ESCRIPTION
The CP20.248 is a DIN-rail mountable single-phase-input power
supply, which provides a floating, stabilized and galvanically
separated SELV/PELV output voltage.
The device has a condition display integrated which shows real-
time and recorded data informing about the condition of the
power supply and the power line.
A DC OK signal, an alarm signal and remote ON/OFF make the
unit suitable for many applications, where preventive function
monitoring and remote control can help to avoid costly
downtimes.
The device has a power reserve of 20% included, which may
even be used continuously up to +45°C. Additionally it can
deliver 3 times the nominal output current for 12ms, which
helps to trip fuses on faulty output branches.
The device is equipped with a "Single Use / Parallel Use" feature,
which enables a load sharing between power supplies when
they are connected in parallel.
The Dimension CP-Series are cost optimized power supplies
without compromising quality, reliability and performance. The
most outstanding features of this series are the high efficiency,
electronic inrush current limitation, active PFC, wide operational
temperature range and the extraordinary small size.

    CP20.248 24V, 20A, 480W, S CP-Series INGLE HASE 26.2. O UTPUT IRCUIT REAKERS Standard miniature circuit breakers (MCB’s or UL 1077 circuit breakers) are commonly used for AC-supply systems and may also be used on 24V 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.

Two 12V SLA or VRLA batteries are needed in series connection. Instructions for charging batteries: Use only matched batteries when putting 12V types in series.
  • Page 31: Parallel Use For Redundancy

    CP20.248 24V, 20A, 480W, S CP-Series INGLE HASE 26.6. P ARALLEL SE FOR EDUNDANCY 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. The simplest way is to put two devices in parallel. This is called a 1+1 redundancy. In case one device fails, the other one is automatically able to support the load current without any interruption.

Such a P ower S upply phase-to-phase connection is allowed as long as the supplying voltage is below 240V +10% Ensure that the wire, which is connected to the N-terminal, is appropriately fused.

    CP20.248 24V, 20A, 480W, S CP-Series INGLE HASE 26.9. M OUNTING RIENTATIONS Mounting orientations other than the standard mounting orientation 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).
