The Schr ö der lightning surge generator is characterized by high-precision simulation, intelligent operation, multi standard compatibility, and safety and reliability, and is widely used in electromagnetic compatibility testing (EMC) of electronic and electrical equipment. The following is a detailed interpretation of its product features:

1、 Core functions and technological advantages of Schr ö der lightning surge generator:

1. High precision waveform simulation

Standard waveform generation: Strictly following international standards such as IEC 61000-4-5, it can generate 1.2/50 μ s voltage waveforms, 8/20 μ s current waveforms, and combined waveforms, accurately simulating transient interference caused by lightning strikes or sudden changes in power loads.

Multi level testing support: Built in standard testing levels 1-4 (corresponding to gradually increasing voltage intensity), and supports custom testing sequence storage to meet the rigorous testing requirements of different scenarios.

2. Intelligent operation interface

CWG 1500: adopts a button based operation panel, with clear and intuitive parameter settings, supporting 32 sets of preset parameters for quick calling, suitable for traditional testing scenarios.

CWG 2500: Upgraded to a capacitive color touch screen with no nested menu design. Parameter adjustments can be made in seconds through a rotary encoder, resulting in a 50% increase in operational efficiency.

3. Multi interface compatibility

Communication interface: Provides RS232, USB, and optional fiber optic interfaces, supports PC remote control and data export, and is compatible with laboratory automation testing processes.

Measurement output: Equipped with a BNC connector on the back, it can output surge voltage/current waveforms in real time to the oscilloscope for easy data recording and analysis.

2、 Hardware Design and Safety Performance of Schr ö der Lightning Surge Generator:

1. Wide voltage/current range

Voltage output: continuously adjustable from 200V to 4.4kV, covering the testing needs of low voltage equipment (such as consumer electronics) to high voltage systems (such as industrial power equipment).

Current output: 100A to 2.2kA, supporting alternating positive/negative polarity output, simulating the bidirectional impact characteristics of real lightning strikes.

2. Security protection mechanism

Trigger mode: Supports manual triggering and external triggering, with a synchronized phase accuracy of 1 ° resolution to ensure test controllability.

High voltage protection: The internal resistance of the generator is fixed at 2 Ω to avoid the risk of short circuit; High voltage output supports floating or grounding modes, suitable for different testing environments.

Environmental adaptability: Operating temperature range of 0-40 ℃, weight of about 18kg, suitable for laboratory fixed installation or mobile testing scenarios.

3. Built in coupling network

Differential/Common Mode Measurement: Integrated with L-N, L-PE, and N-PE independent measurement circuits, it can simultaneously monitor line to line (differential mode) and line to ground (common mode) surges, and evaluate the comprehensive anti-interference ability of the equipment.
