CSDA 系列数字式电流传感器， 0.25 A 至 1.0 A 工作电流， 通孔设计， 逻辑电平电流沉输出， 在交流或直流电下工作， 引出线类型 1 PCB 引脚。
CSDA 系列的数字电流传感器均提供逻辑电平输出，当感应电流超出了工作点时，该逻辑电平输出会从近似电源电压变为 0.4 V。每个数字传感器都可以采用交流或直流电流供电，但当传感器传感 AC 电流时，一旦过零，输出都会关闭。

FEATURES DIGITAL/INDUCTIVE CURRENT SENSORS CSDA Series. Features: Open collector output • Digital output • ac or dc currents • Thru-hole design • Output voltage isolation from input • Minimum energy dissipation • Maximum current limited only by conductor size • Enhanced accuracy, lowcost sensing • RoHS compliant Benefits: Single digital (TTL logic level, open collector) output that will sink 20 mA of output current. Provides logic level output that changes from Vcc to 0.4 V when sensed current exceeds the operate point. Will not be damaged by overcurrent in the sensed conductor. Potential applications include variable speed drives, overcurrent protection, ground fault detectors, current feedback control systems, robotics, UPS and telecommunication power supplies, welding power supplies, battery management systems, and wattmeters. continued on back page CLOSED LOOP CURRENT SENSORS CSNB, CSNA, CSNC, CSNE, CSNF, CSNG, CSNJ, CSNK, CSNL, CSNM, CSNP, CSNR, CSNS, CSNT, and CSNX Series. Features: Current sensing up to 1275 A • ac, dc, and impulse currents • In-line or thru-hole design • Competitive cost/ performance ratio • Rapid response • Reduced overshoot • High overload capability • High level of electrical isolation between primary and secondary circuits • Industrial operating temperature range • Small size and weight • RoHS compliant • CE, UL approvals Benefits: Based on the principles of the magnetoresistive or Hall effects, and the null balance or zero magnetic flux method (feedback system). Magnetic flux in the sensor core is constantly controlled at zero. Potential applications include variable speed drives, overcurrent protection, ground fault detectors, current feedback control systems, robotics, UPS and telecommunication power supplies, welding power supplies, battery management systems, and wattmeters. OPEN LOOP CURRENT SENSORS CSCA-A Series. Features: ac, dc, and impulse currents • Competitive cost/performance ratio • Low power consumption • Compact size • High level of electrical isolation between primary and secondary circuits • Large primary aperture • RoHS compliant • CE, UL approvals Benefits: Based on the principles of the Hall-effect wherein a Hall-effect device (HED) produces an output voltage linearly related to the amplitude and phase of a magnetic field applied to it. HED output is directly proportional to the amplitude and phase of the primary current. Potential applications include variable speed drives, overcurrent protection, ground fault detectors, current feedback control systems, robotics, UPS and telecommunication power supplies, welding power supplies, battery management systems, and wattmeters
