The most outstanding features of this Dimension Q-

Series DIN-rail power supply are the high efficiency

and the small size, which are achieved by many novel

design details. The Q-Series is part of the Dimension

family, existing alongside the lower featured C-

Series.

With short-term peak power capability of 150% and

built-in large sized output capacitors, these features

help start motors, charge capacitors and absorb

reverse energy and often allow a unit of a lower

wattage class to be used.

High immunity to transients and power surges as

well as low electromagnetic emission makes usage in

nearly every environment possible.

The integrated output power manager, a wide range

input voltage design and the low input inrush

current make installation and usage simple.

Unique quick-connect spring-clamp terminals allow a

safe and fast installation

A large international approval package for a variety

of applications makes this unit suitable for nearly

every situation.

QS3.241 24V, 3.4A, SINGLE PHASE INPUT Q-Series 26. APPLICATION NOTES 26.1. REPETITIVE PULSE LOADING Typically, a load current is not constant. It varies over time. For pulse load compatibility, following rules must be met: a) b) c) d) The pulse power demand must be below 150% of the nominal power. The duration of the pulse power must be shorter than the allowed Bonus Time. (see output section) The average (R.M.S.) output current must be below the specified continuous output current. If the R.M.S.
PAGE 17
QS3.241 24V, 3.4A, SINGLE PHASE INPUT Q-Series 26.2. PEAK CURRENT CAPABILITY Solenoids, contactors and pneumatic modules often have a steady state coil and a pick-up coil. The inrush current demand of the pick-up coil is several times higher than the steady state current and usually exceeds the nominal output current (including the Bonus Power®) The same situation applies, when starting a capacitive load. Branch circuits are often protected with circuit breakers or fuses.
PAGE 18
QS3.241 24V, 3.4A, SINGLE PHASE INPUT Q-Series 26.5. OUTPUT CIRCUIT BREAKERS Standard miniature circuit breakers (MCBs) can be used for branch protection. Ensure that the MCB is rated for DC voltage, too. The following tests show which circuit breakers the power supply typically trips. Circuit breakers have huge tolerances in their tripping behavior. Therefore, these typical tests can only be used as a recommendation or for comparing two different power supplies.

QS3.241 24V, 3.4A, SINGLE PHASE INPUT Q-Series 26.7. PARALLEL USE TO INCREASE OUTPUT POWER Power supplies can be paralleled to increase the output power. Fig. 26-7 Schematic for parallel operation Unit A AC + - DC + Unit B Load AC + - DC - Instructions for parallel use: a) Use only power supplies from the same series (Q-Series). b) A fuse (or diode) on the output is only required if more than three units are connected in parallel. c) Do not load terminals with more than 25A.

QS3.241 24V, 3.4A, SINGLE PHASE INPUT Q-Series 26.10. SERIES OPERATION The power supply can be put in series to increase the output voltage. Fig. 26-10 Schematic for series operation Unit A AC DC + + Unit B AC DC Load - + - Earth Instructions for use in series: b) It is possible to connect as many units in series as needed, providing the sum of the output voltage does not exceed 150Vdc. c) Voltages with a potential above 60Vdc are not SELV any more and can be dangerous.

QS3.241 24V, 3.4A, SINGLE PHASE INPUT Q-Series 26.14. 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 max. 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.
