-
Applied to onboard airbag timing squib;
- 12 channels or 8 channels;
- Timing step 0.1ms;
- Squib current>2A；
- Airbag resistance monitoring;
- Squib current and voltage data storage.
The onboard airbag timer is mainly used in the vehicle crash test, or in the simulation car test. AT-12C and AT-8C adopt 12-channel and 8-channel design respectively; each channel can be set independently, and the status of the connected airbag can be displayed in real time through its own indicator light. The equipment has a built-in UPS battery and independent burst capacitors for each channel, and it can collect data on burst current and voltage at the same time. The JBUS bus connector can support daisy chain connecting with other JBUS devices.
