The rackmount power and trigger system for EMP simulators is designed to provide complete and simple control to the test operator. This system features a local analog control interface and a remote computer control interface over fiber optic. This permits operator control over pulse polarity, charge voltage, and trigger pulse timing for an EMP pulser. The power and trigger module typically works in conjunction with a pressure control system which supports the EMP pulser. The control system can be configured for any mains voltage worldwide. Customizations for various voltage ranges and gas pressure ranges are available.
