JT 5510 & JT 5550

The JT 5510 and JT 5550 are plug-in transient generator modules designed for use with the NSG 5500 mainframe system. This generator is designed to meet the specifi cation requirements for the JASO D-001-94 standard for pulses A1, A2, B1, B2, D1, D2, E and similar.

The JT 5510 and JT 5550 utilize the exclusive Teseq Gemini features for ultimate fl exibility of your NSG 5500 system.

When operating with a battery or battery simulator connected to the NSG 5500 mainframe, the NSG 5500 Battery Switch Module should also be mounted in the rear of the NSG 5500 chassis. For best results, these modules should be installed in the main NSG 5500 chassis with no expansion chassis. This module provides the necessary switching on and off of the battery voltage as specifi ed in the standard. Alternatively, for greater than 25 A of battery current, the main EUT Output may be used.

When slotted into an NSG 5500 mainframe the transient generators are fully programmable either via RS232 or IEEE 488 interface. Parameters such as ampli-tude, and pulse repetition may be programmed per the user’s needs.

The JT 5510 and JT 5550 are designed using state of the art semi-conductor tech-nology. This means repeatable performance and maintenance free operation. It also means that test results can be repeated with a high degree of accuracy.

The output pulses of the generator are available on two power banana sockets on the front of each module.

The JT 5510 and JT 5550 contain the proper selection of different internal output resistances.

1 INTRODUCTION

5The AutoStar software program, available from Teseq, is a Windows based graphical program that allows full control of all programmable features via an intuitive graphical windows front panel.

Check the instrument for any mechanical damage. Report any damage found to the carrier immediately.

Ensure that the power is turned off on the NSG 5500 mainframe and that the battery input is disconnected. Insert JT 5510 cassette in the left slot and the JT 5550 in the right slot and push in fully. Screw in the four retaining screws fully.

It is vitally important that the unit mains power is connected to protective earth.

Turn on the mains input power on the NSG 5500 mainframe. After approximately a two second delay the power LED (red) on the JT 5510 or JT 5550 generator should light. After a further two-second initialisation period, the unit is ready for operation.

The scope test set-up shown in 4.1 should be connected and the output pulses should be quickly checked to ensure that they are of the correct form and shape. As pulses are generated ‘Fire’ LED should light briefly.

When the battery voltage and correct operation has been verified, the DUT can be connected to the OUTPUT terminals at the front of the unit, and the required tests can be carried out.

DuetothefastrisetimesandsometimeshighRioftheJASOpulses, it isstronglyrecommendedtoconnectdirectly to the OUTPUT connector of the applicablemodulefortestingandpulseverification.

4.1Testset-upThe following set-up may be used to check the integrity of the output pulses. The scope probe should allow measurement of pulse voltages of up to 600 V peak, input impedance of >10 kΩ at a frequency of >2 MHz. Note: it is very important to compensate the probe in advance. Because of the exponential shape of the transients, an uncompensated probe will cause errors on rise time and voltage measurement, and an incorrect pulse shape.
