RODUCT DESCRIPTION
The Dimension CP-Series are cost optimized power
supplies without compromising quality, reliability and
performance. The CP-Series is part of the DIMENSION
power supply family. The most outstanding features
of CP20.481 are the high efficiency, electronic inrush
current limitation, active PFC, wide operational
temperature range. The small size is achieved by
a synchronous rectification, LLC technology and by
many further technological design details.
The C-Series includes all the essential basic functions.
The device has a power reserve of 20% included,
which may even be used continuously at temperatures
up to +45°C. Additionally, the CP20.481 can deliver
about 3 times the nominal output current for 12ms
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
make this unit suitable for nearly every situation.

    CP20.481 23.3. YR40.482 – REDUNDANCY MODULE The YR40.482 is a dual redundancy module, which can be used to build 1+1 or N+1 redundant systems. The device is equipped with two 20A nominal input channels, which are individually decoupled by utilizing MOSFET technology. The output can be loaded with a nominal 40A continuous current.

  • Page 26: Application Notes

    CP20.481 24. Application Notes 24.1. PEAK CURRENT CAPABILITY The device 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 27: Output Circuit Breakers

    CP20.481 24.2. OUTPUT CIRCUIT BREAKERS Standard miniature circuit breakers (MCB’s or UL 1077 circuit breakers) are commonly used for AC-supply systems and may also be used on 48V branches. MCB’s are designed to protect wires and circuits. If the ampere value and the characteristics of the MCB are adapted to the wire size that is used, the wiring is considered as thermally safe regardless of whether the MCB opens or not.

  • Page 28: Parallel Use To Increase Output Power

    CP20.481 24.3. PARALLEL USE TO INCREASE OUTPUT POWER Devices 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 29: Parallel Use For Redundancy

    CP20.481 24.4. PARALLEL USE FOR REDUNDANCY Please note that there are variants with built-in redundancy are available in the CP20 series. Check CP20.241-Rx units. 1+1 Redundancy: Devices can be paralleled for redundancy to gain higher system availability. Redundant systems require a certain amount of extra power to support the load in case one device fails.

  • Page 30: Series Operation

    CP20.481 24.5. SERIES OPERATION Devices 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.

  • Page 31: Use In A Tightly Sealed Enclosure

    CP20.481 24.8. 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. In such situations, the inside temperature defines the ambient temperature for the power supply. The power supply is placed in the middle of the box, no other heat producing items are inside the box.

  • Page 32: Mounting Orientations

    CP20.481 24.9. 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 listed lifetime and MTBF values from this datasheet apply only for the standard mounting orientation. The following curves give an indication for allowed output currents for altitudes up to 2000m (6560ft).
