The DCC 24 is a switched step-down converter, which converts DC voltage in the range 20 V to 60 V on the input side to 13.8 V / 2.5 A DC on the output side.
The converter has high efficiency, typically better than 80 %.
It is resistant to polarity reversal of the input voltage, undervoltage at the input, shorting at the output and connecting voltage to the output terminals. If the input voltage descents under 16.5 V (at
Iout= 2,5 A) then the converter switched off to prevent the unstable conditions.
Assembly on to DIN rail TS35.
Minimum ground plan dimension: 35 × 75 mm.
Maximum demand charge: 35 W.
The DCC24 converter is suitable for DC voltage supply to electrical devices when it is necessary to convert DC voltages in the 20 V to 60 V range to 13.8 V DC and with a maximum output current of 2.5 A.
It is typically used for supplying MORSE system devices (MR25 and MR400 radio modems) media where the backed up distribution is 24 V DC (or 48 V DC).
Due to its high efficiency and small dimensions the DCC24 converter finds use in supplying electronic equipment located in mobile devices with a 24 V DC on-board network.
The design and construction of this device allows for long-term loading and for this reason it is primarily determined for continuously running applications.
DC/DC converter is designated for Assembly on to DIN rail TS35, ground plan dimension is 35 × 75 mm.
Connections of input and output wires to terminals of the converter are shown in the following diagram:
Terminals are of ENTRELEC type and enable connection of conductors with maximum cross section of 2,5 mm2.
