1. DC/DC converter
1.1. Brief description
• 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
I
out
= 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.
1.2. Application
• 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 elec-
tronic 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.
