Technical Specifications Model: LC1000‑SSP7 Measuring Primary Current: ±1000 A AC / DC Conversion Ratio: 1:4000 Power Supply: ±24 VDC Output Signal: Proportional analog voltage signal Frequency Response: DC to 20 kHz Response Time: Less than 1 μs Isolation Voltage: 2500 Vrms between primary and secondary side Operating Temperature: ‑40 ℃ to +85 ℃ Storage Temperature: ‑45 ℃ to +90 ℃ Relative Humidity: 5‑95 %, non‑condensing Protection Class: IP20 Certifications: CE
Functional Features Hall‑effect non‑contact measurement for AC and DC large current. High‑speed response captures fast‑changing transient current signal. Galvanic isolation between primary high‑current circuit and secondary measuring circuit. High measuring accuracy for wide measuring range. Proportional analog output directly connects to industrial controller analog‑input channel. Compact hollow‑core structure allows primary bus‑bar pass‑through installation. Built‑in over‑range signal limitation protection for secondary output circuit.
Application Scenarios Current‑measurement spare‑part replacement for power conversion equipment such as inverter and rectifier. Real‑time current monitoring for power‑distribution cabinet and large‑capacity motor drive unit. DC‑bus current sampling for new‑energy power‑generation converter equipment. Industrial power‑equipment overhaul and sensor renewal project.
Installation Requirements Fix LC1000‑SSP7 transducer firmly onto cabinet bracket through reserved mounting holes. Pass primary high‑current bus‑bar vertically through central hollow aperture; avoid eccentric offset of bus‑bar inside aperture. Complete ±24 VDC power‑supply wiring and analog‑signal output wiring at secondary‑side terminal block. Secondary‑side signal cable adopts shielded twisted‑pair, separate routing from primary high‑power cable. Implement protective earthing for transducer shell complying with power‑cabinet grounding specification. Verify output signal zero‑point offset after power‑on, complete measuring‑range calibration according to project requirement.
