  • Page 49: Connecting Single Loads, Remote Sensing

    3.9.8 Connecting Single Loads, Remote Sensing Fig.3-11 shows recommended remote sensing connection for single loads. Remote sensing is used when, in Constant Voltage mode, the load regulation is important at the load terminals. Use twisted or shielded wires to minimize noise pick-up. If shielded wires are used, the shield should be connected to the ground at one point, either at the power supply chassis or the load ground.

  • Page 50: Multiple Load Connection With Distribution Terminals

    3.9.10 Multiple Load Connection with Distribution Terminals If remotely located output distribution terminals are used, the power supply output terminals should be connected to the distribution terminals by pair of twisted and/or shielded wires. Each load should be separately connected to the remote distribution terminals (see Fig.3-13).

  • Page 51: Local Sensing

    3.10.2 Local sensing The power supply is shipped with the rear panel J2 sense connector wired for local sensing of the Output Voltage. See Table 3-4 for J2 terminals assignment. With local sensing, the Output Voltage regulation is made at the output terminals. This method does not compensate for voltage drop on the load wires, therefore, it is recommended only for low load current applications or where the load regulation is less critical.

    7.9.1 Fast Test for Connection This is an addressed query that is good for scanning to see what supplies are “on line”. If no response is returned within 10 mSec, your control program has determined that no power supply is connected at that address. Query Format: Send two bytes of unreadable characters.

    7.9.3 Read Power-On Time This query allows you to read how many minutes the power supply has been running since it was built. The accuracy, in minutes, is not guaranteed for time critical applications. Query Format: Send two bytes of unreadable characters. First: Byte 1 = 1010 0110 = A6 hex Byte 2 = 000x xxxx (where xxxxx is the address of the supply in binary)

    8 ISOLATED ANALOG PROGRAMMING OPTION Introduction Isolated Analog Programming is an internal Option Card for analog programming of the Genesys™ power supply series. The option is factory installed and cannot be obtained with a GPIB (IEEE-488) Interface. Output Voltage and Output Current can be programmed and readback through optically isolated signals which are isolated from all other ground references in the power supply.

  • Page 101: Fuse Rating

    Fuse Rating There are no user replaceable fuses in the power supply. Internal fuses are sized for fault protection and if a fuse was opened, it would indicate that service is required. Fuse replacement should be made by qualified technical personnel. Refer to Table 9-2 for a listing of the fuses.
