•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.

• 3AC 400V—A figure displayed with the AC or DC before the value represents a nominal voltage with standard tolerances (usually ±15%)

included. 3AC means three phase input. E.g.: DC 12V describes a 12V battery whether it is charged (13.7V) or discharged (10V).

Unless otherwise stated, 3AC 400V parameters are valid at 50Hz and 3AC 480V parameters are valid at 60Hz mains frequency.

• 3x 400Vac—A figure with the unit (Vac) at the end is a value used during testing without any additional tolerance included. 3AC means three

phase input.

The DIN rail height must be added to the depth (157mm) to calculate the total required installation depth. Fig. 21-1 Front view Fig. 21-2 Side view 22. Installation and Operating Instructions Mounting and installation: Output terminal must be located on top and input terminal on the bottom.

Bulletin 1606 Switched Mode Power Supplies 23. Accessories Buffer Module 1606-XLSBUFFER48 This buffer unit is a supplementary device for DC48V power supplies. It delivers power to bridge typical mains failures or extends the hold-up time after turn-off of the AC power. At times when the power supply provides sufficient voltages, the buffer unit stores energy in integrated electrolytic capacitors. In case of mains voltage fault, this energy is released again in a regulated process. Fig.

Bulletin 1606 Switched Mode Power Supplies 25. Application Notes 25.1. Periodical Peak Power Capability Fig. 25-1 Periodical peak power capability POUT PNOM TP The short term power can be used periodically. The duration of the peak power (TP ) must be shorter than 15s. The time between two peak power pulses must be three times longer than the duration of the preceding pulse length. T > 3x T P 125% 100% t 25.2. Charging of Batteries The power supply shall not be used to charge batteries.

Bulletin 1606 Switched Mode Power Supplies 25.3. Output Circuit Breakers Standard miniature circuit breakers (MCBs or UL 1077 supplementary breakers) can be used for branch protection but make sure that the MCB is rated for DC voltage as well. The following tests show which circuit breakers the power supply will typically trip. Circuit breakers have huge tolerances in their tripping behavior. These typical tests can therefore be used only as a recommendation or for comparing two different power supplies.
PAGE 19
Bulletin 1606 Switched Mode Power Supplies 25.4. External Input Protection The power supply does not include any internal input fuse. The unit is tested and approved for branch circuits up to 16A (U.S.A 15A). External protection is required o n l y i f the supplying branch has an ampacity greater than this. In some countries local regulations might apply; do check all local codes and requirements.

Bulletin 1606 Switched Mode Power Supplies 25.8. Series Operation Power supplies from the 1606-XLE family can be used in series to increase output voltage. Fig. 25-4 Schematic for series operation Unit A AC DC + + Unit B Load AC DC + - Earth (see notes) Installation notes for use in series: a) It is possible to connect as many units in series as needed, providing the sum of the output voltage does not exceed 150Vdc.
PAGE 21
Bulletin 1606 Switched Mode Power Supplies 25.12. 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.
