Terminology and Abbreviations
• PE and
symbol-PE is the abbreviation for Protective Earth and has the same meaning as the symbol
• Earth, Ground-This document uses the term "earth" which is the same as the U.S. term "ground".
• T.b.d.-To be defined, value or description will follow later.
• AC 230V-A figure displayed with the AC or DC before the value represents a nominal voltage with standard tolerances (usually ±15%)
included. E.g.: DC 12V describes a 12V battery disregarding whether it is full (13.7V) or flat (10V)
• 230Vac-A figure with the unit (Vac) at the end is a momentary figure without any additional tolerances included.
• 50Hz vs. 60Hz-As long as not otherwise stated, AC100V and AC230V parameters are valid at 50Hz and AC120V parameters are valid at 60Hz
mains frequency.
• may-A key word indicating flexibility of choice with no implied preference.
• shall-A key word indicating a mandatory requirement.
• should-A key word indicating flexibility of choice

  • Page 17: Application Notes

    Bulletin 1606 Switched Mode Power Supplies 26. Application Notes 26.1. Peak Current Capability Solenoids, contactors and pneumatic modules often have a steady state (sealed) coil and a pick-up coil. The inrush current demand of the pick-up coil is several times higher than the steady state curre nt and usually exceeds the nominal output current.

  • Page 18: Series Operation

    Bulletin 1606 Switched Mode Power Supplies 26.3. Series Operation The power supply can be put in series to increase the output voltage. Instructions for use in series: Fig. 26-3 Schematic for series operation It is possible to connect as many units in series as needed,...

  • Page 19: Daisy Chaining Of Outputs

    Bulletin 1606 Switched Mode Power Supplies Please note: This simple way to build a redundant system has two major disadvantages. The faulty power supply cannot be identified. The green LED will still be on since it is reverse-powered from the other power supply.

  • Page 20: External Input Protection

    Bulletin 1606 Switched Mode Power Supplies 26.8. External Input Protection The unit is tested and approved for branch circuits up to 15A (UL) or 16A (IEC). External protection is required only if the supplying branch has an ampacity greater than this. In some countries, local regulations may apply, so check local codes and requirements.

  • Page 21: Mounting Orientations

    Bulletin 1606 Switched Mode Power Supplies 26.12. Mounting Orientations Mounting orientations other than input terminals on the bottom and output on the top 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.
