Bulletin 1606 Switched Mode Power Supplies 22.2 Redundancy Modules 1606-XLSRED40HE – (2x 20A Inputs, 1x 40A output) The redundancy modules in the HE-series are specially designed for power supplies, which feature the HiccupPLUS overload behavior. The1606XLSRED40HE is the preferred redundancy module for the 1606-XLE480EP power supply. It is equipped with two input channels, which are individually decoupled by utilizing mosfet technology.

Bulletin 1606 Switched Mode Power Supplies 23. Application Notes 23.1 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.

Bulletin 1606 Switched Mode Power Supplies 23.2 Back-feeding Loads Loads such as decelerating motors and inductors can feed voltage back to the power supply. This feature is also called return voltage immunity or resistance against Back- E.M.F. (Electro Magnetic Force). This power supply is resistant and does not show malfunctioning when a load feeds back voltage to the power supply. It does not matter whether the power supply is on or off. The maximum allowed feed-back-voltage is 35V DC. 23.
PAGE 21
Bulletin 1606 Switched Mode Power Supplies 23.5 Parallel Use to Increase Output Power Unit A The 1606-XLE480EP power supplies can be paralleled to increase the output power. The output voltage of all power supplies 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 22
Bulletin 1606 Switched Mode Power Supplies 23.7 Series Operation Unit A AC 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 not SELV any more and can be dangerous. Such voltages must be installed with a protection against touching.
PAGE 23
Bulletin 1606 Switched Mode Power Supplies 23.10 Operation on Two Phases The power supply can also be used on two-phases of a three-phase-system. Such a phase-to-phase connection is Power Supply allowed as long as the supplying voltage is below 240V+10%. Use a fuse or a circuit breaker to protect the N input. The N input is internally not protected and is in this case connected to a hot wire. Appropriate fuses or circuit breakers are specified in section “External Input Protection”. 240V +10% max.

Bulletin 1606 Switched Mode Power Supplies 23.12 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. Therefore, two different derating curves for continuous operation can be found below: Curve A1Recommended output current.
