Electrical safety tester HFCN

signalfor electrosurgical unitsfor electrocardiograph

Overview
The HFCN test fixture is a high-frequency coupling network designed for electrosurgery interference (ESIO/ESIS) testing and compliance verification with IEC 60601 series, China YY1079 and AAMI EC13. It integrates dual test modules and a breakout box to reproduce skin impedance and provide an ECG simulation path for standardized interference measurements.

Highlights

• Dual-module configuration (Module A and Module B) for separate ESIO/ESIS and ECG simulation functions
• Built-in skin-impedance circuit: 51 kΩ / 47 nF (C0G) to simulate patient path
• ECG simulator in Module B producing 1 mV ±10% signals for ESIS testing
• High power handling: overall test fixture rating >300 W; non-inductive power resistors specified 200 W/pcs
• Low resistor inductance (<5 μH) and wide frequency range DC to 100 MHz
• Compatible with BB-C1 breakout box and WhaleTeq SECG 4.0 / MECG 2.0 software tools
