CSCA-A Series Hall-Effect Based Open-Loop Current Sensors DESCRIPTION The CSCA-A Series of open-loop current sensors are based concentrated in the gap in this core. The HED is located in this on the principles of the Hall-effect wherein a Hall-effect device core gap. Therefore, the HED output is directly proportional to (HED) produces an output voltage linearly related to the the amplitude and phase of the primary current. amplitude and phase of a magnetic field applied to it. The HED output is trimmed for gain and offset calibration such Current flowing through a primary conductor generates a that the CSCA-A Series sensor provides a predefined output rotating magnetic field around the conductor. This field is sensitivity versus primary current. collector by a core of magnetically sensitive material and FEATURES POTENTIAL APPLICATIONS Measures ac, dc and impulse currents Variable speed drives Competitive cost/performance ratio Ground fault detectors Low power consumption Current feedback control systems Compact size Robotics High level of electrical isolation between primary and UPS and telecommunication power supplies secondary circuits Welding power supplies Large primary aperture Automotive - Battery management systems RoHs compliant Watt meters CE, UL approvals (pending) CSCA-A Series SPECIFICATIONS (all specifications are at 15 Vdc supply and 25 C 77 F ambient temperature unless otherwise specificed) Characteristic Symbol Parameter Nominal current I See product selection guide PN Peak measuring range (ac peak) I See product selection guide PK Nominal output voltage at I V 4 V 1 % PN SN Supply voltage V 15 Vdc 5 % cc Supply current I 17 mA typ. cc 1 Accuracy at I X < 2 % of I PN PN 2 Linearity E < 1 % I Zero current offset V < 20 mV O V < 20 mV Residual offset after I OR PN Thermal drift of offset V < 3 mV/C I = 50 A OT PN < 1.5 mV/C I = 100 A to 600 A PN Thermal drift of gain V < 4 mV/C ST 3 Response time t 3 s to 7 s R di/dt accuracy followed di/dt > 50A/s Bandwidth f dc to 50 kHz Isolation voltage V 3 kV, 50 Hz, 60 sec D Rated insulation voltage V 849 V reinforced I Output resistance R > 10 kOhm S Ambient operating temperature T -10 C to 80 C 14 F to 176 F A Ambient storage temperature T -25 C to 85 C -13 F to 185 F S NOTES: 1 For I > I then X is the same percentage value but of I P PN P 2 Independent linearity per the Instrument Society of America 3 At 90% of I P 4 Appropriate specification items defined using the guidance of EN50178 2 www.honeywell.com/sensing
