    NOTE 3. The concept of “box value” is illustrated above. It is an area around the origin, where the limits of the unit (voltage or current) cannot be programmed. This minimum (box) value for the positive limits or maxi- mum (box) value for the negative limits, is a model dependent constant of approximately 0.2% of the nominal values for voltage and current.

    2.5.5 LOAD CONNECTION - GENERAL Load connections require wires that are properly rated for the nominal output current of the unit. Load connections to the BOP power supply are achieved via the OUTPUT and COMMON bus bar-type terminals located on the rear panel. A barrier strip is provided at the rear panel for con- nection of the sense wires to the load (for remote sensing or multiple unit applications).

  • Page 55: Setting Up The Unit

    SETTING UP THE UNIT The following paragraphs describe the connections and initial BOP setup needed to operate in the desired mode. 2.7.1 CONSIDER THE LOAD TYPE The BOP can be configured to respond differently to the Output OFF command, depending on whether the load is defined as Active, Resistive or Battery.

    3.3.3.1 SELECTING BIPOLAR/INDEPENDENT PROTECTION LIMITS The BOP can be configured to allow the protection limits to be displayed and changed from the front panel as either a single value that applies to both protection channels or as individual set- tings for positive and negative protection limits. Selecting Independent protection limits means that the positive and negative limits are displayed (and can be modified) independently.

  • Page 94: Understanding Voltage And Current Protect Limits

    Selection of Bipolar does not immediately change the protect limit values; it changes how the protect settings are displayed and set from the power-up screen. So if maximum/minimum pro- tection limits were set to different values, (e.g, for BOP 36-28MG, current mode, no load, +V Protect Max = 25V and –V Protect Min = 7V) when Bipolar is selected, the previous protection values (+25, –7) will remain in place until a new value is entered in the Voltage Protection field.

    3.6.3.10 CALIBRATE SUBSYSTEM The BOP series of power supplies support software calibration. A full calibration consist of a voltage calibration and a current calibration. These calibration procedures include steps that prepare the unit for series or parallel operation. Both voltage and current calibrations consist of a zero (performed on the main channels only) and positive and negative full scale calibrations with both internal and external references.

    3.6.7.1 STATUS REPORTING STRUCTURE The status reporting of the BOP uses four status registers, illustrated in Figure 3-29. These reg- isters are the Questionable, Operation, Standard Event Status and Status Byte registers. The Questionable and Operation registers are 16 bit registers and the Standard Event Status and Status Byte registers are 8 bits.

A bit set in the QUEStionable condition register indicates that the data currently being acquired or generated is of questionable quality due to some condition affecting the parameter associ- ated with that bit.

    (together) TEST EQUIPMENT REQUIREMENTS Table 4-2 lists sense resistors recommended for measuring current and includes Kepco and Manufacturer’s part numbers. The value of the sense resistor chosen should be known with 0.001% accuracy. If other than a recommended sense resistor is to be used, it must be rated for at least 100W power dissipation (actual power dissipation will be approximately 10W).

    NOTE: Selected sense resistor must be mounted on a heatsink with a minimum surface area of 36 square inches to maintain ther- mal stability during calibration; forced cooling is recommended. Kepco Heatsink P/N 136-0451 will provide adequate cool- ing for the sense resistor.
