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. The same situation applies when starting a capacitive load. Branch circuits are often protected with circuit breakers or fuses.
PAGE 18
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 a) It is possible to connect as many units in series as needed, Unit A providing the sum of the output voltage does not exceed AC 150Vdc. + b) Voltages with a potential above 60Vdc are no longer SELV and can be dangerous. Such voltages must be installed DC with a protection against touching.
PAGE 19
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. - It does not cover failures such as an internal short circuit in the secondary side of the power supply. In such a situation the defective unit becomes a load for the other power supplies and the output voltage can no longer be maintained.

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. If using an external protective device, a minimum value is required to avoid undesired tripping of the fuse. B-Characteristic max. 15A (UL), 16A (IEC) min.
PAGE 21
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. Therefore, two different derating curves for continuous operation can be found below: Curve A1 Curve A2 Recommended output current.
