  • Page 22: Connecting The Load

    3.9 CONNECTING THE LOAD WARNING Turn Off the AC input power before making or changing any rear panel connection. Ensure all live circuits are discharged and that all connections are securely tightened before applying power. There is a potential shock hazard when using a power supply with a rated output greater than 40V.
  • Page 23 3.9.2 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 cou- pling, which might impact the stability of power supply.
  • Page 24 Fig. 3-11: Remote sensing, single load Fig. 3-12: Multiple loads connection, radial distribution, local sense 3.9.6 Multiple load connection with distribution terminals If remotely located output distribution terminals are used, the power supply output terminals should be connected to the distribution terminals by pair of twisted and/or shielded wires. Each load should be separately connected to the remote distribution terminals (see Fig.3-13).

    -Enabled output, power supply in Constant Voltage mode: Press the PREV button and then ro- tate the CURRENT encoder knob. The CURRENT meter will show the programmed current limit for 5 seconds after the adjustment has been completed, and then will return to show the actual load current.

  • Page 38: Under Voltage Limit (Uvl)

    5.4 UNDER VOLTAGE LIMIT (UVL) The UVL prevents adjustment of the output voltage below a certain limit. The combination of UVL and OVP functions, allow the user to create a protection window for sensitive load circuitry. 5.4.1 Setting the UVL level Setting the UVL can be made when the power supply output is Enabled (On) or Disabled (Off).

    5.11 SAFE START AND AUTO-RESTART MODES When turning on the power supply, it can start to its last setting of Output Voltage and Current limit with the output enabled (Auto-restart) or start with the output disabled (Safe mode). Press and hold the OUT button to select be- tween Safe start and Auto-restart modes.
  • Page 41 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. Set the current limit of each power supply to the maximum that the load can handle without damage.
  • Page 42 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 chained using the Remote-In and Remote-Out connectors.

  • Page 43: 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 remaining units are slaves.

  • Page 44: Daisy-Chain Connection

    With local sensing it is important to minimize the wire length and resistance. Also the positive and negative wire resistance should be as close as possible to each other to achieve current balance between power supplies. 5.16 DAISY-CHAIN CONNECTION It is possible to configure a multiple power supply system to shut down all the units when a fault condition occurs in one of the units.
