Product Performance

369B1859G0022 adopts a 16-bit high-precision A/D converter with a current sampling rate of 10kHz, ensuring fault response time ≤10ms, which can quickly cut off the fault circuit to avoid motor damage. It supports 10 sets of custom protection logic, and realizes flexible configuration of protection parameters through buttons or software configuration, adapting to different motor types and operating conditions.

Integrated with motor health monitoring function, it real-time calculates insulation resistance, bearing temperature trend and load rate, generates operation reports and fault recording (up to 100 event records), supporting data traceability before and after faults. Communication interfaces support dual-network redundancy with data transmission delay ≤50ms, enabling seamless connection with GE PACSystems or third-party SCADA systems.

Wide temperature design and IP54 protection class ensure stable operation in harsh industrial environments, with mean time between failures (MTBF) ≥200,000 hours, supporting online calibration and firmware upgrade without power-off during maintenance.
