KP-1240S High Voltage Current Carrying Test System | ISO 27186:2020 Quadripolar Connector Defibrillation

KP-1240S High Voltage Current Carrying Test System with 1.53 kV Peak Voltage and ≥50 A Current Peak for ISO 27186:2020 Compliant Defibrillation Pulse Testing

The High Voltage Current Carrying Test System is a professional high-current pulse test instrument designed to generate monophasic truncated exponential defibrillation pulses for evaluating the high-voltage and high-current withstand capability of quadripolar (IS-4/DF-4) connector systems in active implantable cardiac rhythm management devices, in full accordance with ISO 27186:2020 Annex E.

Technical Parameters

Waveform Performance Parameters

The High Voltage Current Carrying Test System features a robust high-voltage and high-current pulse generation circuit with advanced isolation (>10 kV) between output and control circuits. It incorporates programmable energy control, real-time waveform monitoring, and precise digital adjustment of voltage, current and duration for excellent repeatability.

Safety-critical systems include automatic residual energy discharge after each pulse, overload/short-circuit protection, and emergency stop function. The compact desktop design with touchscreen control and built-in data recording facilitates easy integration into R&D and certification laboratories while ensuring full compliance with ISO 27186:2020 Annex E.

Testing Principle

The High Voltage Current Carrying Test System applies a monophasic truncated exponential high-voltage, high-current pulse (peak voltage 1.53 kV, peak current ≥50 A, 18 ms duration) directly across the quadripolar connector of the implantable device under test. After the pulse, the device is evaluated for permanent damage and functional integrity through immediate reprogramming verification, confirming the connector’s ability to withstand defibrillation shocks as required by ISO 27186:2020 Annex E.

Common Error Mitigation

To ensure maximum repeatability, always verify actual output waveform parameters (peak voltage, peak current, rise time and decay) using a calibrated high-voltage oscilloscope and current probe before each test sequence. Confirm secure connection of the quadripolar test fixture and correct load impedance (50–100 Ω). Perform immediate post-pulse reprogramming verification to accurately assess device recovery. Annual calibration of the high-voltage and high-current circuits is recommended to maintain traceability.
