This manual describes the function and use of the DC1950A Load Dump Generator.
The DC1950A is a demonstration circuit designed to generate a load dump pulse for testing 12V and 24V automotive circuits. The output waveform conforms to ISO 7637-2 test pulse 5a, featuring a 2Ω output impedance and automatic adjustment of pulse width as a function of load current. It supports up to 3A for 12V systems and 1.5A for 24V systems.
| Output Impedance | 2Ω |
|---|---|
| Pulse Standard | ISO 7637-2 test pulse 5a |
| Max Load Current (12V) | 3A |
| Max Load Current (24V) | 1.5A |
| Battery Life | 180,000 pulses |
| Cool Down Time | 8 seconds |
| Rise Time (Unloaded) | 10 ms |
| Pulse Duration (Unloaded) | 400 ms |
No, the device has no on/off switch because it draws no current from its batteries in its idling state.
The maximum load current available for testing 24V systems is 1.5A.
The output waveform conforms to ISO 7637-2 test pulse 5a.
