Introducing the SAME SKY CS2050BL current sensor, a high-precision, open-loop bipolar current transducer designed for accurate current measurement applications. Manufactured in Japan, this sensor is RoHS compliant and ideal for integration into various electronic systems requiring reliable current sensing.
Key features include:
Open loop measurement principle for straightforward installation
Bipolar operation supporting both positive and negative currents
Low noise output for enhanced signal integrity
Single channel configuration for simplified design
The CS2050BL supports a rated current (If) of ±20A with a linearity range of ±30A peak. It operates at a supply voltage of ±4.75V to ±5.25V, consuming a maximum of 25mA current. The output voltage at the rated current is approximately 2.00V, with minimal offset voltage after demagnetization.
Specifications include:
Output voltage linearity: ±0.5%
Response time: 7 μs
Operating temperature: -10°C to 75°C
Storage temperature: -30°C to 90°C
Insulation resistance: 500 MΩ at 500Vdc
Withstand voltage: 2,000 Vac for 1 minute
Hysteresis: 8 mV at +If to zero current
Max primary overcurrent (no damage): 10×If
The sensor's mechanical dimensions are 15 x 15 x 20 mm, with phosphor bronze terminals plated with tin for durability. It is packaged in a tray for easy handling and installation.
