The LD 5550 (LD = Load Dump Generator) is a plug-in high energy generator module designed for use with the NSG 5500 mainframe system. It is designed primarily to meet the specification requirements for the ISO 7637 standard for pulses 5 and 7. In many cases the specification of this generator exceeds those specified in the ISO 7637 standard.
When slotted into an NSG 5500 mainframe the LD module is fully programmable via USB or RS 232 and IEEE 488 interface. Parameters such as amplitude, pulse frequency, pulse width, are all under program control.
The LD 5550 (and the LD 5505) generates pulses of types 5, and 7, as specified in the ISO 7637 standard, which defines how these pulses are generated in relation to the vehicle battery voltage. When operating with a battery or battery simulator connected to the NSG 5500 mainframe, the CDN 5500 battery switch module should also be mounted in the rear of the NSG 5500 chassis. This module provides the necessary switching on and off of the battery voltage according to the standard.
The module is designed using state of the art active pulse-shaping technology. This means repeatable performance and maintenance free operation. It also means that test results can be repeated accurately.
The output pulses of the generator are available on two 6 mm sockets on the front of the NSG 5500 instrument.
