27. sudden interruption of currents in a device connected in parallel with the DUT due to the inductance of the wiring harness 2 2 Features The FLX 5510 is shipped with two DIY 5510 submodules one populated with an example 3ms circuit and one unpopulated ready to accept your own project Of course you can use modify or reuse the example DIY 5510 for additional projects or keep it as the example Additional DIY 5510 submodules are available separately The FLX 5510 can be fitted into an available slot in the NSG 5510 but we recom mend temorarily replacing the MT 5510 or using the NSG 5500 2 which contains space for additional modules The FLX 5510 module can generate pulses up to 30 ms pulse width td which is exactly where the very flexible load dump generator LD 5550 starts The FLX 5510 and each DIY 5510 submodule can generate pulses over 600 V The DIY 5510 fea tures parallel discharge resistors to the storage capacitors to make sure that the modules return to a safe discharged state very quickly after a DIY 5510 is removed The DIY 5510 also contains a BNC output for use with other external couplers such as a CDN 500 capacitive coupling for use with a LISN etc The DIY 5510 features a special rugged coating that is writeable The surface is also reusable because it is both writeable and erasable if a pencil is used Only one pulse and its corresponding characteristics can be programmed per DIY 5510 sub module but the voltage
