CR Magnetics, Inc. Current Sensors CR4211S-70

The CR4211S-70 is a self-powered AC current transducer designed for DIN rail or panel mounting. It provides a 0-10 VDC output signal that is proportional to the average RMS input AC current, with an input range of 5 to 200 AAC. This device is suitable for multi-point current sensing applications, including monitoring motor faults and heating or lighting elements. Key specifications include a basic accuracy of 0.5%, a response time of 250 ms, and an operating temperature range of 0°C to +60°C. The transducer is constructed to meet various regulatory standards, including UL 61010B-1 and IEC 61010-1. It features a split core design for easy installation and requires no external power source, making it a cost-effective solution for current monitoring needs. The device is also rated for a maximum altitude of 2000 meters and can operate within a frequency range of 50Hz to 400Hz.
