PRODUCT 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 for a variety

of applications makes this unit suitable for nearly every

situation.

PRELIMINARY CP20.481 48V, 10A, SINGLE PHASE INPUT CP-Series 6. OUTPUT The output provides a SELV/PELV rated voltage, which is galvanically isolated from the input voltage. The device is designed to supply any kind of loads, including capacitive and inductive loads. If extreme large capacitors, such as EDLCs (electric double layer capacitors or “UltraCaps”) with a capacitance > 0.25F are connected to the output, the unit might charge the capacitor in an intermittent mode.

PRELIMINARY CP20.481 48V, 10A, SINGLE PHASE INPUT CP-Series 2) At heavy overloads (when output voltage falls below 13V), the power supply delivers continuous output current for 2s. After this, the output is switched off for approx. 18s before a new start attempt is automatically performed. This cycle is repeated as long as the overload exists. If the overload has been cleared, the device will operate normally. See Fig. 6-3. Fig. 6-2 Output voltage in “parallel use” mode, typ. Fig.

PRELIMINARY CP-Series CP20.481 48V, 10A, SINGLE PHASE INPUT 22.2. UF20.481 BUFFER MODULE The UF20.481 buffer module is a supplementary device for DC 48V power supplies. It delivers power to bridge typical mains failures or extends the hold-up time after the AC power is turned off. When the power supply provides a sufficient voltage, the buffer module stores energy in the integrated electrolytic capacitors. When the mains voltage is lost, the stored energy is released to the DC-bus in a regulated process.

PRELIMINARY CP20.481 48V, 10A, SINGLE PHASE INPUT CP-Series 23. APPLICATION NOTES 23.1. PEAK CURRENT CAPABILITY The unit 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.

PRELIMINARY CP20.481 48V, 10A, SINGLE PHASE INPUT CP-Series 23.2. 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.

Four 12V SLA or VRLA batteries are needed in series connection. Instructions for charging batteries: a) Use only matched batteries when putting 12V types in series. b) Ensure that the ambient temperature of the power supply stays below 40°C.

PRELIMINARY CP20.481 48V, 10A, SINGLE PHASE INPUT CP-Series Unit A 23.5. PARALLEL USE TO INCREASE OUTPUT POWER Input Devices can be paralleled to increase the output power. The output voltage of all devices shall be adjusted to the same value (±100mV) in “Single Use” mode with the same load conditions on all devices, or the devices can be left with the factory settings. After the adjustments, set the unit to “Parallel Use” mode, in order to achieve load sharing.

PRELIMINARY CP20.481 48V, 10A, SINGLE PHASE INPUT CP-Series 23.6. PARALLEL USE FOR REDUNDANCY 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 phase-to-phase connection is allowed as long as the supplying voltage is below 240V+10%. 240V +10% max.

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). Fig.
