 ISO 7637-TP2b,4 simulator is designed for automotive electronics equipment immunity test

Pulse 2b simulates transients from d.c. motors acting as generators after the ignition is switched off. This pulse 4 simulates supply voltage reduction caused by energizing the starter-motor circuits of internal combustion engines, excluding spikes associated with starting. Full compliant with the latest standards of ISO7637-2,-3 

 Full compliant with the latest standards: ISO7637-2

LCD display, Intelligent control, reliable performance

System can be efficient and flexible combined, can be alone operated, also can be Unified control  through the microcomputercontrol operation.

Use the Programmable imported high-voltage power supply, Reliable performance

Built-in international standards level parameters and user model parameters,

Positive and negative polarity are automatically switched, easy to operate.

 Built –in the adjustable dc power in system

Built-in the RS232 interface ,Remote operated by the optional control software.
