    SOURCE POWER REQUIREMENTS This power supply operates with the installed circuit breaker from either d-c or single phase a-c mains power over the voltage and frequency ranges specified in Table 1-3 without adjustment or modification. COOLING The power devices used within the power supply are maintained within their operating tempera- ture range by means of internal heat sink assemblies cooled by three internal (d-c type) cooling fans.

    • Then the status display reads SET (setpoint mode), the DC VOLTS display reads 0 Volts, the DC AMPERES display reads minimum Amperes (see Note 1, below). NOTES: 1. A minimum programmed current (actual value depends on model) is required to ensure proper operation of the power supply under all load conditions.

  • Page 32: Safety Grounding

    It is the user's responsibility to ensure that all applicable local codes for source power wiring are met. Kepco also makes a variety of prefabricated safety line cord sets available for connecting KLP to source power via conven- tional box-mounted receptacles.

  • Page 33: D-C Output Grounding

    It is hoped that the preceding paragraphs will be of some assistance in most cases. For help in special applications or difficult problems, consult directly with Kepco's Application Engineering Depart- ment.

  • Page 34: Power Supply/Load Interface

    Voltage models (75V, 150V, 300V, 600V) employ Euroblock-style terminal blocks that accept bare wire ends. Where discrete wires are used for the load connection, Kepco strongly recommends the use of stranded (not solid) wire with (+) and (–) wires tightly twisted to reduce self-inductance; wire end ferrules are suggested to prevent fraying of the strands.

  • Page 35: Series Operation

    Figure 2-4 shows a series connection of two KLP power supplies using remote sensing. Kepco strongly recommends that series applica- tions employ master/slave control (available on standard models only) as described in PAR’s.

  • Page 37: Load Sharing

    For low-voltage models (10V, 20V, 36V) Kepco advises the use of bus bar conductors where possible; for higher voltage models (75V - 600V), appropriately sized twisted conductor pairs terminated with wire ferrules are recommended (contact Kepco Applications Engineering for details).

  • Page 38: Master/Slave Configurations [Standard Models Only]

    If GPIB control of the master/slave pair is desired, the user must connect to the master unit using an “in-line” style connector, as the commonly-used stackable connector will interfere phys- ically with the RS 232 connector above it. Contact Kepco Sales Engineering for additional guid- ance.

  • Page 39: Digital Connections

    e. Fault Connections (RELAY_NC, RELAY_COM, RELAY_NO It is recommended that normally open and normally closed relay signals RELAY_NC (pin 10) and/or RELAY_NO (pin 2), respectively, be twisted together with RELAY_COM (pin 4) as needed to eliminate noise pickup. See PAR. 3.2.16.1 to configure internal relay. f.

  • Page 41: Section 3 - Operation

    SECTION 3 - OPERATION GENERAL This section explains how to operate the KLP Power Supply. Series KLP feature three modes of operation: • Local Mode (see PAR. 3.2): This is the default operating mode, providing full access to all programming and readback functions via front panel displays, controls, and indica- tors.

  • Page 42: Power-Up Built-In Test Error Codes

    • Status display flashes PROT for 2 seconds while DC VOLTS and DC AMPERES dis- plays show previously stored OVP and OCP trigger levels. NOTE: to reprogram OVP or OCP, refer to PAR. 3.2.10. NOTE: To eliminate the display of model, virtual model, and protection levels on power-up, refer to PAR.

  • Page 43: Setting Local/Remote Mode

    NOTE: A minimum programmed current is required to ensure proper operation of the power supply under all load conditions. Programmed current is automatically set to be at least the minimum current (actual value depends on model, see Table 1-2). • Since the output is off, Constant Voltage (CV) mode indicator (green LED) and Con- stant Current (CC) indicator (amber LED) are off.

  • Page 44: Remote With Local (Front Panel) Lockout

    3.2.2.1 REMOTE WITH LOCAL (FRONT PANEL) LOCKOUT To prevent unauthorized setting of the power supply to Local mode, a local lockout mode can be enabled which prevents the power supply from being restored to local mode via the front panel. With the power supply turned off, set the ANALOG I/O DIP switch, position 5 (see Table 2-2) to ON.

    3.2.9.1 REAL-TIME VOLTAGE/CURRENT ADJUSTMENT Rotating the associated control will change the output voltage or current in real-time only if the output is enabled. If the unit is in constant voltage mode (CV indicator lit) the DC VOLTS display shows the actual output voltage as the VOLTAGE control is rotated. Similarly, if the unit is in constant current mode (CC indicator lit) the DC AMPERES display shows the actual output cur- rent as the CURRENT control is rotated.

    CALIBRATION USING FRONT PANEL CONTROLS IN LOCAL MODE For voltage calibration all loads must be disconnected and the sense terminals connected to the corresponding output terminals. The digital voltmeter will be connected to the output of the power supply. For current calibration after disconnecting all loads an appropriate shunt resistor will be connected across the output terminals and the digital voltmeter will be connected across the sense terminals of the shunt resistor.

    the DVM reads as close as possible to (but not less than) the rated model voltage (e.g., 75V for KLP 75-33). 3. Tap the DC OUTPUT switch to accept the value; the status display now reads OUTV. At the ANALOG I/O PORT J2, connect the DVM (M– to pin 13, M+ to pin 6) and the d-c power source (V–...

    NOTE: The full scale programming voltage has a 1:1 correspondence with the external read- back; i.e., 10V full scale programming voltage results in a 10V full scale readback. If the full scale programming voltage is changed to a value other than 10V, the full scale readback voltage is changed accordingly.

    1. Click the CURRENT button on the Calibration Window to start current calibration; the Cur- rent Calibration Window (Figure 4-3) appears and the status display on the VXI main panel reads CMAX. FIGURE 4-3. CURRENT CALIBRATION WINDOW 2. Monitor DVM and click the “+” button to increase and the “–“ to decrease the output current until the DVM reads as close as possible to maximum rated current (Calculate current as fol- lows: I (Amperes) = DVM reading (Volts) / Shunt Resistance (Ohms).

    4.4.3 ANALOG REFERENCE CALIBRATION (VXI plug&play DEMO) During analog reference calibration the external analog reference voltages used to establish full scale output current and voltage are defined. The factory default calibration of 10V programs full scale output, however the following procedure allows any d-c value up to 10V to program full scale, while a voltage proportionately less programs a corresponding decrease in the output.

  • Page 89: Restoring Prior Calibration Values

    Calibration values for KLP are stored in three separate locations in flash memory designated: Factory, Prior and Working. Factory values are established during item final test at Kepco and cannot be altered by the user. Each time the unit is calibrated, the Working values are moved to Prior, and the new calibration values are stored in Working.

    4. Connect power supply to power source using one of the following: See PAR. 2.7.2 for additional information. • Use standard NEMA line cord set from Kepco (see Table 1-5) or customized line cord using user-wireable mating connector (supplied) in conjunction with user-selected line cord or discrete wiring as applicable.
  • Page 92 How do I view/change the virtual model settings? See PAR. 3.2.8 for description of virtual model. If status shows SET, exit set- point mode (tap either knob once). Use thin tool to press FUNCTION once; status reads VIRT. VOLTS and AMPS displays show the maximum voltage and current of the present virtual model.
