    SOURCE POWER REQUIREMENTS This power supply operates with the installed circuit breaker from 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 34: 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 35: 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 36: Power Supply/Load Interface

    2.7.4 POWER SUPPLY/LOAD INTERFACE The general function of a voltage or current stabilized power supply is to deliver the rated output quantities to the connected load. The load may have any conceivable characteristic: it may be fixed or variable, it may have predominantly resistive, capacitive or inductive parameters; it may be located very close to the power supply output terminals or it may be a considerable distance away.

    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. 2.7.8 and 3.2.14. Users considering series configuration of KLP are urged to contact Kepco Application Engineering first to discuss application details before ordering KLP power supplies intended for Series operation.

  • Page 39: Load Sharing

    For the 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 40: 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 41: 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. 3.2.17.1 to configure internal relay. f.

  • Page 43: 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 44: 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. 3.2.11. NOTE: To eliminate the display of model, virtual model, and protection levels on power-up, refer to PAR.

  • Page 45: 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 46: 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.

    SECTION 4 - CALIBRATION GENERAL This section contains the calibration instructions for the Power Supply. It is recommended that the user be familiar with Local Mode operation (PAR.3.2) before calibrating the unit. A full calibration consist of a voltage calibration and a current calibration. Both voltage and cur- rent calibrations consist of a zero and a full scale calibration.

  • Page 82: Calibration Using Front Panel Controls In Local Mode

    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 to the sense terminals of the shunt resistor.

    9. When the password is accepted, status display reads V ?. Rotating either VOLTAGE or CURRENT control continuously cycles through all the calibration choices. The status display reads: V ? for voltage calibration C ? for current calibration, EXT? for remote analog cali- bration, and EXIT to save the calibrated results.

    4. Tap the DC OUTPUT switch to accept the value. The status display reads CMAX. Rotate the CURRENT control to increase or decrease the DVM reading until the DVM reading corre- sponds as close as possible to (but not less than) the maximum rated current (see Table 1-2) Calculate current as follows: I (Amperes) = DVM reading (Volts) / Shunt Resistance (Ohms).

    During item final test at Kepco, Factory values are established during calibration and are copied to all three locations. Should a unit be returned to Kepco for repair or retest, the recalibration accompanying this testing will overwrite the contents of all three locations with the latest Factory values.

    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 94 How do I view/change the virtual model settings? See PAR. 3.2.9 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.
