resister. It provides accurate electronic measurement of DC,AC or pulsed currents.
