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
Technical Specification (Compliant with ISO 27186:2020 Annex E)
The KP-1240S High Voltage Current Carrying Test System is a specialized test instrument designed to generate high-intensity pulse currents simulating defibrillation shocks for active implantable medical devices. This system is designed and manufactured in accordance with the requirements of Annex E (normative) in ISO 27186:2020 — Active implantable medical devices — Four-pole connector system for implantable cardiac rhythm management devices — Dimensions and test requirements, serving as an updated supplement to the original Annex E in YY/T 0972-2016.
The primary purpose of this test system is to evaluate the four-pole connector system (IS-4/DF-4) in implantable cardiac rhythm management devices (such as pacemakers and ICDs) for permanent damage when subjected to external high-voltage defibrillation pulse currents, and to verify whether the original settings can be restored through reprogramming, thereby assessing the safety and reprogrammability of the connector.

| Pulse Duration | 10 - 20 ms (adjustable; default 18 ms truncated exponential decay) |
| Waveform Rise Time | < 10 µs (fast rise to simulate real defibrillator shocks) |
| Energy Delivery | Up to approximately 200 J (calculated based on waveform and load) |
| Repetition Rate | 1 - 10 pulses per minute (manual or automated sequencing) |
| Load Simulation | Built-in resistive load (50 - 100 Ω) to mimic patient impedance during external defibrillation |
| Polarity Switching | Automatic or manual selection of positive/negative polarity |
| Measurement Accuracy | Voltage ±1%, Current ±2%, Time ±0.5% |
| Output Connections | High-voltage safety connectors compatible with IS-4/DF-4 test fixtures |

- Polarity: Positive or negative polarity selectable (meeting the standard requirements for monophasic waveforms)
- Maximum Peak Voltage: 1.53 kV (exceeding 1500 V, satisfying high-voltage shock requirements)
- Peak Current in Test Circuit: ≥50 A (measured under standard load, ensuring sufficient shock intensity)
- Pulse Duration: 18 ms (precisely controlled truncation time, compliant with exponential decay waveform characteristics)
This system is designed with ISO 27186:2020 Annex E as the core reference, which specifies the high-voltage pulse withstand test method for four-pole connector systems, including simulation of high-energy pulses applied to the connector by an external defibrillator.
Compared to YY/T 0972-2016, ISO 27186:2020 updates the dimensions, electrical, and functional requirements for four-pole connectors (IS-4 low-voltage type and DF-4 high-voltage type) and strengthens functional compatibility testing under high-voltage shocks.
The test pulse is designed to ensure no permanent damage to the connector after high-voltage impact and to support reprogramming recovery of the pulse generator, verifying overall system safety and reliability.
