GENERAL DESCRIPTION

The Dimension C-Series are cost optimized power

supplies without compromising quality, reliability and

performance. The C-Series is part of the DIMENSION

power supply family. The most outstanding features of

CPS20.241 are the high efficiency, electronic inrush

current limitation, active PFC, wide operational

temperature range. The small size is achieved by a

synchronous rectification and further technological

design details.

The C-Series includes all the essential basic functions.

The devices have a power reserve of 20% included,

which may even be used continuously at temperatures

up to +45°C. Additionally, the CPS20.241 can deliver

about 4 times the nominal output current for 15ms

which helps to trip fuses on faulty output branches.

High immunity to transients and power surges as well as

low electromagnetic emission, a DC-OK relay contact

and a large international approval package for a variety

of applications makes this unit suitable for nearly every

situation.

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 1000g / 2.2lb 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 Apr. 2014 / Rev. 1.6 DS-CPS20.

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.

PEAK CURRENT CAPABILITY The unit 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.

CPS20.241, CPS20.241-C1 24V, 20A, SINGLE PHASE INPUT C-Series 22.2. BACK-FEEDING LOADS Loads such as decelerating motors and inductors can feed voltage back to the power supply. This feature is also called return voltage immunity or resistance against Back- E.M.F. (Electro Magnetic Force). This power supply is resistant and does not show malfunctioning when a load feeds back voltage to the power supply. It does not matter whether the power supply is on or off.

CPS20.241, CPS20.241-C1 24V, 20A, SINGLE PHASE INPUT C-Series 22.5. PARALLEL USE TO INCREASE OUTPUT POWER CPS20.241 power supplies can be paralleled to increase the output power. The output voltage of all power supplies 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.

CPS20.241, CPS20.241-C1 24V, 20A, SINGLE PHASE INPUT C-Series Unit A 22.7. SERIES OPERATION AC 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.

Such a phase-to-phase connection is allowed as long as the supplying voltage is below 240V+10%. L3 AC L Fuse L2 internal fuse N PE DC 22.11.

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.
