GENERAL DESCRIPTION

The Dimension C-Series are cost optimized power

supplies and DC/DC converters without compromising

quality, reliability and performance. The C-Series is part

of the DIMENSION power supply family. The most

outstanding features of CPS20.481-D1 are the wide DC-

input range, high efficiency, electronic inrush current

limitation, wide operational temperature range.

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 CPS20.481-D1 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.

REDUNDANCY MODULES YR40.482 – (2x 20A Inputs, 1x 40A output) The YR40.482 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 YR40.482 does not require an additional auxiliary voltage and is self-powered even in case of a short circuit across the output.

CPS20.481-D1 48V, 10A, DC/DC CONVERTER C-Series 22. APPLICATION NOTES 22.1. PEAK CURRENT CAPABILITY The DC/DC converter 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.

CPS20.481-D1 48V, 10A, DC/DC CONVERTER 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. Provided, that the negative pole is grounded. If the positive pole is grounded, an additional external fast-acting input fuse in the negative input is required (E.g.

The output voltage of all DC/DC converters 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.

CPS20.481-D1 48V, 10A, DC/DC CONVERTER C-Series 22.7. SERIES OPERATION DC/DC converters 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.

(Four 12V batteries in series) Instructions for charging batteries: a) b) Set output voltage (measured at no load and at the battery end of the cable) very precisely to the end-of-charge voltage.

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 DC/DC converter. Therefore, two different derating curves for continuous operation can be found below: Curve A1 Curve A2 Recommended output current.
