Test for IEC EN 61643-321 Avalanche Prevention Diode

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 61643-321 testing. Standard made for the control of avalanche fault diodes, representing a type of surge protection device component (SPDC) used in the design and construction of surge protective devices connected to low-voltage power distribution systems, transmission and signaling networks.

The standard specifies test circuits and procedures used to evaluate US performance. These tests simulate surge conditions that the US is likely to encounter in real use, such as lightning surges, switching surges, and power frequency overvoltages.

The tests are designed to determine the electrical characteristics of the US, including breakdown voltage, clamping voltage, and response time.

The standard defines test parameters for the US, such as the peak current and voltage, the rise and duration of the surge, and the test waveform. It also specifies test conditions such as temperature and humidity that must be maintained during testing.

IEC 61643-321 is intended for use by manufacturers, designers, and installers of the USA and end users who need to select and install surge protection devices in their power systems.

The standard helps ensure that the US meets required performance standards and can effectively protect equipment and installations against transient overvoltages.
