  • Page 21: Application Notes

    Bulletin 1606 Switched Mode Power Supplies 25. Application Notes 25.1. Repetitive Pulse Loading Typically, a load current is not constant and varies over time. This power supply is designed to support loads with a higher short-term power demand (=BonusPower). The short-term duration is hardware controlled by an output power manager and is available on a repeated basis.

  • Page 22: Peak Current Capability

    Bulletin 1606 Switched Mode Power Supplies 25.2. Peak Current Capability The power supply can deliver peak currents (up to several milliseconds) which are higher than the specified short term currents. This helps to start current demanding loads. Solenoids, contactors and pneumatic modules often have a steady state coil and a pick-up coil.

  • Page 23: Using Only 2 Legs Of A 3-Phase System

    Bulletin 1606 Switched Mode Power Supplies 25.4. Using Only Two Legs of a 3-Phase System No external protection devices are required to protect against a phase-loss Power Supply failure. This power supply can also be permanently operated on two legs of a 3- phase system.

  • Page 24: Charging Batteries

    Bulletin 1606 Switched Mode Power Supplies 25.5. Charging Batteries The power supply can be used to charge lead-acid or maintenance free batteries. (Two 12V batteries in series.) Instructions for charging batteries: Set output voltage (measured at no load and at the battery end of the cable) very precisely to the end-of-charge voltage.

  • Page 25: Parallel Use To Increase Output Power

    Bulletin 1606 Switched Mode Power Supplies 25.7. Parallel Use to Increase Output Power Power supplies from the 16060-XLS series can be paralleled to increase Unit A the output power. The output voltage shall be adjusted to the same value (±100mV) in “Single use” mode with the same load conditions on all units, or the units can be left with the factory settings.

  • Page 26: Series Operation

    Bulletin 1606 Switched Mode Power Supplies 25.9. Series Operation Unit A Power supplies of the same type can be connected in series for higher output voltages. It is possible to connect as many units in series as needed, providing the sum of the output voltage does not exceed 150Vdc. Voltages with a potential above 60Vdc are no longer SELV and can be dangerous.

  • Page 27: Mounting Orientations

    Bulletin 1606 Switched Mode Power Supplies 25.13. Mounting Orientations Mounting orientations other than all terminals on the bottom require a reduction in continuous output power or a limitation in the maximum allowed ambient temperature. The amount of reduction influences the lifetime expectancy of the power supply.
