    WARNING Some components inside the power supply are at AC voltage even when the On/Off switch is in the “Off” position. To avoid electric shock hazard, disconnect the line cord and load and wait two minutes before removing cover. 3.7.1 AC Input Connector, 1500W models The AC input connector is a 3-Terminal wire clamp located on the rear panel.

    4. Route the AC wires to the input connector terminals as required. To connect the wires, loosen the terminal screw, insert the stripped wire into the terminal and tighten the screw securely (4.4-5.3 Lb-inch). 5. Route the wires inside the cover to prevent pinching. Fasten the cover to the unit using the M3x8 Flat Head screws provided.

    3.8.7 Foldback Check WARNING Shorting the output may expose the user to hazardous voltages. Observe proper safety procedures. Refer to Section 5.5 for explanation of the FOLD function prior to performing the procedure below. 1. Ensure that the Output Voltage is set to approx. 10% of the unit rating. 2.

  • Page 27: Wire Termination

    2. Wire size should be selected to enable voltage drop per lead to be less than 1.0V at the rated current. Although units will compensate for up to 5V in each load wire, it is recommended to minimize the voltage drop (1V typical maximum) to prevent excessive output power consump- tion from the power supply and poor dynamic response to load changes.

  • Page 28: Noise And Impedance Effects

    3.9.4 Noise and Impedance Effects To minimize the noise pickup or radiation, the load wires and remote sense wires should be twisted pairs to the shortest possible length. Shielding of sense leads may be necessary in high noise envi- ronments. Where shielding is used, connect the shield to the chassis via a rear panel Ground screw. Even if noise is not a concern, the load and remote sense wires should be twisted-pairs to reduce coupling, which might impact the stability of power supply.

    5.14 SERIES OPERATION Power supplies of the SAME MODEL can be connected in series to obtain increased output voltage. Split connection of the power supplies gives positive and negative output voltage. CAUTION Do not connected power supplies from different manufacturers in series or in parallel. 5.14.1 Series connection for increased output voltage In this mode, two units are connected so that their outputs are summed.

    3. Programming by external resistor: Programming by external resistor is possible. Refer to Section 6-5 for details. 4. Programming via the Serial The communication port is referenced to the IF_COM Communication port (RS232/RS485): which is isolated from the power supply output potential. Therefore power supplies connected in series can be daisy-chained using the Remote-In and Remote-Out con- nectors.

  • Page 49: Parallel Operation

    5.15 PARALLEL OPERATION Up to four units of the same VOLTAGE and CURRENT rating can be connected in parallel to provide up to four times the Output Current capability. One of the units operates as a Master and the remain- ing units are Slaves.

    CHAPTER 6 REMOTE ANALOG PROGRAMMING 6.1 INTRODUCTION The rear panel connector J1 allows the user to program the power supply Output Voltage and Current with an analog device. J1 also provides monitoring signals for Output Voltage and Output Current. The programming range and monitoring signals range can be selected between 0-5V or 0-10V using the setup switch SW1.
  • Page 54 6.4 REMOTE VOLTAGE PROGRAMMING OF OUTPUT VOLTAGE AND OUTPUT CURRENT CAUTION To maintain the power supply isolation and to prevent ground loops, use an isolated programming source when operating the power supply via remote analog programming at the J1 connector. Perform the following procedure to set the power supply to Remote Voltage programming: 1.
