GENERAL DESCRIPTION

The most outstanding features of the DIMENSION Q-

Series DIN-rail power supplies are the extremely high

efficiencies and the small sizes, which are achieved by a

synchronous rectification and other technological

designs.

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, the three input

fuses and near zero input inrush current make

installation and usage simple. Diagnostics are easy due

to the DC-ok relay, a green DC-OK LED and the red

overload LED.

A large international approval package for a variety of

applications makes this unit suitable for nearly every

application.

QT40.241 24V, 40A, THREE PHASE INPUT Q-Series 26. APPLICATION NOTES 26.1. REPETITIVE PULSE LOADING Typically, a load current is not constant and varies over time. This power supply is designed to support loads with a higher short-term power demand (=BonusPower®). The short-term duration is hardware controlled by an output power manager and is available on a repeated basis.
PAGE 22
QT40.241 24V, 40A, THREE PHASE INPUT Q-Series 26.2. 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.

QT40.241 24V, 40A, THREE PHASE INPUT Q-Series 26.4. USING ONLY 2 LEGS OF A 3-PHASE SYSTEM L1 L2 L3 PE No external protection devices are required to protect against a phase-loss failure. This power supply can also be permanently operated on two legs of a 3phase system. However, it is not recommended for this power class since the supplying 3-phase network can become unbalanced.

QT40.241 24V, 40A, THREE PHASE INPUT Q-Series 26.5. CHARGING OF BATTERIES The power supply can be used to charge lead-acid or maintenance free batteries. (Two 12V batteries in series) Instructions for charging batteries: a) Set output voltage (measured at no load and at the battery end of the cable) very precisely to the end-of-charge voltage. End-of-charge voltage 27.8V 27.5V 27.15V 26.

QT40.241 24V, 40A, THREE PHASE INPUT Q-Series 26.7. PARALLEL USE TO INCREASE OUTPUT POWER Power supplies from the same series (Q-Series) can be paralleled to increase the output power. The output voltage 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. After the adjustments, the jumper on the front of the unit shall be moved from “Single use” to “Parallel use”, in order to achieve load sharing.
PAGE 26
QT40.241 24V, 40A, THREE PHASE INPUT Q-Series 26.9. SERIES OPERATION 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.

QT40.241 24V, 40A, THREE PHASE INPUT Q-Series 26.13. 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 A1 Curve A2 Recommended output current.
