EMC-7637

With the vehicle's operation and safety become increasingly dependent on the complexity of inligent vehicle control systems, along with the popularity of automotive inligent technology, more and more electronic products have been used by automotive manufacturers, such as automotive electronic braking systems, electronic control of transmission, electronically controlled steering systems, automotive communications systems. Corresponding to these electrical and electronic components, electromagnetic compatibility technical requirements put forward in order to increase vehicle safety and reliability, and electromagnetic immunity. Electromagnetic compatibility technology and vehicle emission technology, automotive safety technologies for the automotive technologies. The new European Automotive EMC Directive 2004/104/EC on July 1, 2006 formally promulgated and implemented the directive on the parts and components increased by transient immunity test requirements, reference standards ISO 7637-2, -3.
EMC7637 interference testing equipment in accordance with the development of the International Organization for Standardization ISO7637-2: 2004 and GB/T21437-2008 standards to meet the latest testing requirements for the assessment of electromagnetic compatibility vehicle equipment.

Micro-pulse interference auto simulator （GRP1-2A） specialized electronic equipment for vehicle immunity test, waveform fully meet the ISO-7637-2 （2004 version） standards requirements of P1 and P2A pulse.

Pulse P1 analog shutdown as a result of inductive load （such as windshield wiper motors） have a pulse on other auto electronic products in parallel the impact of voltage, pulse P2A closure occurred in the case of ignition switch, load switch waveforms generated by open-circuit, but also can occur pull-out or fuse in the fuse circumstances。
P1,P2a Technical parameters

Automotive Transient Simulator （GRP3） pulse interference specialized electronic equipment for vehicle immunity test, waveform fully meet the ISO-7637-2 （2004 edition） standard requirements P3 pulse. Pulse P3a automotive electronic systems of all kinds of switches, following the electrical and fuse in the open or closed process, as a result of arc generated by the rapid pulse group （EFT）
P3B pulse was particularly prevalent in the electric doors and windows of the drive unit, speakers, or in the central control door lock system, to simulate the process of switching transients generated interference.
P3a,P3b Technical parameters

Automotive voltage drop simulation generator （GRP2b-P4） specialized electronic equipment for vehicle immunity test, waveform fully meet the ISO-7637-2 （2004 version） P2B standards and requirements P4 pulse. Pulse P2B is the motor running circumstances, ignition switch off arising from a sudden impulse., pulse P4 is the access to large load （such as air-conditioning to open） or to the internal combustion engine to start the electrical power supply system caused by changes in voltage. Built-33V \\ 7 Programmable DC power supply.
P2b,P4 Technical parameters

Car load of high-energy generator throw （GRP-P5b） specialized electronic equipment for vehicle immunity test, waveform fully meet the ISO-7637-2 （2004 version） P standards and requirements P5B pulse, pulse P5 automotive electronic systems most commonly see, but also against a relatively large electromagnetic phenomenon, which causes the generator to the battery charging process of a sudden disconnect the battery （such as the fuse fuse, maintenance suddenly disconnect the battery, etc.） the effect on other electronic equipment voltage pulse, P5b more than P diode clamp.
P,P5b Technical parameters

In addition to these five kinds of typical test waveform, there are more demands from car manufacturers special waveform. We can custom test modules, meet the needs of different enterprise standard auto manufacturers. Reference industry EMC test results, electrostatic discharge testing and transient immunity tests related to automotive safety, and the high probability of electromagnetic phenomena, conduction harassment testing requirements to achieve automotive electronics products, the majority can test through radiation harassment. Hence, we propose a conditional first of all vendors can conduction harassment test systems, electrostatic discharge test system and the ISO 7637 test systems.
