EM Test LD 200N Load Dump Generator

60V, 30A

The EM Test LD 200N Load Dump Generator is designed to simulate high-energy load dump pulses that can be caused by sudden battery disconnection during charging. The LD 200N can deliver open-circuit voltages up to 200 V, pulse durations between 40 ms and 400 ms, and rise times from 5 ms to 10 ms. This transient generator is designed with selectable source impedance between 0.5 Ω and 38 Ω in 0.1 Ω increments.

Generates clipped load dump pulses (optional built-in module).
Built-in 0.5 - 38 ohm source impedance, selectable in 0.1 ohm steps.

Load Dump pulses simulate the disconnection of the battery from the alternator while the alternator is generating current to load the battery
The LD 200N simulates these high energy pulses (used in automotive and telecom industries)
