Load Dump Simulators / Generators
Load Dump Simulators / Generators
Load dump is the electrical occurrence, most commonly in a vehicles, of a battery disconnecting and causing a surge of voltage in an electrical system. The strength of the voltage spike within the system is determined in part by the speed of the alternator at time of disconnection. This electrical occurrence is commonly tested to in automotive standards as there is significant need for systems to be able to withstand such spikes. The most common Automotive EMC Immunity standards that include load dump components would include ISO 7637, SAE J1455GMW3097FMC1278, and many other automotive manufacturer standards. Below you will find the load dump waveform per ISO 7637. Automotive EMC ISO 7637 5a Waveform
We carry load dump test equipment from Teseq and EM Test leaders in automotive EMC Immunity test equipment. The Teseq NSG 5500 is an ideal automotive EMC test equipment solution for testing to many waveforms. This Teseq automotive system includes many programmed standards and requires the PA 5840 power supply. The EM Test LD200N provides the most cost efficient solution allowing for simulating the load dump waveform without paying for unneeded waveform testing capabilities. All of our load dump automotive EMC test equipment comes with an A2LA accredited calibration and technical support. NSG 5500 Teseq Automotive EMC Immunity Generator - Block Diagram

NSG 5500 Rental - Teseq Automotive Transient Immunity Generator System

The NSG5500 made by Teseq offers solutions for transient immunity testing based on ISO 7637 pulses 1, 2a, 3a, 3b, and the load dump pulses from ISO 16750-2.  It includes the +ARB Option for pulses 2b and 4. Our automotive EMI rental equipment includes an accredited calibration in the rental price. The automotive transient immunity generator includes a coupler/battery switch for testing requiring battery coupling.

The NSG 5500 system allows for testing to international, commercial, and company specific standards including. The Arbitrary waveform generator option supports >64,000 segments plus 1GB of Clone data with up to 10Ms/s 16 bit operation. Control of the testing parameters is done through PC running AutoStar™ software. The NSG 5500 Automotive  EMI Test Equipment allows for testing to be completed through a single output connector.

This all-in-one product comes with a laptop with software pre-installed for efficient testing. Additional inputs and outputs are located on the rear panel for test execution control purposes and monitoring. The NSG 5500 is the first product to offer a completely internal 100 amp. battery switch for transient immunity testing. These automotive transient immunity generators can be used with the PA 5840-300 battery Simulator or the PA 5840-75 Battery Simulator.

LD200N Rental - EM Test Automotive EMC Immunity Load Dump Test Equipment

The EM Test LD200n Load Dump Generator allows for testing to SAE J1455, SAE J1113, ISO 7637, wave forms 5 and 7. This Immunity test product simulates the sudden battery disconnection causing an over voltage impulse. A2LA accredited calibration is included in the EMC rental equipment price. This standalone generator includes a 60 V/ 30A DC coupling/decoupling allowing for direct testing.

The Load Dump generator is an all in one system for testing high-energy pulses as required by ISO 7637. By means of a built-in clipping circuit it also generates clipped load dump pulses as per international standards as well as manufacturer requirements. The LD200N can be integrated with the UCS200N and VDS 200N  automotive transient immunity generators for a complete immunity test system, similar to the NSG 5500.  

The LD200N Automotive EMC Test Equipment also allows for both pre-programmed Standard Test and modification of individual pulses through the FreeStyle mode. It has an adjustable source impedance from, 0.5 Ω to 38 Ω in .1 Ω steps. For easy of use we include laptop with software with this rental arriving at your location ready for use.
