Measurement Range (Ip): 160A for RTC50LAS5, 300A for RTC100LAS5
Rated Output: 0.625V ±0.5%
Turns Ratio: 1:1200
Supply Voltage: +5V ±5%
Response Time: <0.5 µs
Bandwidth: DC to 100 kHz

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

General Data:

Operating Temperature: -40 to +85 ºC
Storage Temperature: -40 to +125 ºC
Mass: Approximately 22g

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

Mechanical Dimensions: Dimensions are provided in millimeters 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.

Characteristics: The sensor effectively follows di/dt changes greater than 100 A/µs and provides galvanic isolation of 5.0 KV for 1 minute at 50 AC.

Catalog excerpts

The RTC100LAS5 series 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. 1.Variable speed drives 2.Welding machine 3.Battery supplied applications 4.Uninterruptible Power Supplies (UPS) 5.Electrochemical Switched Mode Power Supplies (SMPS)
