  • Page 3: Introduction

    1. INTRODUCTION Congratulations with your purchase of LEM IST ULTRASTAB. The IST ULTRASTAB unit serves as power supply and signal processing unit for up to 6 individual LEM IT/ITN ULTRASTAB current transducer units. It ensures that the extremely high precision and low noise offered by the transducers is preserved and made available in a convenient and user-friendly unit.

  • Page 7: System Description

    In basic terms, the IST ULTRASTAB can drive up to six channels at a total (summed) current consumption of 6.6 A.

    5.1 FRONT PANEL The front panel includes indicators for each transducer channel. FIGURE 1: An overview of the front panel, with a close-up of the indicator panel 5.2 INDICATOR PANEL The illuminated indicator panel has seven fields that are lit in the following modes: POWER: •...

  • Page 9: Back Panel

    IMPORTANT: The IST ULTRASTAB unit has NO breaker for switching mains on and off. Power is supplied to the unit once the mains cable is inserted into the mains inlet and mains are switched on at the outlet.

  • Page 10: Connecting The Transducers

    5.5 CONNECTING THE TRANSDUCERS The IST ULTRASTAB rack provides 6 9-pin D-Sub connectors on the back panel for connecting up to 6 IT/ITN individual transducers. Each 9-pin D-Sub connector is used to connect the supply voltage to the DC power input of the transducer.

  • Page 11: Output Port

    To prevent any malfunction that may occur due to the cable/wire voltage drop (i.e., its length and the wire resistance inside the cable) between the IST ULTRASTAB rack and the transducer, a cable with at least 7 wires, each having a cross section AWG 22, AWG 23 or ≥ 0.25 mm², must be used.

  • Page 12: Figure 7: Status/Interlock Port Wiring

    All LEM IT/ITN ULTRASTAB current transducers generate a status signal, which contains information about the operational status of the unit. This signal is routed through the IST ULTRASTAB and available in one 15-pin D-Sub male connector containing status signals for all 6 channels.

  • Page 13: Figure 8: Pinout For 15-Pin Status Connector

    In the diagram A, the active low output signal V switches to GND when the corresponding transducer is OK (Normal operation and Green LED is lit). In the same manner, the transistor is switched off (No current from collector to emitter) to indicate that the corresponding transducer is not OK.

  • Page 14: Installation

    IMPORTANT: The IST ULTRASTAB is passively cooled by airflow entering the perforated areas in top, sides and bottom of the cabinet. Make sure that these holes are not blocked as this will severely affect the performance of the unit.

  • Page 15: Operating Instructions

    7. OPERATING INSTRUCTIONS When instructions for installation are complete, the IST ULTRASTAB can be switched ON. Apply mains power by inserting the cable plug in the mains inlet and switching on mains at the outlet. The green indicator LED “Power” will be lit.
