User Manual 2.10 Parallel Operation Two or more KDC power supplies of the same voltage range may be combined to create a higher power system. This requires one master unit (default) and one or more auxiliary units (-AUX). If both units have the same power level (same model numbers), the sharing will be equal between the chassis and the programmed current limit set on the master will be multiplied.
Page 18: Available Options And Accessories
User Manual 2.11 Available Options and Accessories The following factory installed options are available for the KDC II series and may be specified at the time of order. Installed options are shown on the model and serial tag of the KDC power supply.
Page 19: Lc Option
User Manual 2.12 -LC Option The –LC option has been replaced by the –FT option. 2.13 -FT Option The –FT option provides a high current bleeder and reduces the output capacitance of each DC power module to support faster down programming times. This results in further improved fall times compared to a standard KDC unit.

Page 47: Table 4-2: Transient Programming Resolution From Front Panel
User Manual the right hand knob (CURRENT) is used to increment or decrement the parameter value. The left-hand knob (VOLTAGE) is used to increment or decrement the list point sequence number (#). The sequence number can only be increased to the next available empty (new) list point. To move to the next or previous parameter, use the UP ( ) or DOWN ( ) cursor keys The voltage and current slew parameters can be set to their maximum slew rates by turning the CURRENT knob counter clock-wise past 0.
Page 48 User Manual Setting Slew Rates Very often, output changes must be done as fast as the DC supply can make them. This means the transient list slew rate is set to its maximum value. If this is the case for all the data points in the list, it is sufficient to set just the first data point's slew rate for either voltage and/or current.
Page 49 User Manual 4.2.7 Registers Menu The registers menu provides access to the non-voltage setup storage of the DC power supply. A total of 8 front panel setups can be stored in registers numbered from 0 through 7. Each register can hold the complete front panel setup, including the programmed transient list. This allows for quick recall of different setups and transient programs.

Page 63: Mode Status
User Manual 4.6 Mode Status The KDC Series can operate in one of two modes of operation, voltage mode or current mode with automatic cross over. Mode Description Voltage Mode (CV) mode Constant voltage mode. The supply maintains the set voltage. If the current limit is exceeded, the output trips off.
Page 64: Figure 4-7: Constant Power Mode Profile
User Manual 4.6.1 Constant Power mode operation profile The constant power mode attempts to maintain constant power into the load. This concept is bound by the voltage and current mode limitations however. Thus, it may not be possible to maintain constant power mode under all load conditions. For example, if the required voltage to maintain constant power exceeds the programmed (set) voltage, the power supply will revert to CV mode once the maximum voltage is reached and the output power will be less than set in the POWER field of the CP mode screen.
Page 65: Remote Sensing
User Manual 4.7 Remote Sensing In applications where the load is located some distance from the power supply, or the voltage drop of the power output leads significantly affects load regulation, remote voltage sensing may be used. When remote sensing is used, voltage is regulated at the load versus the power supply output terminals.
Page 66: Remote Output On / Off Control
User Manual 4.8 Remote Output ON / OFF Control Remote on/off (remote inhibit) control may be accomplished by contact closure or TTL/CMOS voltage source. The output will remain OFF while the remote inhibit state is active. Once removed, the output will resume the state (on or off) that was in effect when the remote inhibit was applied.

User Manual 2. External Voltage Programming using a resistor. The resistance coefficient for remote voltage programming is 5k ohms/100% of rated output voltage with respect to the (ISO VP/IP RTN), pin 6. The programming current from pin 13 (VP RES) is 1 milliamp through a 5 V DC supply.
Page 70: Figure 5-4: Remote Current Programming Using 0-5 Or 0-10 Vdc Source
User Manual 5.1.2 Remote Current Programming The remote current programming is used for applications that require the output current be programmed (controlled) from a remote source. An external resistance or external voltage source may be used as a programming device. When using remote current programming, a shielded, twisted-pair, hookup wire is recommended to prevent noise interference with programming signals.
Page 71: Figure 5-5: Remote Current Programming Using Resistance
User Manual 2. External Current Programming Using Resistance. The resistance coefficient for remote current programming is 5k ohms/100% rated output with respect to pin 6 (ISO VP/IP RTN). The programming current from PIN 5 (IP RES) is factory set for 1 milliamp. This yields a coefficient of 1.0% of rated output current for each 50 ohms.
Page 72: Multi Unit Configurations
User Manual 5.2 Multi Unit Configurations The following modes of operation are used for applications requiring more current or voltage than is available from a single power supply. To meet the requirements for greater output voltage or current, two supplies may be connected in series or parallel. This requires the –IF analog interface option.

User Manual 7.6 Non-Routine Calibration The following calibrations are not required on a routine basis: 7.6.1 VOLT NOM Adjustment Since the KDC controller is used for all output voltage range models, the internal reference signals are normalized for each model using calibration DAC's. This normalization is generally done at the factory and does not have to be repeated unless a power module has been replaced in the field.

This normalization is generally done at the factory and does not have to be repeated unless a power module has been replaced or added to an existing unit in the field.

User Manual 8 Service 8.1 General This section describes suggested maintenance and troubleshooting procedures. The troubleshooting procedure is divided into two sections. The first section deals with basic operation and connection of the equipment. The second section requires opening the unit and using the LED indicators and a simple multimeter to troubleshoot the unit down to the module level.
