PCI-Short Pulse Generator 5kA (350 kV) – EMP300K-5-500
High-Voltage Pulse Generator for MIL-STD-188-125-1/2 Testing
The EMP300K-5-500 is a PCI-Short Pulse Generator designed to evaluate the performance of conductive points of entry (POE) and protective devices according to MIL-STD-188-125-1/2 standards. This high-precision Marx generator delivers double-exponential current pulses with peak levels up to 5 kA, ensuring accurate and repeatable testing for electromagnetic pulse (EMP) protection.
Engineered for military, aerospace, and high-voltage research applications, the EMP300K-5-500 is fully computer-controlled via RS232 and USB interfaces and integrates seamlessly with automation software.
Typical Test Setup
The EMP300K-5-500 delivers a high-current pulse either directly or through coupling devices to test the effectiveness of protective devices at electrical entry points. A residual pulse enters the protected facility, which is monitored using current probes connected via fiber optics to an oscilloscope inside a shielded enclosure.
