KP-1240S High Voltage Current Carrying Test System with 1.53 kV Peak Voltage and

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.

• Isolation: >10 kV isolation between output and control circuits
• Discharge Mechanism: Automatic residual energy discharge after each pulse
• Compliance Testing Modes: Pre-programmed sequences for multiple shocks (5-10 pulses as per standard protocols)
• Environmental Specifications: Operating temperature 10-40°C, humidity <80% non-condensing
• Power Supply: 220V AC ±10%, 50/60 Hz, <500W consumption

• Waveform Type: Monophasic truncated exponential waveform (simulating typical external defibrillator output)
• 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.

• Defibrillation shock withstand testing for four-pole connectors in implantable cardiac pacemakers
• Safety evaluation of connector systems in ICDs (Implantable Cardioverter Defibrillators)
• Compliance verification with the international standard ISO 27186:2020
• Support for medical device registration and certification testing

• High-precision waveform control: Digital adjustment of voltage, current, and duration for excellent repeatability
• Safety protection mechanisms: Overload protection, short-circuit protection, and emergency stop function
• Data recording: Built-in waveform acquisition and storage for easy test report generation
• User interface: Touchscreen control with multi-language support (Chinese/English)

In today's increasingly globalized medical device industry, test equipment compliant with the latest ISO 27186:2020 standard has become essential for connector testing in implantable cardiac devices. The KP-1240S not only retains compatibility with YY/T 0972-2016 but has been fully upgraded to the 2020 international standard, helping companies efficiently meet CE marking, FDA approval, and other global registration requirements.

If you are conducting defibrillation withstand testing for implantable pacemaker or ICD connectors, the KP-1240S is your reliable choice, ensuring product safety and market competitiveness.
