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 a

synchronous rectification and further novel design

details.

Large power reserves of 150% support the starting

of heavy loads such as DC motors or capacitive loads.

In many cases this allows the use of a unit from a

lower wattage class which saves space and money.

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 and virtually

no input inrush current make installation and usage

simple with no jumpers and switches necessary.

Diagnostics are easy due to the dry DC-ok contact, a

green DC-ok LED and red overload LED.

Unique quick-connect spring-clamp terminals allow a

safe and fast installation and a large international

approval package for a variety of applications makes

this unit suitable for nearly every situation.

QT20.241, QT20.241-C1 24V, 20A, THREE PHASE INPUT Q-Series 27. APPLICATION NOTES 27.1. 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) e) 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.
PAGE 18
QT20.241, QT20.241-C1 24V, 20A, THREE PHASE INPUT Q-Series 27.2. 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 19
QT20.241, QT20.241-C1 24V, 20A, THREE PHASE INPUT Q-Series 27.5. 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.

QT20.241, QT20.241-C1 24V, 20A, THREE PHASE INPUT Q-Series 27.6. EXTERNAL INPUT PROTECTION The unit is tested and approved for branch circuits up to 15A (U.S.A.) and 16A (IEC). External protection is only required, if the supplying branch has an ampacity greater than this. In some countries local regulations might apply. Check also local codes and local requirements. If an external fuse is necessary or utilized, a minimum value is required to avoid undesired tripping of the fuse. B-Characteristic max.

Fig. 27-10 Schematic for parallel operation Unit A Fuse *) AC + - DC Unit B Fuse *) AC + - DC + Load - Instructions for parallel use: a) Use only power supplies from the same series (Q-Series). b) Adjust the output voltages of all power supplies to approximately the same value (±500mV).

QT20.241, QT20.241-C1 24V, 20A, THREE PHASE INPUT Q-Series 27.11. SERIES OPERATION The power supply can be put in series to increase the output voltage. Fig. 27-13 Schematic for series operation Unit A AC DC + + Unit B Load AC DC + - Earth (see notes) Instructions 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. b) Voltages with a potential above 60Vdc are not SELV any more and can be dangerous.

QT20.241, QT20.241-C1 24V, 20A, THREE PHASE INPUT Q-Series 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.
