GENERAL DESCRIPTION

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.

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 virtually no input inrush

current make installation and usage simple. 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.

QS20.241, QS20.241-A1, QS20.241-C1 24V, 20A, SINGLE PHASE INPUT Q-Series Peak current capability (up to several milliseconds) The power supply can deliver a peak current which is higher than the specified short term current. This helps to start current demanding loads or to safely operate subsequent circuit breakers. The extra current is supplied by the output capacitors inside the power supply. During this event, the capacitors will be discharged and causes a voltage dip on the output.

Type and factory tests are conducted by the manufacturer. Field tests may be conducted in the field using the appropriate test equipment which applies the voltage with a slow ramp (2s up and 2s down). Connect all input-terminals together as well as all output poles before conducting the test.

PHYSICAL DIMENSIONS AND WEIGHT Weight DIN-Rail Installation Clearances 1200g / 2.65lb Use 35mm DIN-rails according to EN 60715 or EN 50022 with a height of 7.5 or 15mm. The DIN-rail height must be added to the unit depth (127mm) to calculate the total required installation depth. See chapter 2 Fig. 20-1 Front view Fig. 20-2 Side view Oct. 2013 / Rev. 2.2 DS-QS20.

YR40 REDUNDANCY MODULES YR40.242 – (2x 20A Inputs, 1x 40A output) The YR40.242 is equipped with two input channels, which are individually decoupled by utilizing mosfet technology. Using mosfets instead of diodes reduces the heat generation and the voltage drop between input and output. The YR40.242 does not require an additional auxiliary voltage and is self-powered even in case of a short circuit across the output.

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.

QS20.241, QS20.241-A1, QS20.241-C1 24V, 20A, SINGLE PHASE INPUT Q-Series 22.2. 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 PowerBoost). The same situation applies when starting a capacitive load. Branch circuits are often protected with circuit breakers or fuses.

(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.

PARALLEL USE TO INCREASE OUTPUT POWER Unit A AC 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) with the same load conditions on all units, or the units can be left with the factory settings.

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.

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.
