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

CPS20.121 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.

Additionally, the CPS20.121 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.

CPS20.121 12V, 30A, SINGLE PHASE INPUT C-Series 18. DIELECTRIC STRENGTH The output voltage is floating and has no ohmic connection to the ground. 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. 1.4 DS-CPS20.

It 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 YR80.

CPS20.121 12V, 30A, SINGLE PHASE INPUT C-Series 22. APPLICATION NOTES 22.1. 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.
PAGE 22
CPS20.121 12V, 30A, SINGLE PHASE INPUT C-Series 22.3. EXTERNAL INPUT PROTECTION The unit is tested and approved for branch circuits up to 30A (UL) and 32A (IEC). An external protection is only required if the supplying branch has an ampacity greater than this. Check also local codes and local requirements. In some countries local regulations might apply. If an external fuse is necessary or utilized, minimum requirements need to be considered to avoid nuisance tripping of the circuit breaker.

CPS20.121 12V, 30A, SINGLE PHASE INPUT C-Series 22.5. PARALLEL USE TO INCREASE OUTPUT POWER Unit A CPS20.121 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.
PAGE 24
CPS20.121 12V, 30A, 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. USE IN A TIGHTLY SEALED ENCLOSURE When the power supply is installed in a tightly sealed enclosure, the temperature inside the enclosure will be higher than outside.

CPS20.121 12V, 30A, SINGLE PHASE INPUT C-Series 22.12. 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.
