RODUCT

ESCRIPTION

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.

ZM2.WALL - W OUNTING RACKET This bracket is used to mount the power supply onto a flat surface without utilizing a DIN rail. Due to the small size of the unit, it is required that the black-DIN rail slide on the back of the unit must be removed. Instructions how to do this can be found in the manual of the ZM2.WALL.

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.

CPS20.121 12V, 30A, 360W, S C-Series INGLE HASE NPUT 23. A PPLICATION OTES 23.1. P URRENT APABILITY 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.

CPS20.121 12V, 30A, 360W, S C-Series INGLE HASE NPUT 23.12. M OUNTING RIENTATIONS 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 Recommended output current.
