    9 - Notes on Operation 9. NOTES ON OPERATION Accuracy and Resolution All outputs provide good accuracy and resolution and offer remote sensing to ensure precise regulation at the load. See ‘Technical Specifications’ for accuracy specifications. Remote Sense Each output has a very low output impedance, but this is inevitably increased by the resistance of the connecting leads and the contact resistance between terminals and leads.

  • Page 18: Parallel Wiring Of Outputs

    9 - Notes on Operation Parallel Wiring of Outputs If currents above 6 amps are required, this can be achieved by wiring two or more outputs in parallel. For example, outputs 1 and 2 could be paralleled to provide 42V/12A. In this situation it would be appropriate to use voltage tracking so that the voltage can be adjusted directly on one output.

  • Page 19: Series Wiring Of Outputs

    9 - Notes on Operation Series Wiring of Outputs If voltages above 42 volts are required, this can be achieved by wiring two or more outputs in series. For example, outputs 1 & 2 could be series connected to provide up to 84V. The drawing shows a series connection of two outputs using local or remote sensing.

  • Page 20: Instantaneous Current Output

    9 - Notes on Operation Instantaneous Current Output The current setting control can be set to limit the continuous output current to levels down to the milliamps. However, in common with all precision bench power supplies, a capacitor is connected across the output to maintain stability and good transient response. This capacitor charges to the output voltage and short-circuiting of the output will produce a current pulse as the capacitor discharges which is independent of the current limit setting.

  • Page 21: Over-Temperature Trip (Otp)

    9 - Notes on Operation OCP Trip at Output On If the OCP level is set to a very low level whilst also being below the set current level, it is possible for a trip condition to be created when the output is switched on. This is caused by the current needed to charge the output capacitance.
